TL;DR: One triterpene saponin was isolated from Panax japonicus C. A. Meyer var major (Burk.) C. Y. Wu et al. as discussed by the authors, which showed moderate antitumor activities against the A2780 cells and OVCAR-3 cells.

TL;DR: A new xanthene, named blumeaxanthene was isolated from Blumea riparia DC as mentioned in this paper, and the structure was elucidated on the basis of the data of NMR, MS, IR.

TL;DR: Two cucurbitane-type triterpenoids, (23 E )-5 β,19-epoxycucurbita-6,23,25-triene-3 β -ol, together with three known compounds, have been isolated from the fruit of Momordica charantia L. Their structures were determined on the basis of spectral analysis as mentioned in this paper.

TL;DR: One new dammarane-type triterpene saponin, named (20 S )-3β,20,21-trihydroxydammar-24-ene 3- O -[α- l - rhamnopyranosyl(1−→ 2)][β- d -xylopyranoyl( 1−→ 3)]-β-d -glucopyraniumide ( 1 ), was isolated from the aerial parts of Gynostemma pentaphyllum (Thunb.) Makino as discussed by the authors

TL;DR: Cunninghamella elegans has been employed for the biotransformation of cinobufagin to afford one metabolites and the structure of the transformation product has been characterized as 7β,12β-dihydroxylcinabufagin, a new compound.
