紫桑椹果中非营养成分的分析

Quantitative Analysis of non-Nutritional components in Black Mulberry

研究浙江果桑“大十”品种白藜芦醇、原花青素和类胡萝卜素的成分及含量。用高效液相色谱法一铁盐催化比色法对三种非营养成分作了分析。实验结果为紫桑椹果中自藜芦醇含量在4．19—6．09μg／g、原花青素含量46．0～49．8mg／g；类胡萝卜素含量0．703—1．197μg/g；而桑叶不含白藜芦醇，原花青素测得值仅为0．522～0．536mg／g。桑椹含有丰富的天然活性物质，为合理利用桑椹资源及进一步开发研究提供了科学依据。

To recognize the components and contents of resveratrol ,procyanidins and carotenoids in mulberry of ＂Dashi＂ in Zhejiang,the three nonnutritional components were analyzed by HPLC-Colorimetry with ferric ions as catalysis agent. Contents of resveratrol, procyanidins and carotenoids were 4.19-6.09 μg/g,46.0-49.8 mg/g and 0.703-1. 197 μg/g respectively in black mulberry. There was no resveratrol in mulberry leaves and the content of procyanidins was 0. 522- 0. 536 mg/g. The mulberry contains natural active substances provides scientific basis for the rational use ,further exploitation and study of the mulberry resources.
