Oleanane-Type Triterpene Glycosides from Camellia phanii and Their α-Glucosidase Inhibitory Activity.

Three new oleanane-type triterpene saponins, named camphanosides A-C (1-3), along with five known compounds, chikusetsusaponin IVa (4), spinasaponin A 28-O-glucoside (5), (-)-epicatechin (6), (-)-epicatechin 3-O-gallate (7), and (-)-epigallocatechin 3-O-gallate (8) were isolated from the leaves Camellia phanii Hakoda & Ninh. Their structures were established by 1D and 2D-NMR and mass spectral analysis and chemical methods. Moreover, compounds 1-5 were also evaluated for α-glucosidase inhibitory activity.

A new iridoid glucoside from the roots of .

A new iridoid glucoside, moridoside (), and nine known compounds, asperulosidic acid (), 6---acetylscandoside (), geniposidic acid (), 2-hydroxymethylanthraquinone (), 2-hydroxymethyl-3-hydroxyanthraquinone (), damnacanthol (), lucidine-ω-methyl ether (), 2-hydroxy-1-methoxyanthraquinone (), and 3,8-dihydroxy-1,2-dimethoxyanthraquinone () were isolated from the methanol extract of How. roots. Their structural identification was carried out based on the spectroscopic evidence.
