Diastereoisomeric saponins from Albizia julibrissin
摘要:
The structures of four new diastereoisomeric triterpenoidal saponins Julibroside J(5), J(8), J(12) and J(13) (1-4) isolated from Albizia julibrissin Durazz. (Leguminosae) have been determined on the basis of comprehensive spectroscopic analysis and chemical degradation. Julibroside, J(8) and J(13) showed marked cytotoxic activities against Bel-7402 cancer cell line at 100 mu g/mL. (c) 2005 Elsevier Ltd. All rights reserved.

7-octadienyl]oxy]-16-hydroxy -3-[[O-beta-D-xylopyranosyl-(1 --> 2)-O-alpha-L-arabinopyranosyl-(1 --> 6)-2-(acetylamino)-2-deoxy-beta-D-glucopyranosyl]oxy]-(3beta,16alpha,21beta)-olea n-12-en-28-oic acid O-alpha-L-arabinofuranosyl-(1 --> 4)-O-[beta-D-glucopyranosyl-(1 --> 3)]-O-6-deoxy-alpha-L-mannopyranosyl-(1 --> 2)-beta-D-glucopyranosyl ester (1). The hemolytic potential of 1 was evaluated using in vitro assays, and
Four new triterpenoidal saponins, called calliandra saponins B (8), C (9), D (10), and F (12), were isolated from the branches of Calliandra anomala (KUNTH) MACBR. The structures of these compounds were established on the basis of NMR spectra, FAB-MS, and the chemical evidence.These saponins, interestingly, have a N-acetyl glucosamine at the 3 position of the genin, and one or two monoterpene glycosides at the position of the sugar chain.
根据核磁共振波谱、FAB-MS 和化学证据确定了四种新的三萜类皂苷,即 Calliandra 皂苷 B (8)、C (9)、D (10) 和 F (12)。有趣的是,这些皂苷在基因素的 3 位上有一个 N-乙酰氨基葡萄糖,在糖链的位置上有一个或两个单萜苷。
