Oxytrodiflavanone A and Oxytrochalcoflavanones A,B: New Biflavonoids from Oxytropis chiliophylla
Yang Liu, Norbo Kelsang, Jianghai Lu, Yingtao Zhang, Hong Liang, Pengfei Tu, Dexin Kong,* and Qingying Zhang*
Three previously undescribed biflavonoids, oxytrodiflavanone A (1), and oxytrochalcoflavanones A,B (2,3), were isolated from the aerial part of Oxytropis chiliophylla, together with their putative biosynthetic monomers, i.e., (2S)-5,7-dihydroxyflavanone (4), (2S)-7-hydroxyflavanone (5), and 2′,4′-dihydroxychalcone (6). The structures of these compounds were elucidated by a combination analysis of spectroscopic data. The cytotoxic activities of all the isolated compounds against PC-3 human prostate cancer cell line are also presented.

Structurally Diverse Cytotoxic Dimeric Chalcones from Oxytropis chiliophylla
Yang Li, Xiaojing Zhang, Norbo Kelsang, Guangzhong Tu, Dexin Kong, Jianghai Lu, Yingtao Zhan, Hong Lian, Orcid, Pengfei Tu, Orcid, and Qingying Zhang, Orcid
Ten isomeric cyclobutane- and cyclohexene-containing chalcone dimers, oxyfadichalcones A–G, were isolated from the aerial parts of Oxytropis chiliophylla. These included six new compounds and three pairs of enantiomers that are being reported from natural sources for the first time. The relative configurations were elucidated by spectroscopic data analysis, while the absolute configurations were determined by comparing the experimental and calculated electronic circular dichroism spectra. Quantitative LC-MS analysis of the main dimers from different parts of the plant revealed their characteristic accumulation in the viscous secretion and provided supporting evidence for the hypothesized photochemical biosynthesis. In addition, the cytotoxic activities of all isolates against the PC-3 human prostate cancer cell line are reported.

Repeated chromatography of the n-BuOH soluble fraction from ethanol extract of the aerial part of Oxytropis chiliophylla led to the isolation of six new rhamnocitrin glycosides, named oxychilioflavonosides A−F (1–6), together with eight known rhamnocitrin glycosides (7–14) of which six were isolated from the genus Oxytropis for the first time. The structures of these compounds were elucidated by extensive spectroscopic techniques and chemical methods. All isolated compounds were evaluated for their anti-inflammatory activity in lipopolysaccharide (LPS)-induced BV-2 microglial cells, and compound 11 showed potent inhibition on NO production with IC50 value of 9.91 μM. sciencedirect.com
