First Time

A new C-6 flavone glycoside (6), together with seven known compounds, cryptochlorogenic acid (1), chlorogenic acid (2), 2- O- trans-caffeoylhydrocitric acid (3), isovitexin 7-β-D-glucopyranoside (4), 7,4′-dihydroxy-5-methoxyflavone-6- C-β-D-glucopyranoside (5), 3,5- O-dicaffeoylquinic acid (7) and 4,5- O-dicaffeoylquinic acid (8), were isolated from the aerial parts of Knautia arvensis. Their structures were elucidated by extensive spectroscopic methods including 1D- (1H, 13C and TOCSY) and 2D-NMR (DQF-COSY, HSQC, HMBC) experiments, as well as ESIMS analysis. Compounds 1, 3-5 and 8 are reported for the first time in Knautia arvensis.

ABSTRACT Significantly fewer thraustochytrid protists (zoosporic fungi) were observed in association with healthy leaf tissue of the marine angiosperm Thalassia testudinum than in association with sterilized samples that were returned to the collection site for 48 h. In support of the hypothesis that sea grass secondary metabolites were responsible for these differences, extracts of healthyT. testudinum leaf tissues inhibited the growth of the co-occurring thraustochytrid Schizochytrium aggregatum and deterred the attachment of S. aggregatum motile zoospores to an extract-impregnated substrate. By using S. aggregatumfor bioassay-guided chemical fractionation, a new flavone glycoside was isolated and structurally characterized as luteolin 7-O-β-d-glucopyranosyl-2"-sulfate. Whole-leaf tissue concentrations of this metabolite (4 mg/ml of wet leaf tissue) inhibited S. aggregatum attachment, and a significantly lower concentration (270 μg/ml) reduced thraustochytrid growth by 50%, suggesting that natural concentrations are at least 15 times greater than that needed for significant microbiological effects. These results offer the first complete chemical characterization of a sea grass sulfated flavone glycoside and provide evidence that a secondary metabolite chemically defends T. testudinum against fouling microorganisms.

Both14C-clopyralid (3,6-dichloropicolinic acid) and14C-chlorsulfuron {2-chloro-N-[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)amino]carbonyl]benzensulfonamide} were readily absorbed by Canada thistle [Cirsium arvense(L.) Scop. ♯ CIRAR] leaves, with 99 and 75%, respectively, of the applied doses absorbed 144 h after application. Absorbed14C-clopyralid was rapidly exported from the treated leaves, whereas14C-chlorsulfuron was translocated much more slowly. After 144 h, 29% of the applied14C-clopyralid and 5% of the applied14C-chlorsulfuron were recovered in the roots and developing root buds of Canada thistle plants. Smaller amounts of the two herbicides were absorbed and translocated in perennial sowthistle (Sonchus arvensisL. ♯ SONAR) than in Canada thistle. More14C-clopyralid than14C-chlorsulfuron was absorbed and translocated out of treated leaves of perennial sowthistle, but equal amounts, 3 to 4% of the applied doses, were recovered in the roots and root buds 144 h after application. Foliar applications of clopyralid, followed by removal of the treated shoot 24, 72, or 144 h after application, markedly reduced shoot regrowth in both Canada thistle and perennial sowthistle. Similar treatment with chlorsulfuron did not prevent shoot regrowth in either species.

Sonchus arvensis L. leaves have been used traditionally to treat various disease conditions. This study is designed to evaluate cardioprotective potential of ethanol extract of S. arvensis leaves on isoproterenol-induced myocardial infarction in Wistar rat. Male Wistar albino rats were divided into three main groups: negative control (saline only), positive control (isoproterenol only), and S. arvensis extract treated groups. S. arvensis extract was administered in three doses; 50, 100, and 200 mg/kg b.w. p.o for 14 days. On day 13 and 14, isoproterenol (85 mg/kg bw) was given intraperitoneally to positive control and extract treated groups. The parameters studied were cardiac biomarker enzymes which were Creatine Kinase (CK), Creatine Kinase-MB (CK-MB), Aspartate Transaminase (AST), Alanine Transaminase (ALT) and Lactate Dehydrogenase (LDH). The results showed that S. arvensis at dose of 50 mg/kg b.w. could significantly (P<0.05) reduce the level of CK, CK-MB, AST, ALT, and LDH in myocardial infarcted rats compared to positive control. The increase of the dose of S. arvensis extract was not followed by an increase of its cardioprotective activity. In conclusion, Sonchus arvensis L. leaves extract at dose of 50 mg/kg b.w. has potential to be developed as cardioprotective drug.
