Oleanane triterpenoids with PTP1B and -glucosidase inhibitory activities from .

Eleven oleanane triterpenoids (-) including two new ones ( and ) were isolated from the roots and stems of . Their structures were established by extensive spectroscopic analysis, comparison with literature, and NMR calculations. Compounds and represent the first examples of 23-hydroxy-28--oleanane and 21-hydroxy-olean-3-one triterpenoids, respectively.

Anti-Inflammatory Triterpenoids from the Maximin LPS-Stimulated RAW264.7 Cells.

Maxim is widely distributed in China and used as a traditional herbal medicine to induce childbirth, ease the pain of labor, rectify delayed or irregular menstruation, alleviate heavy bleeding and pain during menstruation, and treat external injuries and irregular menses. According to our detailed chemical investigation, three new triterpene derivatives (⁻), together with seven known compounds, were isolated from the root and rhizome of Maxim. Their structures were elucidated by 1D- and 2D-NMR spectroscopic analysis and physio-chemical methods.

Two New Phenanthrene Glucosides from Cremastra appendiculata and their Cytotoxic Activities.

Two new phenanthrene glucosides, named 2'-hydroxy-4,4',7'-trimethoxy-1, l'-biphenanthrene-2,7-di-O-β-D-glucoside (1) and 1-(4-hydroxybenzyl)-4-methoxy-2,7-dihydroxy-phenanthrene-8-O-β-D-glucoside (2), together with three known compounds were isolated from the tubers of Cremastra appendiculata (D.Don) Makino. Their structures were elucidated on the basis of spectral data.
