RESUMO
Flavonoid aglycones possess biological activities, such as antioxidant and antidiabetic activities compared to glycosides. Taxifolin, a flavonoid aglycones, is detected only in trace amounts in nature and is not easily observed. Therefore, in this study, to investigate the hair tonic and hair loss inhibitors effect of taxifolin, high content of taxifolin aglycone extract was prepared by enzymatic hydrolysis. Taxifolin effectively regulates the apoptosis of dermal papilla cells, which is associated with hair loss, based on its strong antioxidant activities. However, inhibition of dihydrotestosterone (DHT), which is a major cause of male pattern hair loss, was significantly reduced with taxifolin treatment compared with minoxidil, as a positive control. It was also confirmed that a representative factor for promoting hair growth, IGF-1, was significantly increased, and that TGF-ß1, a representative biomarker for hair loss, was significantly reduced with taxifolin treatment. These results suggest that taxifolin from enzymatic hydrolysis of RM is a potential treatment for hair loss and a hair growth enhancer.
RESUMO
Sapium sebiferum contains a variety of organic acids, flavonoids and phenolic substances, which were linked with the functions of poisoning Oncomelania. Sapium sebiferum is a good plant material of inhibiting Oncomelania. This paper reviews the variety, resources and active ingredients of Sapium sebiferum, and the researches of Sapium sebiferum inhibiting Oncomelania, and forecasts the development of Sapium sebiferum as an inhibiting Oncomelania forest in order to provide the evidence for its penetrating research and development.
