| Summary: | 碩士 === 國立屏東教育大學 === 化學生物系 === 99 === In the study, dried rhizome of Rheum officinale has been extracted with methanol for six times. The crude extract was further partitioned with hexane、ethyl acetate、butanol and water. From the EtOAc layer, we obtained seven compounds, including four anthraquinones: Chrysophanol、Emodin、Physcion、Aloe-emodin; two Benzenoids: Raspberry acid、trans-Resveratrol; and an unknown A. It needs more experiments such as HMBC spectroscopy analysis to confirm the unknown A''s structure.
