Abstract A new dihydrochalcone derivative, lusianin, two other known chalcones and a phenanthrene derivative were isolated from the orchid Lusia volucris. The two chalcones and the phenanthrene derivative were characterized as 2-propene-1-one-1-(2′,4′-dihydroxy-3′-methoxyphenyl)-3-(4″-methoxyphenyl) and 2-propene-1-one-1-(2′-hydroxy-4′-methoxyphenyl)-3-(4″-methoxyphenyl) and 6-hydroxy-2,4,7-trimet
摘要 从兰花中分离得到了一种新的二氢查尔酮衍生物lusianin、另外两种已知的查耳酮和一种菲衍生物。两种查耳酮和菲衍生物的特征为 2-propene-1-one-1-(2',4'-dihydroxy-3'-methoxyphenyl)-3-(4″-methoxyphenyl) 和 2-propene-1- one-1-(2'-羟基-4'-甲氧基苯基)-3-(4″-甲氧基苯基)和 6-羟基-2,4,7-三甲氧基菲(batatasin-I),分别通过独立光谱分析化合物及其乙酰衍生物。根据光谱和化学证据确定 lusianin 的结构为 1-propanone-1-(2',4'-dihydroxy-3'-methoxyphenyl)-3-(4″-methoxyphenyl)。
