Abstract

Two new chalcones, 3,2',3'-trihydroxy-4'-methoxychalcone (1) and 3,2'-dihydroxy-4',6'-dimethoxychalcone (2), were isolated from the seeds of Clerodendrum phlomidis together with three known flavonoids, 5-hydroxy-7-methoxyflavanone (3), 5-hydroxy-7-methoxyflavone (4), and kaempferol-3-O-α-l-rhamnopyranoside (5). The structures of the new compounds 1 and 2 have been established mainly on the basis of 1D and 2D NMR studies.

摘要

从臭牡丹种子中分离得到两种新的查耳酮，即3,2',3'-三羟基-4'-甲氧基查耳酮（1）和3,2'-二羟基-4',6'-二甲氧基查耳酮（2），以及三种已知的黄酮类化合物，5-羟基-7-甲氧基黄烷酮（3）、5-羟基-7-甲氧基黄酮（4）和山柰酚-3-O-α-L-鼠李吡喃糖苷（5）。新化合物1和2的结构主要基于一维和二维核磁共振研究确定。
