Abstract: The invention provides compounds of structural formula I or a salt thereof, and total saponins comprising such compounds in the preparation of anti-tumor agents. The present study of this invention showed that the compounds of formula I and the related total saponins had strong inhibitory effects on the proliferation of several human tumor cell lines, such as hepatocarcinoma, gastric cancer, colon cancer, breast cancer and melanoma cell lines, also the combination of structural formula I and the chemical agents could fairly well reduce toxicity and increase treatment effects.

Abstract: The method for treating diabetes in an individual includes the step of administering a therapeutically effective amount of a pharmaceutically acceptable pentacyclic triterpenoid saponin compound to the individual suitable to provide therapeutic levels of insulin to the individual. The compound can be administered by injection, transdermal contact, or nasal spray. The method includes mixing the compound with an additive into an ingestible so that the therapeutic effective amount passes through the gastric acid of the stomach to the bloodstream.

Abstract: The application of pentacyclic triterpenoid saponins, extracted from the plant of Silene viscidula, is used to manufacture anti-diabetic medicaments. Having screened and researched the plants and the compounds massively, the compounds of pentacyclic triterpenoid saponins extracted and purified from Silene viscidula (hereinafter called Wacao saponnins), have strong effects on hyperglycemia, especially for the compounds that have mother nuclei of sinocrassulosides, which can be used to manufacture anti-diabetic medicaments.
