Antibacterial activity of a triterpenoid saponin from the stems of Caesalpinia pulcherrima Linn.

A new compound 1 was isolated from the methanolic extract of the stems of the Caesalpinia pulcherrima Linn. along with a reported compound (2) 3-O-β-D-glucopyranosyl-(1→4)-β-D-xylopyranosyl-(1→3)-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranosyl hederagenin 28-O-β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl ester. The new compound 1 has m.p. 272–274°C, m.f. C46H74O17, [M]+ m/z 898. It was characterised as 3-O-β-D-glucopyranosyl-(1→4)-α-L-arabinopyranosyl hederagenin 28-O-β-D- xylopyranosyl ester by various colour reactions, chemical degradations and spectral analyses. Antibacterial activity of compound 1 was screened against various Gram-positive and Gram-negative bacteria and showed significant results.

Microwave-accelerated methylation of starch

A novel microwave-accelerated method for methylating soluble starch is described. Soluble starch could be fully methylated in 72% yield within 4.66 min using iodomethane and 30% potassium hydroxide under microwave irradiation. The completely methylated starch thus obtained was hydrolyzed with 60% HCO2H for 1.5 min under 80% MW power, followed by 0.05 M H2SO4 for 2.0 min under 100% MW power. The partially methylated monosaccharides were separated by preparative paper chromatography and identified by their melting points and optical rotations.

New Phenolic Components from Dalbergia Volubilis

Phytochemical examination of non green branches of Dalbergia volubilis on extensive column and preparative thin layer chromatography yielded twelve compounds eight of which are already known compounds and were identified as sitosterol, 7-hydroxy-4-methyl-coumarin, dalbergin, biochanin-A, umbelliferone, p-hydroxy cinnamic acid, kaempferol and quercetin-3-O-glucoside.The other four compounds were new natural products, three of which were identified as novel 4-phenyl-2H-1-benzopyran-2-ones while the fourth one was a new 12a-hydroxy rotenoid.The structure of these new compounds has been established on the basis of chemical and spectral evidences and through derivatization, as 4',7-dihydroxy-3'-methoxy-4-phenyl-2H-1-benzopyran-2-one, 3',7-dihydroxy-4',5-dimethoxy-2H-1-benzopyran-2-one, 3',7-dihydroxy4',5-dimethoxy-6-formyl-2H-1-benzopyran-2-one and a complex rotenoid determined to be as (VII).The co-occurence of 4-methyl-2H-1-benzopyran-2-ones, 4-phenyl-2H-1-benzopyran-2-ones, isoflavones and rotenoids is of interest from biogenetic considerations.
