不同倍性何首乌中二苯乙烯苷和蒽醌类的含量比较

目的:考察二倍体与三倍体何首乌中二苯乙烯苷、蒽醌类成分的含量差异。方法:采用Inertsil ODS-3C18柱,分别用乙腈-水(25∶75)、甲醇-0.1%磷酸(85∶15)作为流动相,在320 nm和254 nm处检测2,3,5,4′-四羟基二苯乙烯-2-O-β-D-葡萄糖苷、蒽醌类成分的含量。结果:广东德庆二倍体何首乌中二苯乙烯苷的含量最高,广西靖西三倍体何首乌中结合型蒽醌的比例达到了85%。结论:不同倍性何首乌中化学成分存在差异。

Comparison of Content of 2,3,5,4''''-Tetrahydroxystilbene-2-O-β-D-Glucoside and Anthraquinon in Different Ploidy Radix Polygoni Multiflori

OBJECTIVE: To investigate the content of 2,3,5,4'-tetrahydroxystilbene-2-O-beta-D-glucoside and anthraquinon in diploid and triploid Radix Polygoni Multiflori. METHODS: 4 batches of Radix Polygoni Multiflori were collected from different districts. The content of 2,3,5,4'-tetrahydroxystilbene-2-O-beta-D-glucoside and anthraquinon in these samples were determined at 320 nm and 254nm wave length by HPLC with Inertsil ODS-3 C18 pillar and acetomitrile: aqua (25:75), methanol: 0.1% phosphoric (85:15) respectively as the mobile phase. RESULTS: The maximum content of 2,3,5,4'-tetrahydroxystilbene-2-0-beta-D-glucoside was diploid Radix Polygoni Multiflori from Deqing Guangdong. The maximum ratio of total anthraquinon was triploid Radix Polygoni Multiflori from Jinxi Guangxi reached 85%. CONCLUSION: The content of anthraquinon varies greatly in the samples from the different producing areas.
