Aquo-ethanolic extract of Lilii Bulbus attenuates dexamethasone-induced muscle loss and enhances muscle strength in experimental mice

Traditionally, Lilium lancifolium bulb is known for its ability to nourish yin, nourish the lungs, clear the heart, soothe coughs, reduce irritability, and calm the mind. In Oriental Medicine, it is categorized as a tonic remedy for alleviating symptoms of fatigue and enhancing the strength of bones and muscles.In this study, we aimed to validate the effectiveness of the aquo-ethanolic extract of Lilli Bulbus (LBE) in a dexamethasone (DEX)-induced muscle atrophy model, both in vitro and in vivo, and elucidate its mechanism of action through muscle transcriptome analysis. The effects of LBE on the viability and myotube density of C2C12 myoblasts and differentiated C2C12 myotubes with and without DEX treatment were investigated. LBE pretreatment protected C2C12 myoblast cells and increased the muscle density of C2C12 myotubes in response to DEX. LBE showed potent free radical scavenging activities in cell-free biochemical assays as well as antioxidant activity in C2C12 myoblasts. LBE also exhibited protective effects in an experimental animal model of DEX-induced muscle atrophy, showing muscular function and motor coordination recovery. Transcriptomic analysis of three different muscle tissues from mice with DEX-induced muscle atrophy showed that the regulation of the extracellular matrix was perturbed by glucocorticoid treatment, and this perturbation was reversed by LBE treatment.Collectively, LBE alleviated skeletal muscle loss and maintained muscle function from the chronic toxicity of DEX by protecting muscle cells from various stressful conditions, as well as DEX itself, inhibiting muscle protein degradation, and preserving the muscle tissue microenvironment.

Rehmannia glutinosa DC.-Lilium lancifolium Thunb. in the treatment of depression: a comprehensive review and perspectives

BackgroundIn recent years, the incidence of depression, recognized as a serious psychological disorder, has escalated rapidly. Rehmannia glutinosa DC. (Scrophulariaceae; Rehmanniae Radix, Crude drug) and Lilium lancifolium Thunb. (Liliaceae; Lilii bulbus, Crude drug) constitute a classic anti-depressant combination, exhibiting pharmacological effects that include anti-depressive, anti-anxiety, and anti-inflammatory properties. Current clinical studies have demonstrated that Baihe Dihuang Decoction, a traditional Chinese herbal compound, is effective in treating depression. However, the majority of scholars have predominantly examined Rehmannia glutinosa and Lilium in isolation, and a comprehensive elucidation of their principal active metabolites and pharmacological mechanisms remains lacking.MethodsA comprehensive literature search was conducted as of 29 September 2024, utilizing databases such as PubMed, CNKI, Wanfang Data, Baidu Scholar, and Google Scholar. Additionally, classical texts on Chinese herbal medicine, the Chinese Pharmacopoeia, as well as doctoral and master’s theses, were included in the collected materials. The search employed specific terms including “R. glutinosa,” “Lilium,” “Baihe Dihuang decoction,” “application of Baihe Dihuang decoction,” “pathogenesis of depression,” and “pharmacological action and mechanism of depression.ResultsThis paper reviewed the traditional applications and dosages of the R. glutinosa-Lilium as documented in Chinese medical classics, thereby establishing a foundation for the contemporary development and clinical application of the classical formula Baihe Dihuang Decoction. Additionally, recent years have seen a comprehensive review of the pharmacological effects and mechanisms of R. glutinosa-Lilium and its principal metabolites in the context of depression.ConclusionThis paper has reviewed the active metabolites of R. glutinosa-Lilium and demonstrated its efficacy in the treatment of depression, as well as its role in modulating the underlying mechanisms of the disorder. The findings aim to serve as a reference for further research into the mechanisms of depression, its clinical applications, and the development of novel therapeutic agents.

A novel combination against skin aging via promoting the synthesis of biological collagen

Supplementing collagen is considered to contribute to delaying skin aging. In this work, we developed a novel combination for improving skin aging by stimulating the biosynthesis of collagen. By screening a library of Chinese herbal medicines (CHM), we found that Angelicae Dahuricae Radix (Baizhi), Lilii bulbus (Baihe), Glycyrrhizae radix et rhizoma (Gancao), and Jujubae fructus (Dazao) substantially increased the mRNA expression levels of type I collagen, suggesting their potential anti-skin-aging activity. To keep the structural integrity of collagen, prolyl 4-hydroxylase (P4H), a key enzyme in collagen synthesis, was recombinantly expressed in Escherichia coli. In addition, the transfersome with added P-4H was prepared to improve the transdermal absorption of combination. Vitamin C (VC), the substrate required for the activity of P4H, was also incorporated into the combination. Eventually, an optimal combination, consisting of Baizhi, Baihe, Gancao, P4H transfersome and VC, was obtained by a series of combination experiments. Based on traditional CHM and modern biological agents, we developed a novel combination against skin aging by promoting the synthesis of collagen. Collectively, the combination show the high potential of application to delay skin aging

Antiseizure effects of Lilii Bulbus on pentylenetetrazol kindling-induced seizures in mice: Involvement of Reelin, Netrin-1, and semaphorin

Lilii Bulbus (Lilium lancifolium Thunberg) has a proneurogenic effect on the hippocampus. However, its effects on epilepsy and associated pathological features remain unknown. In this study, we investigated the antiseizure effects of a water extract of Lilii Bulbus (WELB) in mouse model of pentylenetetrazol (PTZ)-induced seizure. Mice were injected with PTZ once every 48 h until full kindling was achieved. WELB (100 and 500 mg/kg) was orally administered once daily before PTZ administration and during the kindling process. We found that WELB treatment protected against PTZ-induced low seizure thresholds and high seizure severity. Further, WELB-treated mice showed attenuated PTZ kindling-induced anxiety and memory impairment. Immunostaining and immunoblots showed that hyperactivation and ectopic migration of dentate granule cells (DGCs) were significantly reduced by WELB treatment in PTZ kindling-induced seizure mice. Staining for mossy fiber sprouting (MFS) using Timm staining and ZnT3 showed that WELB treatment significantly decreased PTZ kindling-induced MFS. Furthermore, the increased or decreased expression of proteins related to ectopic DGCs (Reelin and Dab-1), MFS (Netrin-1, Sema3A, and Sema3F), and their downstream effectors (ERK, AKT, and CREB) in the hippocampus of PTZ kindling mice was significantly restored by WELB treatment. Overall, our findings suggest that WELB is a potential antiseizure drug that acts by reducing ectopic DGCs and MFS and modulating epileptogenesis-related signaling in the hippocampus.

Integrative analysis of metabolome and transcriptome provides new insights into functional components of Lilii Bulbus

ObjectiveLilium brownii var. viridulum (LB) and L. lancifolium (LL) are the main sources of medicinal lily (Lilii Bulbus, Baihe in Chinese) in China. However, the functional components of these two species responsible for the treatment efficacy are yet not clear. In order to explore the therapeutic material basis of Lilii Bulbus, we selected L. davidii var. willmottiae (LD) only used for food as the control group to analyze the differences between LD and the other two (LB and LL). MethodsMetabolome and transcriptome were carried out to investigate the differences of active components in LD vs LB and LD vs LL. Data of metabolome and transcriptome was analysed using various analysis methods, such as principal component analysis (PCA), hierarchical cluster analysis (HCA), and so on. Differentially expressed genes (DEGs) were enriched through KEGG and GO enrichment analysis. ResultsThe PCA and HCA of the metabolome indicated the metabolites were clearly separated and varied greatly in LL and LB contrasted with LD. There were 318 significantly differential metabolites (SDMs) in LD vs LB group and 298 SDMs in LD vs LL group. Compared with LD group, the significant up-regulation of steroidal saponins and steroidal alkaloids were detected both in LB and LL groups, especially in LB group. The HCA of transcriptome indicated that there was significant difference in LB vs LD group, while the difference between LL and LD varied slightly. Additionally, 47 540 DEGs in LD vs LB group and 18 958 DEGs in LD vs LL group were identified. Notably, CYP450s involving in the biosynthesis of steroidal saponins and steroidal alkaloids were detected, and comparing with LD, CYP724, CYP710A, and CYP734A1 in LB and CYP90B in LL were all up-regulated. ConclusionThis study suggested that steroidal saponins and steroidal alkaloids maybe the representative functional components of Lilii Bulbus, which can provide new insights for Lilii Bulbus used in the research and development of classic famous formula.

Structural elucidation of a non-starch polysaccharides from Lilii Bulbus and its protective effects against corticosterone-induced neurotoxicity in PC12 cells.

Lilii Bulbus is a folk medicine for both culinary and medicinal purpose. In traditional medicine theory, Lilii Bulbus is usually used as an complementary therapy for nourishing the heart and lung, clearing heat in the treatment of mental instability and depression. In this study, NLPS-1a (Mw = 2610 Da, DP = 16), a water-soluble non-starch Lilii Bulbus polysaccharides, was isolated and purified. Structural analysis showed that NLPS-1a mainly contained Man and Glc with a molar ratio of 11.137 and 9.427. The glycosidic linkages of NLPS-1a were 1,3-Manp (59.93%), 1,2-Glcp (37.93%), T-Glcp (1.21%) and T-Manp (0.93%), indicating the highly-linear structures. In addition, NLPS-1a could significantly repair the injury of PC12 cells induced by corticosterone (CORT), reduce Lactate dehydrogenase (LDH) leakage and decrease the cell apoptosis in a dose-dependent manner. Above all, the results indicated that NLPS-1a had protective effects against CORT-induced neurotoxicity in PC12 cells, and might be a natural antidepressant, which enriched the study of the metabolic mechanism between herbal polysaccharides and antidepressant.

Identification and discrimination of lilii bulbus origins based on lipidomics using UHPLC–QE-Orbitrap/MS/MS combined with chemometrics analysis

Lilium brownii var. viridulum Baker is an economically important plant, and its bulbs are popular among consumers for their high nutritional value. Due to the influence of environment, the chemical composition of lily from different origin is different, which leads to the different medicinal and nutritional values. Thus, it is very significant and necessary to discriminate the origins of lily. In this study, lipid classes and molecular species of lily samples from eight origins were identified and quantified by UHPLC-QE-Orbitrap/MS/MS and combined with chemometrics for modeling and analysis. The results showed that a total of 16 lipid classes and 88 lipid molecules were identified and quantified. The partial least squares discriminant analysis (PLS-DA) showed that there were significant differences in lipid metabolites between LH (Daodi) and other origins. And 39 characteristic compounds such as TAG 16:0/18:0/18:2, TAG 18:0/18:1/18:2, and LDGCC 15:2 could be used as the markers to identify the geographical origin of lily. This study established a new method to identify the origin traceability of lily in different production areas, and provided a theoretical basis to evaluate the nutritional value of lilies from different origins.

Pro-neurogenic effects of Lilii Bulbus on hippocampal neurogenesis and memory

Lilii Bulbus, the bulb of tiger lily, has anti-oxidant and anti-tumorigenic properties. However, the effects of Lilii Bulbus on learning, memory, and hippocampal neurogenesis remain unknown. This study investigated whether water extract of Lilii Bulbus (WELB) affects memory ability and hippocampal neurogenesis. Behavioral analyses (Morris water maze and passive avoidance test), immunohistochemistry, cell proliferation assay, and immunoblot analysis were performed. WELB (50 and 100 mg/kg; for 14 days) enhanced memory retention and spatial memory in normal mice as well as in scopolamine-treated mice with memory deficits. Furthermore, the administration of WELB significantly increased the number of proliferating cells and surviving newborn cells in the dentate gyrus of the hippocampus in normal mice. We found that WELB has a pro-neurogenic effect by increasing the activation of brain-derived neurotrophic factor (BDNF)/cAMP response element-binding protein (CREB) and mitogen-activated protein kinase kinase/extracellular signal-regulated kinase (MEK/ERK) in the hippocampus. Moreover, we confirmed that WELB (100 and 200 μg/ml) significantly increased NE-4 C and primary embryonic NSCs proliferation. Inhibition/knockdown of MEK/ERK blocked WELB-induced MEK/ERK phosphorylation and NSCs proliferation. Hence, MEK/ERK activation was required in WELB-induced NSCs proliferation. Our study demonstrates the first evidence for WELB promoting hippocampal neurogenesis and memory; pro-neurogenic activity may enhance brain plasticity, with implications for treating neurodegenerative diseases.

Effect of sulfur fumigation on quality and safety of Lilii Bulbus

Lilii Bulbus is a commonly used Chinese herbal medicine with both medicinal and edible values, while the market products usually has the problem of sulfur fumigation. Therefore, the quality and safety of Lilii Bulbus products deserve attention. In this study, ultra-high performance liquid chromatography-time of flight-tandem mass spectrometry(UPLC-Q-TOF-MS/MS) was combined with principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) to analyze the differential components of Lilii Bulbus before and after sulfur fumigation. We identified ten markers generated after sulfur fumigation, summarized their mass fragmentation and transformation patterns, and verified the structures of phenylacrylic acid markers of sulfur fumigation. At the same time, the cytotoxicity of the aqueous extracts of Lilii Bulbus before and after sulfur fumigation was evaluated. The results showed that in the concentration range of 0-800 mg·L~(-1), the aqueous extract of Lilii Bulbus after sulfur fumigation had no significant effect on the viability of human liver LO2 cells, human renal proximal tubular HK-2 cells, and rat adrenal pheochromocytoma PC-12 cells. Moreover, the viability of the cells exposed to the aqueous extract of Lilii Bulbus before and after sulfur fumigation showed no significant difference. This study identified phenylacrylic acid and furostanol saponins as markers of sulfur-fumigated Lilii Bulbus for the first time, and made clear that proper sulfur fumigation of Lilii Bulbus would not produce cytotoxicity, providing a theoretical basis for the rapid identification and quality and safety control of sulfur-fumigated Lilii Bulbus.

High-throughput screening and quantification of pesticides in Lilii Bulbus using ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry.

Lilii Bulbus is a notable flower in Chinese cuisine, and has also been used as a Chinese herbal medicine for over 2000 years. This work presents an analytical method for rapidly screening multiple pesticide residues in Lilii Bulbus using ultra-high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS). For sample pre-treatment, the QuEChERS method is employed, and targeted MS/MS is adopted for data acquisition. Moreover, a database containing 515 pesticides with accurate mass database and a high-resolution fragment ion spectrum library is established in this work. In addition, the qualitative and quantitative results of the screening method are validated. The results show that within the linear concentration range of 2 to 200 μg L-1, for each pesticide, 89.3% of the pesticides exhibit linear correlation coefficients R2 equal to or exceeding 0.990. The limit of quantification for all pesticides is below 50 μg kg-1. With a recovery of 70% to 120% and RSD ≤ 20% as the satisfactory standards, 387 (75.0%), 411 (79.7%) and 420 (81.4%) pesticides meet the standards at the three addition levels of 10 μg kg-1, 20 μg kg-1, and 100 μg kg-1, respectively. By utilizing the proposed method, pesticide residues in 100 samples are investigated, providing scientific data to ensure the safety of pesticide residues and demonstrating the general applicability of the method for routine monitoring of pesticide residues in Lilii Bulbus.

Moisture content measurement model of whole package of Chinese medicinal materials based on microwave transmission technology

In view of the relatively low representativeness of manual sampling inspection, and long time-consuming in oven detection of moisture content, which delayed the subsequent production period, this paper proposed a scheme for rapid moisture quantitative detection for Chinese medicinal materials by microwave transmission technology, and took 8 different types of Chinese medicinal mate-rials as examples to analyze the feasibility and reliability of the scheme for the detection results of moisture content of the whole package of Chinese medicine. In the experiment, the least square method was used to establish the measurement model of microwave absorption rate-moisture content for each kind of medicinal material. The results showed that the microwave transmission measurement of moisture content achieved high-precision measurement of the moisture content of Schisandrae Chinensis Fructus, Ziziphi Spinosae Semen, Poria, Pheretima, Lilii Bulbus, Scutellariae Radix, and Galli Gigerii Endothelium Corneum. The measurement model of Ziziphi Spinosae Semen had the highest accuracy, and the R~2 and root mean square error of the validation set were 0.951 5 and 0.15%, respectively. At the same time, this study found that the microwave absorption intensity of animal medicines including Pheretima and Galli Gigerii Endothelium Corneum was much weaker than that of plant medicines such as Schisandrae Chinensis Fructus, but there was also a good linear relationship between microwave absorption and moisture content, which proved the universality of this method. However, this method was not suitable for Phellodendri Chinensis Cortex because its package contained iron wire. For the whole package of medicinal materials with uniform density and no metal inside, the microwave transmission technology for moisture content measurement can be used to detect the moisture content, which is an effective alternative method to detect the moisture content of medicinal materials.

Geographical origin and species identification of lilii bulbus using C/N/H/O stable isotopes and multi-elemental combined chemometrics

Lilii bulbus is an important food in China with medicinal and edible functions, and its quality and price are closely related to its geographical origin. In this work, 4 stable isotopes (δ13C, δ15N, δ2H and δ18O) and 41 mineral elements of lilii bulbus samples from 11 origins and 4 species were collected and combined with chemometrics to identify origins and species. ANOVA and principal component analysis (PCA) showed significant differences (P < 0.05) in stable isotopes and multiple elements in lilii bulbus samples from different origins, and Cu, Zn, K, δ18O, Sr and Li are important contributors to the classification. Partial least squares discriminant analysis (PLS-DA) and orthogonal partial least squares discriminant analysis (OPLS-DA) were used to classify different species of lilii bulbus with good classification performance, while indicating that K, Ca, Na and Mg elements could be used as effective elements for species classification. The external validation model of OPLS-DA showed high accuracy (>89%) for lilii bulbus species classification. This study shows that stable isotopes and multi-elemental combined chemometrics provide an effective method for lilii bulbus origin and species identification.

Effects of different boiling processes on chemical compositions of Lilii Bulbus soup.

Lilii Bulbus, an edible Chinese herbal medicine, has a long history in medicine. However, research on effectively boiling Lilii Bulbus is rare. To make the more nutritious Lilii Bulbus soup, the optimized boiling process, using an alternate heating mode by decoction pot carrying a mixture of water and Chinese liquor at the ration of 9:1, was established in this study. Compared to the soup prepared by the daily process, the polysaccharide amount improved by 54%, and the total heavy metals decreased by 33.5% using the optimized boiling process. In addition, the total saponins at 34.3 μg/g were determined in the soup prepared by the optimized process. Meanwhile, the colchicine content in the boiled Lilii Bulbus soup was undetectable using the optimized process. This research performs an optimized boiling process for making Lilii Bulbus soup, and provides a reference for generating high commercial value from Lilii Bulbus soup in the future.

Geographical origin traceability of medicine food homology species based on an extract-and-shoot inductively coupled plasma mass spectrometry method and chemometrics

In this work, an extract-and-shoot sample preparation method based on inductively coupled plasma mass spectrometry (ICP-MS) was proposed for fast and efficient geographical origin traceability of medicine food homology species (MFHs). It was not essential to know the absolute contents of mineral elements in MFHs. Exploratory analysis of the MFHs samples was executed by the principal component analysis (PCA) and hierarchical cluster analysis (HCA). The mass spectrometry relative intensities of 46 mineral elements in combination with partial least squares discriminant analysis (PLS-DA) to classify-three MFHs, which were Atractylodis macrocephalae Rhizoma (AMR), Lilii Bulbus (LB), and adlay (AD). Overall, the supervised PLS-DA achieved satisfactory classification results. In addition, variable importance in projection (VIP) was employed to select the main classification indicators. In brief, the proposed method was simple, rapid, environmental, and reliable because it does not require standard solutions of mineral elements and complicated pretreatment, is less time-consuming, and acquires satisfactory results.

Integrative analysis of metabolome and transcriptome provide new insights into the bitter components of Lilium lancifolium and Lilium brownii

Lilium, a perennial crop with great ornamental, medicinal and edible value, has been frequently used as functional food and medicine. Lilium lancifolium Thunb. (L. lancifolium) and Lilium brownii F.E.Brown var.viridulum Baker (L. brownii) are the most used medicinal species in China. However, the flavor compounds of these two species have not yet been clear. Here, metabolomics and transcriptome analysis were used to reveal the difference of the bitter substances of L. lancifolium and L. brownii. Qualitative results indicated that nine compounds are commonly existed in L. lancifolium and L. brownii, while nine compounds are unique in L. lancifolium and eight compounds are unique in L. brownii. Furthermore, quantitative results revealed that the content of regaloside A in L. lancifolium was nearly 2–7 folds higher than that of L. brownii, and the content of regaloside B in L. lancifolium was about 4–16 folds higher than that of L. brownii. Regaloside C and E were not detected in L. brownii. Transcriptome analysis showed that there were 90 unique genes up-regulated in L. lancifolium samples in the pathway of phenylpropanoid biosynthesis and 75 unique genes up-regulated in L. brownii samples, which could be related to the different content and chemical structure specificity of phenylpropanoid glycerol glucosides in L. lancifolium and L. brownii. The results of our in-deep research provide new insights into the bitter substances of L. lancifolium and L. brownii, and a further consideration for the chemical consistency and quality evaluation for Lilii bulbus.

Ziyin Huatan Recipe, a Chinese herbal compound, inhibits migration and invasion of gastric cancer by upregulating RUNX3 expression

ObjectivesZiyin Huatan Recipe (ZYHT), a traditional Chinese medicine comprised of Lilii Bulbus, Pinelliae Rhizoma, and Hedyotis Diffusa, has shown promise in treating gastric cancer (GC). However, its potential mechanism has not yet been clearly addressed. This study aimed to predict targets and molecular mechanisms of ZYHT in treating GC by network pharmacology analysis and to explore the role of ZYHT in GC both in vitro and in vivo. MethodsTargets and molecular mechanisms of ZYHT were predicted via network pharmacology analysis. The effects of ZYHT on the expression of metastasis-associated targets were further validated by Western blot and quantitative real-time polymerase chain reaction. To explore the specific molecular mechanisms of the effects of ZYHT on migration and invasion, the runt-related transcription factor 3 (RUNX3) gene was knocked out by clustered regularly interspaced short palindromic repeats/Cas9, and lentiviral vectors were transfected into SGC-7901 cells. Then lung metastasis model of GC in nude mice was established to explore the anti-metastasis effect of ZYHT. Western blot and immunohistochemistry were used to explore the impact of ZYHT on the expression of metastasis-related proteins with or without RUNX3 gene. ResultsThe network pharmacology analysis showed that ZYHT might inhibit focal adhesion, migration, invasion and metastasis of GC. ZYHT inhibited the proliferation, migration and invasion of GC cells in vitro via regulating the expression of metastasis-associated targets. Knocking out RUNX3 almost completely reversed the cell phenotypes (migration and invasion) and protein expression levels elicited by ZYHT. In vivo studies showed that ZYHT inhibited the metastasis of GC cells to the lung and prolonged the survival time of the nude mice. Knocking out RUNX3 partly reversed the metastasis of GC cells to the lung and the protein expression levels elicited by ZYHT. ConclusionZYHT can effectively inhibit the invasion and migration of GC in vitro and in vivo, and its molecular mechanism may relate to the upregulation of RUNX3 expression.

Supplementation with Ginseng, Lilii Bulbus, and Poria induces alterations in the serum metabolic profile of healthy adults

The preventive and therapeutic effects of herbal supplementation containing Ginseng, Lilii Bulbus, and Poria (GLP) on inflammation and oxidative stress in healthy adults have been demonstrated in our previous studies. However, the underlying mechanisms of organism protection by GLP remain unclarified, and few studies have used metabolomics to investigate comprehensive changes before and after GLP supplementation. Based on previous research, we conducted a placebo-controlled trial among 82 healthy adults in Wuhan, China, using a metabolomics approach with ultra-performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS/MS) and multivariate statistical methods to analyze serum metabolite alterations in participants before and after GLP supplementation. Furthermore, 14 discriminant metabolites related to lipid metabolism, inflammation and oxidative stress, energy metabolism, and coenzyme A metabolism were significantly different between the before- and after-GLP groups (P < 0.0001). Nine metabolites were significantly decreased in the serum samples from the after-GLP group compared with the before-GLP group, while five metabolites were significantly increased. These metabolites could be critical components associated with the anti-inflammatory, antioxidant, and hypolipidemic activities of GLP, indicating the potential complementary role of GLP supplements in the primary prevention of dysfunctional metabolism caused by potential diseases such as cardiovascular disease. This study provides a valuable reference for cardiovascular health protection and disease prevention.

To investigate the potential molecular mechanism of the combination of Platycodonis Radix and Lilii Bulbus with the homology of medicine and food in the treatment of pneumonia by means of network pharmacology and in vitro verification experiment. Under the condition of bioavailability(OB)≥30% and drug-like(DL)≥0.18, the active components of Platycodonis Radix and Lilii Bulbus were screened in TCMSP database; the prediction targets of active components were searched from TCMSP, DrugBank and other databases, and the potential targets of pneumonia were obtained through GeneCards and OMIM database. The common targets were obtained by the intersection of drug and disease targets. The PPI network of common targets was constructed by STRING 11.0, and the core targets were obtained by topological analysis. Then the core targets received GO and KEGG analysis with use of WebGestalt and Metascape. The &quot;component-target-pathway&quot; network was constructed with the help of Cytoscape 3.7.1 software, and the component-target molecular docking verification was carried out with Discovery Studio 2016 software. Finally, the core targets and pathways were preliminarily verified in vitro. In this study, 12 active components were screened, 225 drug prediction targets and 420 potential diseases targets were obtained based on data mining method, and 14 core targets were obtained by topological analysis, including TNF, MMP9, AKT1, IL4 and IL2. The enrichment results of GO and KEGG showed that &quot;Platycodonis Radix and Lilii Bulbus&quot; drug pair may regulate inflammation, cell growth and metabolism by acting on 20 key signaling pathways such as TNF and IL-17, thereby exerting anti-pneumonia effects. The results of molecular docking showed that 12 active components had good binding ability with 14 core targets. In vitro experiment results showed that the core components of &quot;Platycodonis Radix and Lilii Bulbus&quot; drug pair could inhibit the expression of MMP9 and TNF-α by regulating TNF signal pathway. This study confirmed the scientificity and reliability of the prediction results of network pharmacology, and preliminarily revealed the potential molecular mechanism of the compatibility of Platycodonis Radix and Lilii Bulbus in the treatment of pneumonia. It provides a novel insight on systematically exploring the mechanism of the compatible use of Platycodonis Radix and Lilii Bulbus, and has a certain reference value for the research, development and application of new drugs.
