摘要 为比较常见深色表皮农产品中花青素的种类和含量,采用高效液相色谱法对市场内常见的20种深色表皮农产品中6种花青素(飞燕草素、矢车菊素、矮牵牛素、天竺葵素、芍药色素和锦葵色素)进行测定分析。结果表明,20种深色表皮农产品中花青素种类和含量差异较大,花青素种类为1~5种不等,含量在2.6~1 144.2 mg/kg,其中黑果枸杞花青素含量最高,蓝莓、巨峰葡萄果皮和黑加仑葡萄干中检出花青素品种较多。

Abstract In order to compare the kinds and contents of anthocyanins in common dark skinned agricultural products, six kinds of anthocyanins (delphinidin, cyanidin, petunia, pelargonidin, paeoniflorin and malliflorin) in 20 kinds of dark skinned agricultural products were determined by high performance liquid chromatography. The results showed that there were significant differences in anthocyanin types and contents among 20 kinds of dark skinned agricultural products. The anthocyanin types was 1-5, and the content was 2.6-1 144.2 mg/kg. Among them, Lycium ruthenicum Murr. had the highest anthocyanin content, and anthocyanins were the more diverse in blueberry, the peel of Kyoho grape and raisin of blackcurrant.

花青素和甜菜色素、胡蘿卜素、叶绿素并称为四大类植物色素,是一类含有多种酚羟基的黄酮类化合物,广泛分布于植物的根、茎、叶、花及果实组织中,是植物呈现紫色、红色等鲜艳颜色的重要原因之一[1]。已知自然界中花青素有20多种,其中飞燕草素、矢车菊素、矮牵牛素、天竺葵素、芍药色素和锦葵色素是高等植物中常见的6种花青素[2]。花青素因其独特的结构特性,具有抗氧化、抗炎抗菌、抗肿瘤、预防心脑血管疾病、降血糖等功效,同时由于来源广泛、细胞毒性小和食用安全等特点受到国内外学者的广泛关注[3-4]。
花青素在自然状态下较少以游离状态存在,通常与糖结合形成花色苷,而花色苷中的羟基和糖苷基与羧酸及衍生物进行酰基化反应转变成较为稳定的花色苷[5]。因为花色苷的种类多、含量少,难以提纯保存,故通常通过碎片离子进行物质的推测[6]。……
