This work used experimental methods to evaluate the chemical composition of GC-MS, HPTLC-based bioautographaphy, antioxidant, anti-diabetic, and protein denaturation properties of the Neptunia prostrata Linn (family: Mimosaceae) whole plant and leaves. Three methods, namely DPPH, metal chelating, and reducing power assays, were used to estimate the antioxidant effects. In addition, α-amylase, a carbohydrate-hydrolyzing enzyme, was targeted to test the anti-diabetic activity. The protein denaturation assay was used to evaluate the anti-inflammatory activity of the plant. GC-MS, an important analytical tool, was performed to identify bioactive compounds of medicinal plants used in pharmaceutical industries. Biochemical derivatization HPTLC-based bioautography with DPPH was executed to identify antioxidant agents from N. prostrata. The validated HPTLC method was used to quantify identified antioxidant agents. The stability of compounds, preparation of calibration curves, linearity, range, precision, limit of detection, limit of quantification, robustness, and accuracy are examined to develop a robust method. Higher total phenolic content (TPC) content was observed in N. prostrata hydroalcoholic extract of the whole plant (81.12 ± 4.19 mg GAE/g) and methanolic extract of leaves (105.16 ± 3.11 mg GAE/g). Methanolic extract of N. prostrata leaves showed significantly high antioxidant potential for all DPPH (IC50:28.05 ± 1.78 µg/mL), metal chelating (IC50:1598 ± 23.51 µg/mL), and reducing power assay compared to standard ascorbic acid (DPPH assay: IC50:24.14 ± 2.34 µg/mL and metal chelating: IC50:1301.16 ± 6.14 µg/mL). N. prostrata aqueous extract of the whole plant (IC50:179.47 ± 10.59 µg/mL) and leaves (IC50:130.86 ± 3.58 µg/mL) showed significantly high α-amylase inhibitory activity as compared to standard acarbose (IC50:148.62 ± 7.84 µg/mL). Methanolic extract of whole plants (IC50:131.46 ± 11.81 µg/mL) and chloroform extract of leaves (IC50:122.61 ± 8.19 µg/mL) exhibited strong anti-inflammatory activity as compared to standard acetylsalicylic acid (IC50:117.77 ± 4.95 µg/mL). GC-MS analysis revealed the presence of several bioactive compounds, where 2-cyclopenten-1-one, 2-hydroxy showed the most abundant bioactive compounds in the plant with 17.01%. HPTLC-bioautography identified three phenolic acids (chlorogenic acid, gallic acid, and 4-hydroxybenzoic acid) and one flavonoid (naringenin), further quantified with the validated HPTLC method. These findings propose that N. prostrata has therapeutic potential for treating diseases related to oxidative damage, diabetes, and inflammation, which may be due to the presence of bioactive compounds.

Bangladesh is abundant in medicinal plants. The bioactive compounds in medicinal plants provide novel therapeutic opportunity of improving human health. But, the benefit-risk balance is usually less considered during formulation of traditional medicine. However, the plants that we included in this study are not studied regarding their hemolytic and anti-venom properties. Thus, we aimed to evaluate and compare the hemolytic activity, antioxidant activity, and phospholipase A2 (PLA2) enzyme neutralization efficacy of aqueous and methanolic extracts of eight known medicinal plants including Asparagus racemosus (root), Withania somnifera (root), Syzygium cumini (leaf), Psidium guajava (leaf), Basella alba (leaf and seed), Morus indica (leaf), M. laevigata (leaf), and M. latifolia (leaf). The results of the hemolytic activity test suggested that the methanolic extracts of S. cumini, P. guajava, B. alba (leaf and seed), M. indica, M. laevigata, and M. latifolia showed significantly higher hemolytic activity compared to their aqueous extracts. The methanolic extracts of A. racemosus, W. somnifera, P. guajava, M. laevigata, and M. latifolia showed remarkable antioxidant activity. Moreover, the results of the PLA2 enzyme neutralization activity test revealed that both aqueous and methanolic extracts of P. guajava, S. cumini, and B. alba (leaf) have significant PLA2 neutralization capacity. Altogether, the aqueous extracts of all plants, except A. racemosus root, have ignorable hemolytic effect. Additionally, P. guajava and S. cumini leaf aqueous extracts have promising PLA2 inhibitory effect and may become the potential source of bioactive compounds for anti-venom drug development.

Enhancing the quality attributes of mint medicinal plant (Mentha spicata L.) through simultaneous combined ozone and infrared drying

AbstractMedicinal plants are widely used in various traditional and modern medical methods due to their therapeutic properties. Drying is a common method used to preserve the biochemical compounds of medicinal plants. Still, conventional drying methods can lead to the loss of active compounds due to exposure to high temperatures. This research aimed to design and construct an ozone generator for use in a combined dryer and evaluate the ozone, temperature, and hot air flow rate on the quality properties of mint (Mentha spicata L.). Drying experiments were conducted at varying temperatures, air flow speeds, and ozone levels. Results indicated that increasing temperature reduced total phenol and flavonoid content while increasing antioxidant capacity. Higher airflow speed positively influenced total phenol, total flavonoid content and antioxidant potency but reduced drying time. Ozone exposure increased total phenol, flavonoid content, antioxidant activity, and had minimal effect on drying time. Optimization revealed that a temperature of 52.47°C, air flow rate of 1.5 m/s, and 90.37% ozone concentration yielded favorable outcomes, including enhanced phenolic and flavonoid content, antioxidant power, and decreased energy consumption. Compared to other drying methods, the proposed ozone‐enhanced method proved superior in preserving bioactive compounds and maintaining a reasonable drying time. Overall, the research highlights the potential of ozone‐assisted drying for optimizing the quality of medicinal plants during preservation.Practical ApplicationThe paper introduces a novel and efficient method for preserving the quality of medicinal mint. By concurrently applying ozone and infrared drying techniques, this approach aims to capitalize on their synergistic effects in maintaining the plant's beneficial compounds. Ozone acts as a natural antimicrobial agent, preserving the plant's integrity, while infrared drying expedites the process without compromising the phytochemical profile. This innovative method not only ensures microbial safety and extended shelf life but also enhances the mint's aroma, flavor, and nutrient retention. The practical application of this combined technique holds promise for pharmaceutical and herbal industries, providing a valuable approach for optimizing the drying process and preserving the medicinal attributes of Mentha spicata L.

Bioactive Compounds of Endemic Medicinal Plants (Cuphea spp.) Cultured in Aquaponic Systems: A Short Study

Aquaculture waters can be associated with the modification of the phytochemical profile in plants when they are used for irrigation; thus, Integrated Agri-Aquaculture Systems such as aquaponics represent a strategy to improve the bioactive content of medicinal plants. This study aimed to analyze the effect caused by cultivation using aquaponics on the modification of the content of bioactive compounds such as phenols, flavonoids, and apigenin in Cuphea hyssopifolia and Cuphea cyanea irrigated with Cyprinus carpio waters. The results of each culture method showed unique differences (p ≤ 0.05) in the concentrations of bioactive compounds and antioxidant activity in Cuphea spp. For C. hyssopifolia in aquaponics, 76% (61.08 ± 7.2 mg g−1 GAEq) of phenols and 50% (5.62 ± 0.5 mg g−1 CAEq) of flavonoids were maintained compared to 20% (16.99 ± 0.4 mg g−1 GAEq) of phenols and 76.5% (8.19 ± 1.6 mg g−1 CAEq) of flavonoids in conventional culture. For C. cyanea in aquaponics, 91% (15.36 ± 0.8 mg g−1 GAEq) of phenols and 47% (3.52 ± 0.6 mg g−1 CAEq) of flavonoids were maintained compared to 24% (14.11 ± 1.3 mg g−1 GAEq) of phenols and 82% (1.79 ± 0.1 mg g−1 CAEq) of flavonoids in conventional culture. An increase of more than 60% in the apigenin content of C. hyssopifolia in aquaponics confirms a eustress effect related to the use of organically enriched waters. The results indicate that aquaponics can promote the biostimulation/elicitation of medicinal plants and increase their bioactive compounds, but this effect does not occur in the same way between species.

Chlorogenic acid induces apoptosis and cell-cycle arrest in colorectal cancer cells.

Apoptotic agents from natural products like phenolic compounds can be used effectively in the treatment of cancer. Chlorogenic acid (CGA) is one of the phenolic compounds in medicinal plants with anti-cancer properties. In this research, we aimed to explore the anti-cancer mode of action of CGA on colorectal cancer (CRC) cells in vitro conditions. HT-29 and HEK-293 cells were cultured after MTT assay for 24h with CGA 100µM, and without CGA. Then, flow cytometry assays and the expression of apoptosis-related genes including caspase 3 and 9, Bcl-2 and Bax, and cell cycle-related genes including P21, P53 and NF-κB at mRNA and protein levels were examined. Finally, we measured the amount of intracellular reactive oxygen species (ROS). The cell viability of all two-cell lines decreased in a dose-dependent manner. Moreover, CGA induces cell cycle arrest in HT-29 cells by increasing the expression of P21 and P53. It also induces apoptosis in HT-29 cells by mitigating Bcl-2 and NF-κB expression and elevating caspase 3 and 9 expression and ROS levels. Considering the cytotoxicity and cell cycle arrest and induction of apoptosis in the colon cancer cell line by CGA, it can be concluded that CGA is a suitable option for the treatment of colon cancer.

Abstract. Muflikhati Z, Sianipar NF, Syamsunarno MRAA, Anas. 2023. Understanding of genes encoding bioactive compounds from potential medicinal plants in indonesia as cancer cell inhibitors. Biodiversitas 24: 4645-4660. Indonesia has abundant plant diversity and enormous potential to be developed as a source of medicinal plants due to the content of bioactive chemicals in them. Potential medicinal plants from Indonesia, such as Andrographis paniculata (Sambiloto), Curcuma longa (Kunyit), Moringa oleifera (Moringa), Phyllanthus niruri (Meniran), Orthosiphon stamineus (Kumis kucing), Typhonium flagelliforme (Keladi tikus), and Zingiber officinale (Jahe), contain bioactive compounds with mechanisms that act as anticancer. Bioactive compounds with anticancer mechanisms in plants can be controlled by specific genes. Therefore, it is important to elaborate on bioactive compounds and the genes involved. This article aims to discuss the genes encoding bioactive compounds in Indonesian medicinal plants and the mechanisms that can inhibit cancer cell growth. Several genes encode anticancer compounds, such as lectin-coding genes, the stigmasterol-coding CYP710A gene, the tocopherol-coding ?-TMT gene, the fatty acid-coding FAD gene, the doxorubicin-coding DXR gene, and the chalcone synthase-coding CHS gene. These genes have mechanisms to increase the expression of several apoptosis-promoting proteins, including BCL-2 family members, in several cancer cell models. This article also describes the potential utilization and creation of molecular markers linked to genes encoding anticancer chemicals and can be used as a reference for research on medicinal plants that is still limited. Knowledge of genes encoding anticancer compounds in plants can support future research in the development of cancer drugs.

Estimating the production of withaferin A and withanolide A in Withania somnifera (L.) dunal using aquaponics for sustainable development in hill agriculture.

Humanity is suffering from huge and severe difficulties, including changes in climate, soil degradation, scarcity of water and the security of food and medicines, among others. The aquaponics system acts as a closed loop consisting of aquaculture elements and hydroponics, which may contribute to addressing these problems. The aquaponics method is quickly expanding as the requirement to increase the production of sustainable herbal products, including medicinal compounds and foods, in freshwater systems and replenish phosphorous reserves shrinks. The current work is designed to increase the production of the antioxidants withaferin A and withanolide A in two varieties (Jawahar-20 and Poshita) of W. somnifera using the aquaponics technique. Total 100 seedlings (one month old) grown in soil initially were taken to be grown in aquaponics for a time period of 6 months.And 100 seedlings were placed in pots containing soil as control for study after six months. It was observed that the higher content of withaferin A was analyzed in the root and stem samples of Jawahar-20 and Poshita from the six-month-old plant of W. somnifera. The maximum content of withanolide A was examined in the root samples of the six month-old plants of Poshita (1.879 mg/g) and Jawahar-20 (1.221 mg/g). While the 6 month old Poshita seedling grown in soil recorded less withaferin A (0.115 ± 0.009b) and withanolide A (0.138 ± 0.008d). It is concluded that Poshita was found to be more promising for the enhanced production of withaferin A and withanolide A in the aquaponics system. Moreover, the root was observed as the best source for the production of withaferin A and withanolide A and the best age of the plant is 2 years for the production compounds in medicinal plants with futuristic perspective to hill agriculture integrated farming. compounds. Thus aquaponics can be an effective approach with enhanced yield of bioactive compounds in medicinal plants with futuristic perspective to hill agriculture and integrated farming.

Phenolic Compounds of the Medicinal Plants in an Anthropogenically Transformed Environment.

In this article, the impact of an anthropogenically transformed environment on the content of pharmaceutically valuable biologically active compounds in medicinal plants is analyzed. The studied biologically active substances included phenolic compounds (flavonoids, anthocyanins, tannins, and phenolic acids). The number of transmissible forms of heavy metals (HMs), including cadmium, lead, and mercury, were discharged from factories that are present in the soil. Plants uptake these toxic metals from the soil. HM causes changes in the activity of the several enzymes such as phenylalanine ammonia lyase (PAL), chalcone synthase (CHS), chalcone isomerase (CHI) and other enzymes. These enzymes play an important role in biosynthesis of phenolic compounds in medicinal plants. It has been demonstrated that plant materials possess high antioxidant potential due to their high phenolic content. As a result, the present review discusses a thorough investigation of anthropogenically transformed environment effects on the quantity of pharmaceutically valuable phenolic compounds in medicinal plants.

In vitro antioxidant activity of alginate nanoparticles encapsulating the aqueous extract of Coccinia grandis L.

Bioactive compounds in medicinal plants are more susceptible to preventing oxidative stress. Encapsulation of herbal extracts has empowered the properties and characteristics of bioactive compounds. Nanoencapsulation allows the enhancement of the stability of extracts and targeted drug delivery. The present study aims to determine the antioxidant activity of alginate nanoparticles encapsulating the aqueous extract of Coccinia grandis L. (Family: Cucurbitaceae). The aqueous extract of C. grandis (AqCG) was prepared by using ultrasonication (40 °C, 20 min, 40 kHz) followed by refluxing (2½ h). The prepared AqCG (1-5 mg/mL) encapsulated alginate nanoparticles were synthesized by ionic gelation with the addition of extracts and CaCl2. Characterization of nanoparticles was performed via encapsulation efficiency (EE%), loading capacity (LC%), particle size (PS), scanning electron microscopy (SEM), zeta potential and Fourier transform infrared (FTIR) spectroscopy analysis. The antioxidant activity of the nanoparticles was evaluated in vitro by the ferric reducing antioxidant (FRAP) assay, 2,2-di-phenyl-1-picrylhydrazyl (DPPH) radical scavenging assay and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging assay. One-way analysis of variance (ANOVA) followed by Tukey's posthoc test was used to analyze the data. Maximum LC% (3.07 ± 0.11) and average particle size (71 nm from SEM) were obtained for alginate nanoparticles encapsulated at 4 mg/mL extract concentration. The IC50 values for DPPH, ABTS, and FRAP were 6.49 ± 0.10 mg/mL, 0.24 ± 0.01 mg/mL, and 20.63 ± 0.28 mg Trolox equivalent/g of extract respectively for alginate nanoparticles encapsulating the AqCG. Nanoparticles have shown a significant difference in IC50 values compared to Trolox (p < 0.05). The successful encapsulation of the AqCG in the alginate matrix was evidenced by FTIR and SEM analysis. Encapsulation contributed to enhancing the antioxidant activity in terms of ABTS assay when compared to the AqCG. However, in vitro release and stability studies are warranted to facilitate the development of a commercially viable nanonutraceutical using alginate nanoparticles encapsulating the AqCG.
