Abstract

From the bark of Uncaria guianensis, two new quinovic acid glycosides, quinovic acid 3 beta-O-beta-D-quinovopyranoside and quinovic acid 3 beta-O-beta-D-fucopyranosyl-(27----1)-beta-D-glucopyranosylester, have been isolated, in addition to known quinovic acid 3 beta-O-[beta-D-glucopyranosyl-(1----3)-beta-D-fucopyranosyl]-(27----1)- beta-D-glucopyranosylester and quinovic acid 3 beta-O-beta-D-fucopyranoside. Their structures were elucidated by spectral and chemical studies.

摘要

从圭亚那钩藤的树皮中，除了已知的奎诺酸3β-O-[β-D-吡喃葡萄糖基-(1→3)-β-D-吡喃岩藻糖基]-(27→1)-β-D-吡喃葡萄糖酯和奎诺酸3β-O-β-D-吡喃岩藻糖苷外，还分离出了两种新的奎诺酸糖苷，即奎诺酸3β-O-β-D-吡喃鸡纳糖基苷和奎诺酸3β-O-β-D-吡喃岩藻糖基-(27→1)-β-D-吡喃葡萄糖酯。通过光谱和化学研究阐明了它们的结构。
