This research was designed to isolate pinostrobin from Kaempferia pandurata Roxb. rhizome using a chromatography method and to study its structural modification through ethylation and allylation reactions. Two compounds were afforded from the ethylation reaction that were 5-ethoxy-7-methoxyflavanone and 4′-ethoxy-6′-methoxychalcone and in the case of the allylation, 5-O-allylpinostrobin (5-allyloxy-7-methoxyflavanone) and 6-allylpinostrobin (6-allyl-5-hydroxy-7-methoxyflavanone) were obtained.

蓬松根茎中松醚酯的乙基化和烯丙基化反应

本研究旨在从山柰中分离松菌素。使用色谱方法研究根茎，并通过乙基化和烯丙基化反应研究其结构修饰。从乙基化反应中得到两种化合物，即 5-乙氧基-7-甲氧基黄烷酮和 4'-乙氧基-6'-甲氧基查尔酮，在烯丙基化的情况下，得到 5-O-烯丙菌酯（5-烯丙氧基-7-甲氧基黄烷酮）和获得6-烯丙菌酯(6-烯丙基-5-羟基-7-甲氧基黄烷酮)。
