Abstract:
In this study the chemical constituents of the higher polar sustances from Desmodium caudatum were investigated.The compounds were isolated by using column chromatographies over silicagel, polyamide, ODS, Sephadex LH-20, and preparative HPLC. The structures of these compounds were identified on the basis of NMR and MS spectra. Thirteen compounds were obtained and their structures were identified as vanillin(1), loliolide(2), indole-3-carboxaldehyde(3), salicylic acid(4), swertisin(5), saccharumoside C(6), isosinensin (7), kaempferol 3-O-β-D-glucopyranoside-7-O-α-L-rhamnopyranoside (8), isovitexin (9), vitexin (10), nothofagin(11), resveratroloside (12), and 2"-α-rhamnopyranosyl-7-O-methylvitexin (13). Except for compound 5, the remaining compounds were isolated from D. caudatum for the first time. Compounds 2, 3, 6-8, 11-13 were separated from the genus Desmodium for the first time.
