Abstract

A study of the chemical constituents of a methanolic extract of the roots of Livistona halongensis (Arecaceae) led to the isolation of two new flavanes, 2S,3S-3,5,7,3'-tetrahydroxy-5'-methoxyflavane (1) and 3,7,3'-trihydroxy-5'-methoxyflavane 5-O-beta-glucopyranoside (2), together with trans-3,5,3',5'-tetrahydroxy-4-methoxystilbene, saccharose and beta-sitosterol-3-O-beta-glucopyranoside. The structures of these compounds were elucidated on the basis of spectroscopic data.

摘要

对哈龙湾蒲葵（棕榈科）根部甲醇提取物的化学成分进行研究，从中分离出两种新的黄烷，即2S,3S - 3,5,7,3'-四羟基 - 5'-甲氧基黄烷（1）和3,7,3'-三羟基 - 5'-甲氧基黄烷5 - O-β-葡萄糖吡喃糖苷（2），以及反式 - 3,5,3',5'-四羟基 - 4 - 甲氧基芪、蔗糖和β-谷甾醇 - 3 - O-β-葡萄糖吡喃糖苷。这些化合物的结构通过光谱数据得以阐明。
