Major classes and types of phenolic compounds isolated from the root bark are flavonoids(kuwanons, morusin, cyclomorusin and sanggenons), benzofurans(moracins and mulberrofurans), and stilbenoids(mulberrosides). Some of the flavonoids and benzofurans are products of Diel-Alder type adducts. Other classes of compounds include triterpenes, phenolic acids and coumarins. Morusin, a prenylated flavonoid, was first isolated from the root bark of M. alba, and later from the leaf, stem bark and twig of the plant. The potent anti-cancer properties of morusin have attracted much attention with research on-going and new findings being published. The compound inhibits angiogenesis, tumour progression and tumour migration, and triggers apoptosis, cell cycle arrest and autophagy in colorectal, cervical, prostate, breast, hepatoma, pancreatic, glioblastoma, gastric, ovarian and lung cancer cell lines. The anti-cancer activities of morusin are executed via various molecular targets and signalling pathways. It is anticipated that on-going in vitro studies will progress gradually to in vivo studies using animal models before efforts towards drug development can be initiated for clinical trials.展开更多

The experimental results showed that morusin is present in all parts of the mulberry bush. The content of morusin was highest in root bark and second highest in branch bark. The difference in morusin content of 20 different species of cultivated mulberry branch bark was significant. The level of morusin was highest in the branch bark of cultivated mulberry No. 404, a tetraploid cultivar, and third in the Husang 32 cultivar of Morus multicaulis. The method used in this study for determining morusin content exhibited good repeatability (RSD 6.02%) and recovery (100.62%). Therefore, the results from this study provide reliable data, for research and development in the future, on the level and distribution of morusin in mulberry in general and the differences found between various cultivated mulberries in particular. Furthermore, the HPLC-DAD method to determine morusin content is fast and reliable and is applicable not only to mulberry bushes but also to other plants.展开更多
