Among them, 10-hydroxycamptothe-cine has a wide anticancer spectrum and is lesstoxic. In suspension, it exhibits some therapeu-tic effects on primary hepatic cancer, gastriccarcinoma, cancer of the urinary bladder andleukemia.展开更多

The effective elements con- tained in GBE are mainly kinds of Ginkgo flavonoid and Ginkgolide, which have marked protective effects on cardio-cerebral vascular and central nerve systems. In clinical practice, it is applied mostly in treatment of cardio-cerebral vascular diseases. Also it shows apparent effects in the treatment processes of some other diseases as an adjuvant, and therefore, has been gradually accepted by the medical circle in the world, proving to be a medicine of wide prospect in development and application.展开更多
