【摘要】：選取新疆特色植物藥桑與黑桑的桑葚、桑葉和桑樹皮為研究對(duì)象,分別利用高效液相色譜法、原子吸收光譜法、紫外分光光度法和常規(guī)方法測(cè)定氨基酸、礦物質(zhì)、黃酮、多糖和生物堿含量。結(jié)果表明:藥桑和黑桑不同部位中蛋白氨基酸種類豐富,均含有17種氨基酸,必需氨基酸與總氨基酸的比值均在0.60以上;對(duì)人體有益的礦物質(zhì)含量也較豐富;生物活性物質(zhì)含量也較為豐富,其中藥桑葚中生物堿含量最高,可達(dá)1.393 mg/g(干基),藥桑皮中黃酮含量最高,可達(dá)11.999 mg/g(干基),黑桑葚中多糖含量最高,可達(dá)337.491 mg/g(干基)。利用主成分分析對(duì)29個(gè)指標(biāo)提取了4個(gè)主成分,累計(jì)方差貢獻(xiàn)率達(dá)97.000%。綜合評(píng)分結(jié)果表明藥桑價(jià)值更高。
[Abstract]:The mulberry, mulberry leaf and mulberry bark of Xinjiang characteristic plant mulberry, mulberry leaf and mulberry bark were selected for the determination of amino acids, minerals and flavonoids by high performance liquid chromatography (HPLC), atomic absorption spectrometry (AAS), ultraviolet spectrophotometry (UV) and routine methods, respectively. Polysaccharides and alkaloids. The results showed that there were 17 kinds of amino acids in different parts of Mulberry and black mulberry, the ratio of essential amino acids to total amino acids was above 0.60, and the mineral content of beneficial to human body was also rich. The content of bioactive substances in mulberry was the highest, up to 1.393 mg/g (dry base), flavonoids in mulberry peel was highest, 11.999 mg/g (dry base), polysaccharide content in black mulberry was the highest. It can reach 337.491 mg/g (dry base). Four principal components were extracted from 29 indexes by principal component analysis, and the cumulative contribution rate of variance was 97.000. The comprehensive score showed that the value of medicinal mulberry was higher.
