采用超声提取和HPLC测定栽培植株与野生植株桃儿七不同部位中4’-去甲基鬼臼毒素和鬼臼毒素的含量,结果表明,栽培植株各部位4’-去甲基鬼臼毒素含量依次为叶柄>根,叶中未检测到此物质,野生植株不同部位4’-去甲基鬼臼毒素含量依次为须根>茎>根状茎>叶,果实中未检测到此物质;栽培植株和野生植株不同部位鬼臼毒素含量均为根>茎>叶(>果实);桃儿七栽培植株各部位2种木脂素含量随季节变化呈W型,以7月份采收时含量最高。
The content of 4’-demethylation podophyllotoxin and podophyllotoxin in seven different parts of cultivated plants and wild plants were determined by ultrasonic extraction and HPLC. The results showed that the content of 4’-demethyl podophyllotoxin Followed by the petiole> root, the leaf is not detected in this material, wild plants in different parts of 4’-demethyl podophyllotoxin were fibrous roots> stem> rhizome> leaves, the fruit is not detected in the material; cultivated plants And podophyllotoxin content in different parts of wild plants were root> stem> leaf (> fruit). The contents of two kinds of lignans in different parts of peach seven cultivars were W-shape with the change of seasons, and the content of podophyllotoxin was the highest when harvested in July.
