A new ursane-type triterpenoid saponin from the aerial parts of Clematoclethra scandens subsp. actinidioides.

A new ursane-type triterpenoid saponin, 2α,3α,24-trihydroxyurs-12,20(30)-dien-28-oic acid β-D-glucopyranosyl ester (1), together with six known triterpenoid saponins, was isolated and characterized from the aerial parts of Clematoclethra scandens subsp. actinidioides.

A new triterpenoid glycoside from Vitex negundo.

To investigate the chemical constituents of Vitex negundo. Compounds were isolated by different chromatographic methods and their structures were elucidated on the basis of NMR spectroscopy. Four compounds were isolated and identified as 2α, 3α, 24-trihydroxyurs-12, 20(30)-dien-28-oic acid-28-O-β-D-glucopyranosyl ester (1), corosolic acid (2), vulgarsaponin A (3) and 2α, 3α, 24-trihydroxyurs-12-en-28-oic acid-28-O-β-Dglucopyranosyl ester (4), respectively. Compound 1 is a new triterpenoid glycoside.

Characterization of the complete chloroplast genome of Clematoclethra scandens subsp. actinidioides (Actinidiaceae).

Clematoclethra scandens subsp. actinidioides (Actinidiaceae) is an endemic medicinal species in China. Here, we first sequenced and characterized the complete chloroplast genome of C. scandens subsp. actinidioides. The chloroplast genome was 159,341 bp in length, containing a large single-copy of 88,351 bp and a small single-copy of 21,580 bp separated by a pair of identical inverted repeat regions of 24,705 bp each. A total of 131 genes were identified, including 84 protein-coding genes, 39 tRNA, and eight rRNA genes. The phylogenetic analysis of C. scandens subsp. actinidioides showed a relatively close relationship with Clematoclethra scandens subsp. hemsleyi.
