Lespedeza cuneata, belonging to Fabaceae, is well-known as Chinese bushclover, and it has been used in traditional folk medicines for the treatment of disorders, such as diabetes, hematuria, and insomnia. As part of continuing research projects to discover interesting natural compounds with biological activities from Korean medicinal plants, the phytochemical investigation of L. cuneata resulted in the isolation of five chemical constituents: α-tocopherol (1), 7a-methoxy-α-tocopherol (2), 13(R)-hydroxy-octadeca-(9Z,11E,15Z)-trien-oic acid (3), α-dimorphecolic acid (4), and lupeol (5). The structural determination of the isolated compounds was elucidated from data gathered through nuclear magnetic resonance (NMR) spectroscopy and liquid chromatography–mass spectrometry (LC/MS). Until now, this study is the first to report these five compounds from the plant L. cuneata. Moreover, these isolated compounds (1–5) were evaluated for their anti-adipogenesis effects and their role in lipid metabolism during adipocyte maturation. As a result, the upregulation of mRNA expression levels of Fabp4 from 3T3-L1 pre-adipocytes treated with compounds 3 and 4 demonstrated that these compounds efficiently induced adipocyte differentiation. Furthermore, compounds 3 and 4 were found to regulate lipid metabolism by the induction of lipolytic and of lipogenic gene expressions. Therefore, experimental data from these findings supported that the compounds 3 and 4 induce the adipogenesis of 3T3-L1 pre-adipocytes and regulate lipid metabolism.

Monotheca Buxifolia

Abstract Background Ethnobotanical and plant-based products allow for the isolation of active constituents against a number of maladies. Monotheca buxifolia is used by local communities due to its digestive and laxative properties, as well as its ability to cure liver, kidney, and urinary diseases. There is a need to explore the biological activities and chemical constituents of this medicinal plant. Methods In this work, the biochemical potential of M. buxifolia (Falc.) A. DC was explored and linked with its biological activities. Methanol and chloroform extracts from leaves and stems were investigated for total phenolic and flavonoid contents. Ultrahigh-performance liquid chromatography coupled with mass spectrometry (UHPLC–MS) was used to determine secondary-metabolite composition, while high-performance liquid chromatography coupled with photodiode array detection (HPLC–PDA) was used for polyphenolic quantification. In addition, we carried out in vitro assays to determine antioxidant potential and the enzyme-inhibitory response of M. buxifolia extracts. Results Phenolics (91 mg gallic-acid equivalent (GAE)/g) and flavonoids (48.86 mg quercetin equivalent (QE)/g) exhibited their highest concentration in the methanol extract of stems and the chloroform extract of leaves, respectively. UHPLC–MS analysis identified a number of important phytochemicals, belonging to the flavonoid, phenolic, alkaloid, and terpenoid classes of secondary metabolites. The methanol extract of leaves contained a diosgenin derivative and polygalacin D, while kaempferol and robinin were most abundant in the chloroform extract. The methanol extract of stems contained a greater peak area for diosgenin and kaempferol, whereas this was true for lucidumol A and 3-O-cis-coumaroyl maslinic acid in the chloroform extract. Rutin, epicatechin, and catechin were the main phenolics identified by HPLC–PDA analysis. The methanol extract of stems exhibited significant 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical-scavenging activities (145.18 and 279.04 mmol Trolox equivalent (TE)/g, respectively). The maximum cupric reducing antioxidant capacity (CUPRAC) (361.4 mg TE/g), ferric-reducing antioxidant power (FRAP) (247.19 mg TE/g), and total antioxidant potential (2.75 mmol TE/g) were depicted by the methanol extract of stems. The methanol extract of leaves exhibited stronger inhibition against acetylcholinesterase (AChE) and glucosidase, while the chloroform extract of stems was most active against butyrylcholinesterase (BChE) (4.27 mg galantamine equivalent (GALAE)/g). Similarly, the highest tyrosinase (140 mg kojic-acid equivalent (KAE)/g) and amylase (0.67 mmol acarbose equivalent (ACAE)/g) inhibition was observed for the methanol extract of stems. Conclusions UHPLC–MS analysis and HPLC–PDA quantification identified a number of bioactive secondary metabolites of M. buxifolia, which may be responsible for its antioxidant potential and enzyme-inhibitory response. M. buxifolia can be further explored for the isolation of its active components to be used as a drug.

ABSTRACT This study aimed to evaluate the antifungal activity of methanol extract and fractions of leaves of Randia nitida (Kunth) DC on Colletotrichum truncatum (Schw.) Andrus & Moore, Rhizoctonia solani Kühn and Sclerotinia sclerotiorum (Lib.) De Bary and perform chemical and antioxidant activity tests. Crude methanol extract (EBM) and fractions (hexane = FHX, dichloromethane = FDM and ethyl acetate = FAE) underwent classical phytochemical analysis and determination of total phenols, flavonoids and antioxidant activity. Samples were individually incorporated into PDA culture mediums (potato-dextrose-agar) at concentrations of 10, 20, 40, 80 and 160 µg mL-1 of extract or fraction. Mycelial growth was evaluated when control reached the edge of the plate. Phytochemical results indicated that flavonoids, steroids and triterpenoids are the major chemical constituents in both EBM and fractions. Total phenols, flavonoids and antioxidant activity were higher for FAE and EBM, followed by FDM and FHX; however, the latter showed higher content of steroids and triterpenoids compared to the other fractions. For C. truncatum, R. solani and S. sclerotiorum, the most efficient fractions were respectively FAE, FDM and FHX, all of them in the highest concentration (160 µg mL-1). The highest inhibition rate was observed against S. sclerotiorum, reaching 93.75%. We concluded that all fractions have antifungal activity on the plant pathogens, being FHX the most active against S. sclerotiorum, which might have been due to the presence of steroids and triterpenes.

Abstract The present study was designed to identify the chemical constituents of the methanolic extract of Curcuma longa L. rhizomes and their inhibitory effect on a hepatoma cell line. The methanolic extract was subjected to GC-MS analysis to identify the volatile constituents and the other part of the same extract was subjected to liquid column chromatographic separation to isolate curcumin. The inhibition of cell growth in the hepatoma cell line and the cytopathological changes were studied. GC-MS analysis showed the presence of fifty compounds in the methanolic extract of C. longa. The major compounds were ar-turmerone (20.50 %), β-sesquiphellandrene (5.20 %) and curcumenol (5.11 %). Curcumin was identified using IR, 1H and 13C NMR. The inhibition of cell growth by curcumin (IC50 = 41.69 ± 2.87 μg mL-1) was much more effective than that of methanolic extract (IC50 = 196.12 ± 5.25 μg mL-1). Degenerative and apoptotic changes were more evident in curcumin- treated hepatoma cells than in those treated with the methanol extract. Antitumor potential of the methanolic extract may be attributed to the presence of sesquiterpenes and phenolic constituents including curcumin (0.051 %, 511.39 μg g-1 dried methanol extract) in C. longa rhizomes.

According to traditional medicinal texts as well as modern research, Rubia cordifolia (Desi Manjistha) stem cure various diseases of blood, skin diseases, inflammations, kidney stones, fever and various Kapha disorders. However, stems of Rubia cordifolia (Desi Manjistha) are often adulterated with stems of Rubia tinctorum (Irani Manjistha) due to morphological similarity. This adulteration is extremely harmful as R. tinctorum has Lucidin as one of the chemical constituents, which has severe genotoxic effects. The present work focuses on developing a comparative HPTLC fingerprint and GC-MS analysis of R. cordifolia and R. tinctorum, so as to detect the adulteration by R. tinctorum in R. cordifolia raw material form and in formulations. Methanol extracts of the individually powdered stems were used to develop a suitable mobile phase, such that a clear spot was obtained in TLC of R. tinctorum but not in TLC of R. cordifolia using the same mobile phase. This mobile phase was further used to develop a comparative HPTLC fingerprint of the two species. Methanol extracts of R. cordifolia and R. tinctorum were used for investigation of phytoconstituents by GC-MS analysis. The mobile phase n-butanol: ethanol (6:4) was the one which gave a clear single spot at Rf 0.89 in TLC of methanol extract of R. tinctorum but not in TLC of methanol extract of R. cordifolia, at 254nm and 366nm. Further, HPTLC analysis gave results clearly differentiating the two species using the same mobile phase. Further, GC-MS analysis of R. cordioflia revealed the presence of 9 phytoconstituents while R. tinctorum revealed the presence of 6 phytoconstituents, which are different from each other. Thus, these simple yet sophisticated techniques will be very useful for herbal industry in standardization and detection of adulteration of R. tinctorum in R. cordifolia formulations, thereby benefitting the patients who consume Manjistha formulations.
