Biological Activities
Compounds
Conditions
Epigynum griffithianum contains a specific triterpenoid saponin isolated from its stems that functions as an immunosuppressive agent. This newly identified compound, labeled as compound 1, was tested for its biological impact on the proliferation of mice splenocytes. During in vitro evaluation, the substance demonstrated significant ability to treat or suppress this cellular proliferation. Its effectiveness was notably high when compared to the positive control, dexamethasone, at a concentration of 25 μM. Consequently, the plant's chemical constituents play a direct role in modulating mouse splenocyte activity.
Preparations
Parts used
Epigynum griffithianum serves as a significant source of bioactive chemical compounds found within its structural components. Specifically, the plant's stems contain unique triterpenoid saponins that have attracted scientific interest. During chemical investigations of these stems, researchers successfully isolated a new triterpenoid saponin alongside two previously known compounds. Detailed spectroscopic analysis was employed to elucidate these structures and confirm their identities. Ultimately, the new compound demonstrated significant immunosuppressive activities when evaluated in vitro against mice splenocyte proliferation.
