Fast determination of betaine in Lycii Fructus by ultra-performance convergence chromatography-tandem mass spectrometry

Over the past 2500 years, Lycii Fructus has been widely used as a functional food and tonic in Chinese herbal medicine. It can nourish the liver and kidneys, moisten the lungs, and improve eyesight. In this study, a new rapid and sensitive method has been developed for the quantitative determination of betaine (index compound) in Lycii Fructus by using ultra-performance convergence chromatography-tandem mass spectrometry (UPC2-MS). The separation of betaine was successfully achieved on an ACQUITY UPC2 BEH 2-EP column (150 mm×2.1 mm, 1.7 μm), with isocratic elution by a CO2-methanol (80:20, v/v) solvent at a flow rate of 0.7 mL/min. The conditions used in the separation process were as follows:modifier, 0.1% (v/v) formic acid in methanol; column temperature, 40℃; backpressure, 1.31×107 Pa; injection volume, 1 μL; and retention time, 3 min. The MS system was equipped with an electrospray ionization (ESI) ion source and operated in the selected ion recording (SIR) and positive ion mode. Under the abovementioned conditions, the calibration curve was obtained. The linear range of detection was 0.5-50.0 μg/mL, with a correlation coefficient of 0.9992, and the limit of detection (LOD) was found to be 0.013 μg/mL. The validity of the method was tested by analyses of precision, repeatability, stability, and accuracy (average recovery:96.3%). Finally, the developed method was applied to analyze 11 batches of samples. The results indicated that this method was suitable for evaluating the quality of Lycii Fructus.

Effects of health functional foods on Cytochrome P450 enzymes

Increasing evidence has shown the involvement of health functional foods (HFFs) in inhibition or induction of cytochrome P450 (CYP), affecting the pharmacokinetics of co-administered drugs. To optimize the use of HFFs, it is nec-essary to understand the effects of them on CYPs. In this review we summarize the findings from clinical and in vitro studies evaluating the effects of HFFs on CYPs. In in vitro studies, CYP2C9 and 3A4 were strongly inhibited by allicin in garlic, boswellia extract, fermented curcuma, licorice extract, pomegranate concentrate, and red yeast rice. Furthermore, CYP2C9 was suppressed by hydrolyzed soy extract, lycii fructus extract, and Rhus verniciflua extract. Moreover, red yeast rice strongly inhibited CYP2D6, whereas CYP 2C19 was strongly suppressed by garlic, licorice extract, lycii fructus extract, red yeast rice, and Rhus verniciflua extract. Meanwhile, ginkgo biloba leaf extract showed a potent inductive effect on CYP2C19. In clinical studies, the long-term consumption of ginseng or ginkgo biloba leaf extract caused moderate inductive effects on CYP3A, whereas intake of milk thistle extract led to a moderate inhibition of CYP2C9. Further clinical studies are needed to verify the effects of HFFs on CYPs.

Green synthesis of carbon dots functionalized silver nanoparticles for the colorimetric detection of phoxim

In this work, Lycii Fructus as raw materials for green synthesis of fluorescent carbon dots (CDs) reduce AgNO3. The CDs-AgNPs were synthesized by one-step method. CDs were applied to stabilize AgNPs due to abundant functional groups on the surface of CDs. In presence of phoxim, the dispersed CDs-AgNPs get aggregated and the absorption peak with red shift from 400 nm to 525 nm, resulting in the color changed from yellow to red. Under optimized conditions, the absorbance ratio at A525 nm/A400 nm was related linearly to the concentrations of phoxim in the range of 0.1–100 μM. The detection limit was calculated to 0.04 μM, which is lower than maximum residue limits of phoxim in samples in China. The colorimetric sensor was successfully utilized to monitoring phoxim in environmental and fruit samples with good recoveries ranges from 87% to 110.0%. These results showed the sensor had a promising application prospect in real samples.

A feasible and practical 1H NMR analytical method for the quality control and quantification of bioactive principles in Lycii Fructus

Lycii Fructus, a solanaceous drug, is widely used as functional foods and in Traditional Chinese Medicine. Samples collected from different regions of China have been found to be not identical in chemical compositions which might affect the biological activities. Although many chromatographic and spectrometric methods have been reported to determine the concentration of betaine and other bioactive amino acids, disturbance resulted from other polar substances with low UV-absorbance and expensive mass facilities reduced the applicability of these techniques. In the present study, the strong cation exchange solid phase extraction procedure incorporated with 1H NMR was successfully developed as a rapid and reliable method that can simultaneously determine betaine, citric acid, threonine, alanine, and proline in various Lycii Fructus. In addition, ERETIC 2 method based on PULCON principle was also applied and compared with conventional method. This feasible and practical method offers a very powerful tool for the quality control of commercial Lycii Fructus from different sources.

UPLC-MS/MS analysis for antioxidant components of Lycii Fructus based on spectrum-effect relationship

Lycii Fructus is widely cultivated in the Northwest China. It is well-known for its antiaging effect in traditional Chinese medicines (TCMs), but the effective components are not clear. In this work, the ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) was used to study the antioxidant components of Lycii Fructus through analyzing the spectrum-effect relationship, and the positive correlation components with antioxidant activity were partially identified. The extractums of Lycii Fructus were adsorbed with macroporous resin, and then eluted with water and 30%, 60%, 90% ethanol in turn. The extract fraction eluted with 60% ethanol was determined as the best, and was taken for subsequent experiments. With the above separation method, UPLC fingerprints of thirty batches of Lycii Fructus (from different areas) were obtained, and thirty common peaks were selected through similarity analysis (SA). Combined with the data of the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) assays, the spectrum-effect relationship was studied. The results showed that the main peaks with antioxidant activity were P14, P26, P8, and P21 for DPPH, and P26, P14, P21, and P19 for ABTS. Using the UPLC-MS/MS data, peaks P14, P19, P21, and P30 were respectively identified as chlorogenic acid, quercetin, kaempferol, and isorhamnetin, and then the results were confirmed through comparison with the standards and other references. Finally, their strong antioxidant activities were validated experimentally.

A Review of Three Commonly Used Herbs Which Enhance Memory and New Evidences Which Show Their Combination Could Improve Memory in Young Animals.

This review looks into the herbs Gingko biloba, Polygala tenuifolia, and Lycii fructus for their widely studied neuroprotective properties. In particular, we investigated memory enhancing effect of these herbs, and their potential synergetic effect on memory with new data. Sixmonth treated mice demonstrated shorter escape latency in water maze and shorter arrival time in a consolidated memory task. Immunochemistry showed evident increase in superoxide dismutase activities in the prefrontal cortex, implying protection against free radicals during aging. Discrete increase of catecholaminergic neurons was found in the prefrontal cortex, hippocampus, corpus striatum, and midbrain, suggesting better memory and better control on mood and behavior. Necrotic cells in the brain decreased as indicated by immunocytochemistry of lactic dehydrogenase. Terminal deoxynucleotidyl transferase dUTP nick end labeling showed no apoptotic cells in most brain areas in high dose group. Biochemistry revealed increase of dopaminergic cells in treatment groups at prefrontal cortex, and in the hippocampus and cerebellum of the high dose group. Most 6-month groups showed increase of serotonin in all three areas. For the high dose group, GABA increased in the hippocampus but not prefrontal cortex, which would help induce sleep at night. Protein kinase C increased in most groups at prefrontal cortex, hippocampus and cerebellum, signifying increase of possible signal transduction pathways for memory or other nervous activations. Our results intimate that the interaction of the three herbs exerts beneficial effects on memory, associated cognitive function, and necrosis. Future investigations based on the present data shall aid development of clinically relevant medication.

Green synthesis of carbon dots originated from Lycii Fructus for effective fluorescent sensing of ferric ion and multicolor cell imaging

Green, economical and effective method was developed for synthesis of fluorescent carbon dots (CDs), using one-pot hydrothermal treatment of Lycii Fructus. Optical and structural properties of the CDs have been extensively studied by UV–visible and fluorescence spectroscopic, x-ray diffraction (XRD) techniques, transmission electron microscopy (TEM) and high resolution TEM (HRTEM). Surface functionality and composition of CDs has been illustrated by Fourier transform infrared spectroscopy (FTIR), x-ray photoelectron spectroscopy (XPS) spectra and elemental analysis. The fabricated CDs possess stable fluorescent properties. The fluorescent quantum yield of the CDs can reach 17.2%. The prepared CDs emitted a broad fluorescence between 415 and 545nm and their fluorescence was tuned by changing excitation wavelength. Meanwhile, the fluorescence intensity of the CDs could be significantly quenched by Fe3+ (turn-off). The CDs exhibit captivating sensitivity and selectivity toward Fe3+ with a linear range from 0 to 30μM and a detection limit of 21nM. The prepared CDs were successfully applied to the determination of Fe3+ in the urine samples, the water samples from the from the Yellow River and living HeLa (Henrietta Lacks) cells. Moreover, the low-toxicity and excellent biocompatibility of the CDs were evaluated through MTT assay on HeLa cells. The CDs were also employed as fluorescent probes for multicolor imaging of HeLa cells successfully.

RAW REHMANNIA RADIX POLYSACCHARIDE CAN EFFECTIVELY RELEASE PEROXIDATIVE INJURY INDUCED BY DUCK HEPATITIS A VIRUS.

Background:Duck viral hepatitis (DVH), caused by duck hepatitis A virus (DHAV), is a fatal contagious infectious disease which spreads rapidly with high morbidity and high mortality, and there is no effective clinical drug against DVH.Materials and Methods:Raw Rehmannia Radix Polysaccharide (RRRP), Lycii Fructus polysaccharides and Astragalus Radix polysaccharides were experimented in vitro and in vivo. Mortality rate, livers change, liver lesion scoring, peroxidative injury evaluation indexes in vitro and in vivo, and hepatic injury evaluation indexes of optimal one were detected and observed in this experiment.Results:RRRP could reduce mortality with the protection rate about 20.0% compared with that of the viral control (VC) group, finding that RRRP was the most effective against DHAV. The average liver scoring of the VC, blank control (BC), RRRP groups were 3.5, 0, 2.1. Significant difference (P<0.05) appeared between any two groups, demonstrating that it can alleviate liver pathological change. RRRP could make the hepatic injury evaluation indexes similar to BC group while the levels of the VC group were higher than other two groups in general. The levels of SOD, GSH-Px, CAT of RRRP group showed significant higher than that of VC group while the levels of NOS and MDA showed the opposite tendency, thus, RRRP could release peroxidative injury.Conclusion:RRRP was the most effective against duck hepatitis A virus (DHAV). RRRP could reduce mortality, alleviate liver pathological change, down-regulate liver lesion score, release peroxidative injury and hepatic injury. The antiviral and peroxidative injury releasing activity of RRRP for DHAV provided a platform to test novel drug strategies for hepatitis A virus in human beings.

Chinese materia medica used in medicinal diets

Ethnopharmacological relevanceMedicinal diets have a history of more than 2000 years. Locally referred to as yaoshan (Chinese: 药膳), a medicinal diet is understood in China as a dietary product that combines herbs and food with the purpose of preventing and treating diseases or improving health under the guidance of traditional Chinese medicine theory. Medicinal diets are used in Chinese people's daily life and in specialized restaurants. Hundreds of Chinese materia medica (CMM) are used in medicinal diets; however, a comprehensive evaluation of medicinal diets is lacking. Aims of the studyThis is an exploratory study that aims to identify the CMM that are most frequently used in medicinal diets and to provide an updated view of the current situation of medicinal diets in China. Materials and methodsA field study of 1221 people in 32 Chinese provinces was conducted over a period of approximately 6 months and included various types of interviews as well as a written questionnaire. Two approaches were used to analyse the data collected in the survey: (1) estimating the frequency of CMM consumed in daily diets; and (2) collecting CMM used in medicinal diet restaurants. Complementary information on the selected CMM was obtained from relevant databases, including PubMed, Google Scholar, Baidu Scholar, CNKI, and Web of Science. ResultsTen CMM were reported as commonly used by more than 50% of the participants. Among these 10 species, most medicinally used parts were seeds and fruits. Pharmacological data from the literature revealed that these species are associated with a wide spectrum of biological properties, including antitumour (80%), antioxidant (50%), anti-diabetic (40%), antilipemic (40%), anti-aging (40%), antimicrobial (40%) and cardioprotective (40%) activities. Our survey shows that most medicinal diet restaurants are located in the eastern part of China, with the greatest numbers being found in Beijing and Guangzhou. Only Dioscoreae Rhizoma, Lycii Fructus, Chrysanthemi Flos and Longan Arillus were frequently consumed both in daily diets and at medicinal diet restaurants. Some of the similarities shared by these 4 species include an extensive history of use (>2000 years); a sweet flavour; and antioxidant, antidiabetic, antilipemic and cardioprotective effects. ConclusionsThe 10 most commonly consumed CMM possess various biological effects that are currently target the most frequent health problems for the majority of the population. The development of medicinal diet restaurants has certain regional restrictions and is associated with the local climate environment and dietary culture. The data revealed by this study provided useful information for commercial exploitation of medicinal diets and their components and serve as a basis for further studies on various aspects of medicinal diets.

ObjectiveTraditional Chinese medicines (TCMs) as natural therapeutic agents have been widely used and received great attention over the world. However, the information on them to cause herb-drug interactions mediated by cytochrome P450 (CYP) enzymes is limited. The present study aims to evaluate the inhibitory effects of 11 commonly used TCMs, including Nelumbinis Folium, Ginseng Radix et Rhizoma, Ziziphi Spinosae Semen, Chrysanthemi Flos, Lonicera Japonica Flos, Lycii Fructus, Cassiae Semen, Poria, Crataegi Fructus, Schisandrae Chinensis Fructus, and Polygonati Rhizoma, on the five human major CYP isoenzymes 2C19, 2D6, 3A4, 2E1, and 2C9. MethodsAn in vitro cocktail method was used. ResultsThe aqueous extracts of all tested TCMs were found no significant inhibitory effect, with IC50 values higher than 100 μg/mL. While, the ethanolic extracts of some herbs showed more potent inhibition. These herbs include Nelumbinis Folium with IC50 values of 12.05 and 61.43 μg/mL on CYP2D6 and CYP2E1, Schisandrae Chinensis Fructus with IC50 values of 64.42 and 47.24 μg/mL on CYP2C19 and CYP3A4, and Chrysanthemi Flos with IC50 values of 45.25 μg/mL on CYP2C9, respectively. ConclusionCo-administration of these TCMs and their products with conventional medicines should be paid much attention to, and their potential inhibitory effects on CYP enzyme activities need to be further investigated.

Rapid Analysis of Corni fructus Using Paper Spray-Mass Spectrometry.

Paper spray-mass spectrometry (PS-MS) is a kind of ambient MS technique for the rapid analysis of samples. Corni fructus has been widely used in traditional Chinese compound preparations and healthy food. However, a number of counterfeits of Corni fructus, such as Crataegi fructus, Lycii fructus, and grape skin are illegally sold in crude herb markets. Therefore, the development of a rapid and high-throughput quality evaluation method is important for ensuring the effectiveness and safety of the crude materials of Corni fructus. To develop PS-MS chemical profiles and a semi-quantitative method of Corni fructus for quality assessment and control, and species distinction of Corni fructus. Both positive and negative ion PS-MS chemical profiles were constructed for species distinction. The statistical analysis of the chemical profiles was accomplished by principal component analysis (PCA). Rapid semi-quantitative analysis of loganin and morroniside in the extracts of Corni fructus were accomplished by PS-MS. The profiles of the Corni fructus and Crataegi fructus samples were clearly clustered into two categories. The limit of quantification (LOQ) in the semi-quantitative analysis was 6μg/mL and 5.6μg/mL for loganin and morroniside, respectively. PS-MS is a simple, rapid, and high-throughput method for the quality control and species distinction of Corni fructus. Copyright © 2017 John Wiley & Sons, Ltd.
