It is anti-inflammatory, antioxidant, anticarcinogenic, antimutagenic, anticoagulant, antidiabetic, antibacterial, antifungal, antiprotozoal, antiviral, antifibrotic, antivenom, anti-ulcer and hypocholesteremic. Its anticancer effect is mainly mediated through induction of apoptosis. Its anti-inflammatory, anticancer and antioxidant roles may be clinically exploited to control rheumatism, carcinogenesis and oxidative stress-related pathogenesis. Clinically, curcumin has already been used to reduce post-operative inflammation, Thus, curcumin has the potential of chemopreventive action and has been used in the development of modern medicine to treat various diseases.展开更多

This technology can effectively separate the starch and cellulose from Dioscorea Zingiberensis, thus the output of diosgenin is raised by 20%. Meanwhile using the suspension after separation, the synergy of enzymes, which are under the best condition for enzymolysis is studied, and an enzymolysis model, which uses two enzymes at the same time, is established. This model provides a theoretical basis for finding new enzyme resources. What＇s more orthogonal experiments show that by using this model, either the output of diosgenin can be increased by 50.58% or the amount of acid used can be reduced by 83% which means less pollution.展开更多
