Yang, Jing published the artcileQuantitative analysis of flavonoids in different medicinal parts of Morus alba, Formula: C14H10O4, the publication is Zhongguo Yaofang (2014), 25(27), 2550-2552, database is CAplus.
The aim is to determine contents of total flavonoids in leaves, fruit, branch and root bark of Morus alba. With moracin as substance control, the contents of total flavonoids in 95% ethanol extract, water extract after ethanol extraction from the leaves, fruit, branch and root bark of M.alba were measured by spectrophotometry. The linear range of moracin was 0.025-0.050mg/mL(r=0.9998). RSD of precision, stability and reproducibility tests were all lower than 1%. The mass fraction of total flavonoids in 95% ethanol extract from the leaves, fruit, branch and root bark of M. alba was 13.60%, 7.19%, 10.53% and 18.38%. The mass fraction of total flavonoids in water extract after ethanol extraction from the leaves, fruit, branch and root bark of M. alba was 0.26%, 0.60%, 0.40% and 0.01%. The content of total flavonoids in root bark of M. alba is the highest, ethanol extract of it is effective.
