TL;DR: Two new acetylenic glucosides, 4',6'-acetonide-8Z-decaene-4,6-diyne-1-O-beta-D-glucopyranoside named carthamoside A and 4, 6-decadiyne

TL;DR: Seven new steroidal glycosides were isolated from the 95% ethanol extract of the roots of Cynanchum amplexicaule and their structures were determined based on spectral and chemical evidence.

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 new acetylenic glucosides, carthamoside A1 (1) and 4,6decadiyne-1-O-β-D-glucopyranoside A2 (2), were identified from the air-dried flower of Carthamus tinctorius as mentioned in this paper.

TL;DR: In this article, a piperazine-2,5-dione, named gliocladride, was isolated from marine fungus Gliocladium sp. The structure was established on the basis of spectral data, and the stereochemical assignments were made by 1 H NMR spectrum and chiral HPLC of the hydrolyzed compound.
