麦冬中高异黄酮的分离与鉴定

ISOLATION AND IDENTIFICATION OF HOMOISOFLAVANONES FROM MAIDONG (OPHIOPOGON JAPONICUS (THUNB) KER-GAWL)

摘要: 从浙江产麦冬(Ophiopogon japonicus(Thunb)Ker-Gawl)的块根中分离出5个高异黄酮。通过理化性质和光谱分析鉴定了结构,其中3个是文献已报道的高异黄烷酮,即6-醛基异麦冬黄烷酮A(晶Ⅰ,6-aldehydo-isoophiopogonanone A),甲基麦冬黄烷酮B(晶Ⅱ,methylophiopogonanone B),甲基麦冬黄烷酮A(晶Ⅲ,methylophiopogonanone A),2个是新的高异黄酮,命名为6-醛基异麦冬黄酮B(晶Ⅳ,6-aldehydo-isoophiopogonone B)和6-醛基异麦冬黄酮A(晶Ⅴ,6-aldehydo-isoophiopogonone A)。

Abstract: Five homoisoflavonoids isolated from tubers of Ophiopogon japonicus (Thunb)Ker-Gawl cultivated in Zhejiang province were identified by means of physical and chemical properties and spectral data. Three are reported as known homoisoflavanones: 6-aldehydo-isoophiopogonanone A, methylophiopogonanone A and methylophiopogonanone B. Two are new homoisoflavones, named 6-aldehydoisoophiopogonone A and 6-aldehydo-isoophiopogonone B respectively.
