云南马铃薯地方彩色品种“剑川红”和“转心乌”的花色苷主成分分析

彩色马铃薯富含花色苷,是一种天然抗氧化食品.本研究采用高效液相色谱质谱联用技术以引进品种“黑美人”为对照分析了云南马铃薯地方特色品种“剑川红”和“转心乌”花色苷的主要成分.结果表明:“剑川红”色素主要为酰化天竺葵色素类花色苷,其主要成分为天竺葵素3-[ 6-O-( 4-O-E-p-香豆酰-O-α-吡喃鼠李糖苷)-β-D-吡喃葡萄糖苷]-5-O-β-D-毗喃葡萄糖苷.“转心乌”和“黑美人”所含色素相似,主要为酰化矮牵牛色索、锦葵色素、芍药色素类衍生物,主要成分均为矮牵牛花色素3-[ 6-O-( 4-O-E-p-香豆酰-O-α-吡喃鼠李糖苷)-β-D-毗喃葡萄糖苷]-5-O-β-D-毗喃葡萄糖苷.

Main Anthocyanins Analysis of Native Pigmented Potatoes ' Jianchuanhong' and ' Zhuanxinwu' of Yunnan Province

Pigmented potato(Solanum tuberosum L.) is a natural antioxidative food containing plentiful anthocyanins.In this paper,the pigment compositions of the red-fleshed potato cultivars ’Jianchuanhong’,the blue-fleshed ’ZHXW’,and ’Heimeiren’ were analyzed by HPLC-MS.The results indicated that ’Jianchuanhong’ contained acylated pelargonidin derivatives and the main pigment was pelargonidin-3-[6-O-(4-O-E-p-coumaroyl-O-α-rhamnopyranosyl)-β-D-glucopyran-oside]-5-O-β-D-glucopyranoside.The anthocyanin constituents of ’ZHXW’ and ’Heimeiren’ were similar which contained several acylated derivatives of petunidin,malvidin and peonidin,and the main pigment was petunidin-3-[6-O-(4-O-E-p-coumaroyl-O-α-rhamnopyranosyl)-β-D-glucopyranoside]-5-O-β-D-glucopyranoside.
