EFFECT OF SUNLIGHT, HEAT AND pH ON BIOLOGICAL POTENCY OF ACTIVE COMPONENTS OF CHINESE BITTERSWEET (CELASTRUS ANGULATUS MAX.)

Wu Wenjun Zhang Xinrui (Department of Plant Protection)  
Although temperature and pH may have some effects on biological potency of the active components of Chinese bittersweet, those effects are small. Under the condition of 80CC and pHlO, the active components withstanding for 4 hours might give 15% reduction in activity. Exposure of theactive componets of Chinese bittersweet to sunlight caused a slow decrease in biological potency. The active comronents exposed in the sunlight for 9 days gave only 24% reduction in activity as compared to the unexposed active components.
