This is the first report of a phytochemical investigation of Jamaican populations of a local folk medicinal plant Salvia coccinea (Lamiaceae/Labiatae). Apart from the presence of β-sitosterol, phytochemical profiling of the aerial parts yielded compounds other than those previously reported from Indian and Italian populations. The triterpenes betulinic acid and betulin, the phytosterols β-sitosterol and β-sitosterol-3- O-β-D-glucopyranoside, as well as the steroid precursor squalene were isolated. The structures of the compounds were established by comparison of NMR spectroscopic data with those reported in literature.

Seven flavonoids were isolated from the butanol fraction of the methanolic extract of the aerial parts of Cynanchum acutum L. (Asclepiadaceae). All of which have been isolated for the first time from the genus Cynanchum. Their structures were established as quercetin 3-O-β-galacturonopyranoside (1), quercetin 7-O-β-glucopyranoside (2), tamarixtin 3-O-β-galacturonopyranoside (3), kaempferol 3-O-β-galacturonopyranoside (4), 8-hydroxyquercetin 3-O-β-galactopyranoside (5), tamarixtin 3-O-α-rhamnopyranoside (6), and tamarixtin 7-O-α-arabinopyranoside (7) on the basis of their chromatographic properties, chemical and spectroscopic data. The major isolated flavonoids 1, 2 and 3 were found to exhibit significant antioxidant and antidiabetic activities (by measuring blood glucose and insulin levels). This is the first report about the antioxidant and antidiabetic activities of compounds 1 - 3.

Schleichera oleosa (Lour.) Oken. is a medicinal plant of Bangladesh with enormous traditional applications in folk medicine. The current study was designed to isolate the secondary metabolites by successive chromatographic separation of n-hexane and dichloromethane soluble fractions of a methanol extract of leaves of S. oleosa. A total of four compounds were separated and identified as 5,7-dihydroxy-4'-methoxyflavone, stigmasterol, lupeol and betulinic acid. The structures of the isolated compounds were elucidated by analysis of their 1H NMR data and comparison with published values. Bangladesh Pharmaceutical Journal 24(1): 33-36, 2021

From the aerial parts of Hypericum laricifolium Juss., twelve compounds were isolated and identified. They were the xanthones: 1-hydroxy-7-methoxy-xanthone (1), 1,7-dihydroxy-xanthone (2), 2-hydroxy-xanthone (3), 6-deoxyisojacareubin (4), 1,3-dihydroxy-6-methoxy-xanthone (6), and 1,5,6-trihydroxy-7-methoxy-xanthone (7), together with β-sitosterol, betulinic acid, vanillic acid, isoquercitrin and a mixture of quercetin and isorhamnetin. All the compounds were characterized by spectroscopic and mass spectrometric methods, and by comparison with literature data. Thisis the first report on the presence of xanthones in H.laricifolium. 1,3-Dihydroxy-6-methoxy-xanthone has been previously synthesized, but this is the first report of its isolation from a natural source.

Bistorta manshuriensis is a well-known Korean medicinal plant traditionally used to treat diarrhea. Phytochemical investigation of the aerial parts of B. manshuriensis led to the isolation of two new feruloyl sucrose derivatives, bistoroside A (1) and bistoroside B (2), together with three known compounds, helonioside A (3), helonioside B (4), and smilaside L (5). The structures of the new compounds were elucidated as (3,6-di-O-Z-feruloyl)-β-D-fructofuranosyl-(1→2)-α-D-glucopyranoside (1) and (3,6-di-O-Z-feruloyl)-β-D-fructofuranosyl-(1→2)-(6′-O-acetyl)-α-D-glucopyranoside (2) on the basis of extensive analysis of 1D and 2D NMR (HMQC and HMBC), HR-FAB-MS, and chemical evidence.

Abstract Cannabis sativa is a millenary medicinal plant. However, contrary to worldwide paradigm-shifting, countries like Brazil still prohibit C. sativa cultivation and its medicinal use, even though many populations use aerial parts and roots of this plant for healthcare. As such, the objective of this work was to identify substances in the samples of the C. sativa roots, tracing a correlation with antitussive and expectorant effects. Therefore, samples of C. sativa roots were donated by the Polícia Federal Brasileira, and its aqueous extract (AECsR) was prepared with subsequent lyophilization, to maintain the material stability. After that, the material was analyzed by LC-MS to observe its chemical profile. Four samples (AECsR-A, B, C, and D) were tested in animal models of citric acid-induced cough (0.4 M) and phenol red expectoration (500 mg/kg). Using LC-MS it was possible to identify 5 molecules in C. sativa roots: p-coumaroyltyramine, tetrahydrocannabinol-C4, feruoiltyramine, anhydrocanabisativine, and cannabisativine. In experimental protocols, male mice (Mus musculus) were treated with samples of AECsR at doses of 12.5, 25, or 50 mg/kg regardless of the pharmacological test. In these tests, all samples showed the potential to treat cough and promote fluid expectoration, differing only in the dose at which these effects were observed. Therefore, the data showed that the C. sativa roots of the Brazilian Northeast showed antitussive and expectorant effects, even with intense secondary metabolitesʼ variation, which alters its potency, but not its effect. This highlights the importance of this medicinal plant for future therapy and corroborates to traditional use.

Objective: The aim of this research was to isolate and identify flavonoids extracted from the leaves of Moricandia arvensis.Methods: The phytochemical screening reaction and thin-layer chromatography have been used to characterize the chemical groups, before they were identified by nuclear magnetic resonance.Results: The leaves contain essentially flavonoids, tannins, cardenolides, saponins, and alkaloids. The phytochemical investigation of the water-acetone extract led to the isolation of five flavonoids derivatives, namely: 5,7-dihydroxy-3,6,4’-trimethoxyflavone (1); 5,7,4’-trihydroxy- 3,6,8,3’-tetramethoxyflavone (2); 3,3’,4’, 5,7- pentahydroxy flavanone (3); 3-glucosyl 3’,4’,5,7 tetrahydroxy flavonol (4); and kaempférol-3- digalactopyranoside (5). The structures of 1–5 were identified by comparison of their spectral data with those reported in the literature.Conclusion: In this work, it was possible to isolate and identify five flavonoids after fractionation of the hydroacetone extract from the leaves of the medicinal plant M. arvensis.
