OBJECTIVE
The objectives of this study were to evaluate the in vivo antitumor potential of the triterpenoid fraction from the rhizomes of Astilbe chinensis (Saxifragaceae) (Saxifragaceae) (ATF) and to elucidate its immunological mechanisms by determining its effects on the growth of mouse
The experimental results indicate that the herb Heiji is able to suppress the growth of transplantable tumor (S180) in mice by 30%-51% (P < 0.01), prolong the vital stage of the EAC transplanted mice by 44% (P < 0.01) and raise the lymphocyte transformation rate in lower concentrations in vivo. It
Bioassay-guided fractionation of the rhizomes of Astilbe chinensis afforded four cytotoxic pentacyclic triterpenoids, 3beta-hydroxy-olean-12-en-27-oic acid (1), 3beta,6beta-dihydroxy-olean-12-en-27-oic acid (2), 3beta-acetoxy-olean-12-en-27-oic acid (3), and 3beta-hydroxy-urs-12-en-27-oic acid (4).
3beta-Hydroxy-12-oleanen-27-oic acid (ATA) was an antitumor active oleanane-type triterpenoid from the rhizomes of Astilbe chinensis. ATA was structurally very similar to oleanolic acid, with the only difference being interchange of the carboxyl and methyl group at the C-14 and C-17 positions.
3beta,6beta-dihydroxyolean-12-en-27-oic acid (1) is a pentacyclic triterpenoid isolated from the rhizomes of Astilbe chinensis. To evaluate the in vivo antitumor potential and to elucidate its immunological mechanisms, effect of 1 on the growth of mouse-transplantable tumors, and the immune response
Astilbe rivularis L. is an indigenous medicinal plant growing in high altitude of Darjeeling Himalayan region of India and Nepal. The plant rhizome has been used traditionally as medicine by local tribes to treat various ailments including infectious and other diseases. The present 3 β -Hydroxy-12-oleanen-27-oic acid (ATA) was a main antitumor active triterpene from the rhizomes of Astilbe chinensis. In this study, we investigated its effects on growth, apoptosis, cell cycle, motility/invasion, and metatasis in human hepatoma HepG2 cells in vitro and antimetastasis of B16-F10
