A new triterpenoid saponin from Pulsatilla cernua.
A new triterpenoid saponin was isolated from Pulsatilla cernua, along with eight known triterpenoids and triterpenoid glycosides. The new compound was identified as 3-O-beta-D-glucopyranosyl-(1-->4)-alpha-L-arabinopyranosyl-bayogenin-28-alpha-L-rhamnopyranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranosyl ester (1) on the basis of 1D, 2D-NMR techniques, including COSY, HMBC, and H...
متن کاملA new triterpenoid saponin from Gynostemma pentaphyllum.
A new dammarane-type triterpene saponin was isolated from the aerial parts of Gynostemma pentaphyllum (Thunb.) Makino. Its structural elucidation was accomplished mainly on the basis of the interpretation of spectroscopic data, such as IR, HR-TOF-MS and NMR. Its cytotoxic activity was evaluated against one human cancer cell line HL-60 using MTT assay.
متن کاملPulsatilla saponin D: the antitumor principle from Pulsatilla koreana.
By bioassay-guided separation, an already known saponin, Pulsatilla saponin D was isolated from the root of Pulsatilla koreana Nakai as a antitumor component when evaluated by in vivo antitumor activity as well as in vitro cytotoxic activity test. It showed potent inhibition rate of tumor growth (IR, 82%) at the dose of 6.4 mg/kg on the BDF1 mice bearing LLC cells.
متن کاملSaponins with neuroprotective effects from the roots of Pulsatilla cernua.
Four new oleanene-type triterpenoid saponins together with six known saponins were isolated from the roots of Pulsatilla cernua and their structures were elucidated on the basis of spectroscopic data, including 2D NMR spectra and chemical evidence. Among these one of the aglycones (gypsogenin) is reported for the first time from this genus. Some of these compounds showed significant neuroprotec...
متن کاملA New Triterpenoid Saponin and Two Neolignans from Ligularia veitchiana
Phytochemical investigation of the rhizomes and roots of Ligularia veitchiana afforded a new triterpenoid saponin and two known neolignans named liguveitoside B (1), citrusin A (2) and citrusin B (3), respectively. This is the first demonstration of the occurrence of a 8-O-4’ neolignan and the second report on the isolation of triterpenoid saponin in the genus Ligularia. Their structures were e...
