179种植物叶中β-胡萝卜素含量分析

Determination of β-carotene Contents in Leaves of 179 Plants

为探索新的植物β-胡萝卜素,采用纸层析法对分属52科的179种亚热带植物鲜叶中的β-胡萝卜素含量进行了分析。结果表明:β-胡萝卜素含量低于20.0mg/kg的植物有69种,介于20.0～50.0mg/kg的植物有88种,高于50mg/kg的植物22种;在52科植物中,竹亚科和壳斗科植物叶中β-胡萝卜素含量较高,其中含量最高的是板栗,为67.75mg/kg,具有较高的研究和开发价值。

To explore new plant β-carotene, the content of β-carotene in leaves of 179 species belonging to 52 families in subtropical China were determined by paper chromatography. In 69 species, β-carotene contents were less than 20.0 mg/kg. In 88 species,contents were 20.0-50.0 mg/kg. In 22 species, contents were higher than 50 mg/kg. The contents in families of Bambuseae and Fagaceae were higher than other families, in which the content of Castanea mollissima was the highest, which was 67.75 mg/kg, having high value of research and exploitation.
