芒果树不同植株部位的芒果苷含量比较

Comparison of Mangiferin Contents in Different Parts of Mango Tree

目的:比较芒果树不同植株部位的芒果苷含量。方法:采用RP-HPLC法对芒果树的根、树干、皮、叶、枝条等部位进行芒果苷含量测定。结果:嫩芽、嫩叶、落叶、绿皮嫩枝、芒果成熟果实的芒果苷含量与成熟叶的芒果苷含量相当;花、树干、树根和粗树枝中的芒果苷含量远低于成熟叶,而芒果青果的芒果苷含量远高于成熟叶。结论:芒果树不同植株部位的芒果苷含量不同。

Objective：To compare the mangiferin contents in different parts of mango tree. Methods：Mangiferin contents in root, stem, bark, leaf, branch of mango tree were determinated by HPLC. Results： Mangiferin contents in bud, tender leaf, tender branch and mature fruit were similar to that in mature leaf, but those in flower, stem, root, coarse branch were obviously lower and that in green fruit were significantly higher than that in mature leaf. Conclusions：Mangiferin contents in different parts of mango tree are different.
