摘要: 为解决云南地区桑葚中花青素含量及桑葚中单体花青素种类的问题,对39种桑葚的花青素含量进行调查与分析。运用pH示差法对总花青素含量进行检测,采用高效液相色谱法检测单体花青素含量,并用分光光度法检测桑葚可食部分的红色素吸光度。结果表明,39份桑葚样品中检测出总花青素的有32份,单体花青素共检出4种,分别为矢车菊素、天竺葵素、芍药花素、锦葵素。矢车菊素在36份样品中被检出,天竺葵素在33份样品中被检出,芍药花素仅在1份样品中被检出,锦葵素在4份样品中被检出。红色素在39份样品中均检出,桑葚果实颜色越深红色素含量越高。‘YX002’、‘红果2号’、‘嘉陵30号’、‘孟统4号’和‘YX001’的红色素、花青素含量高,单体花青素丰富;其中‘YX002’总花青素含量最高,为59.05 mg/L,同时还检测出矢车菊素和天竺葵素。

Abstract:

To address the issues of anthocyanin content and the types of monomeric anthocyanins in mulberries from the Yunnan region, 39 varieties of mulberries were investigated and analyzed for their anthocyanin content. The total anthocyanin content was determined using the pH differential method, the monomeric anthocyanin content was measured using high-performance liquid chromatography (HPLC), and the absorbance of red pigments in the edible parts of the mulberries was detected using spectrophotometry. The results showed that total anthocyanins were detected in 32 out of the 39 mulberry samples, and four types of monomeric anthocyanins were identified: cyanidin, pelargonidin, peonidin, and malvidin. Cyanidin was detected in 36 samples, pelargonidin in 33 samples, peonidin in 1 sample, and malvidin in 4 samples. Red pigments were detected in all 39 samples, with darker-colored mulberry fruits exhibiting higher red pigment content. The varieties ‘YX002’, ‘Hongguo 2’, ‘Jialing 30’, ‘Mengtong 4’, and ‘YX001’ has exhibit high levels of red pigments and anthocyanins, along with a rich diversity of monomeric anthocyanins. Among these, ‘YX002’ can have the highest total anthocyanin content, reaching 59.05 mg/L, and both cyanidin and pelargonidin also be detected in this variety.
