摘要
以‘黑杞一号’和野生黑果枸杞为研究对象,对其总酚、总花色苷、总单宁、单体花色苷和非花色苷单体酚类物质进行测定分析。结果表明:(1)与野生黑果枸杞相比,‘黑杞一号’的总酚、总花色苷、总单宁含量分别高出14 250、390和3 330μg/g。(2)‘黑杞一号’和野生黑果枸杞中均检测出4种单体花色苷,包括双葡萄糖苷1种、咖啡酰化葡萄糖苷2种和香豆酰化葡萄糖苷1种,且‘黑杞一号’的4种单体花色苷均显著高于野生黑果枸杞,其中单体花色苷总量比野生黑果枸杞高116.88%(5 672.8μg/g),二甲花翠素咖啡酰化葡萄糖苷含量为野生黑果枸杞的14.93倍。(3)‘黑杞一号’和野生黑果枸杞中均检测到29种非花色苷单体酚,包括黄烷醇类7种、羟基苯甲酸类4种,黄酮醇类18种,并以原儿茶酸含量最高,但‘黑杞一号’非花色苷单体酚总量较野生黑果枸杞低51.42%(2.71μg/g)。
Taking ’Heiqi No.1’ and wild Lycium ruthenicum Murr. as research subjects, we determined and analyzed their total phenolics, total anthocyanins. total tannins, individual anthocyanins and individual nonanthocyanin phenolic compounds. The results showed that:(1) the total phenolics, total anthocyanins and total tannins of ’Heiqi No.1’were 14 250, 390 and 3 330 μg/g higher than those of wild L. ruthenicum.(2) There were 4 individual anthocyanins in ’Heiqi No.1’ and wild L. ruthenicum, including 1 diglucoside, 2 coffee acylated glucosides, and 1 coumaryl glucoside. The 4 individual anthocyanins of ’Heiqi No.1’ were all significantly higher than those of wild L. ruthenicum. The content of individual anthocyanins in ’Heiqi No.1’ was 116.88%(5 672.8 μg/g) higher than that of wild L. ruthenicum. The content of malvidin-3-O-(6-caffeoyl)-glucoside in ’Heiqi No.1’ was 14.93 times than that in wild L. ruthenicum.(3) There were 29 individual nonanthocyanin phenolic compounds in ’Heiqi No.1’ and wild L. ruthenicum, including 7 flavan-3-ols, 4 hydroxybenzoic acids, and 18 flavonols. And the content of protocatechuic acids was the highest. However, the content of individual nonanthocyanin phenolic compounds in ’Heiqi No.1’ was 51.42%(2.71 μg/g) lower than that of wild L. ruthenicum.
