Two new isoflavone glycosides from Mucuna birdwoodiana. Gong Ting,Zhang Ting,Wang Dong-Xiao,Liu Ping,Chen Ruo-Yun,Yu De-Quan Journal of Asian natural products research Two new isoflavone glycosides, mucodianins E (1) and F (2), have been isolated from the vine stems of Mucuna birdwoodiana Tutch. Their structures have been established as retusin 7-O-beta-D-xylopyranosyl-(1 --> 6)-beta-D-glucopyranoside (1) and 8-O-methylretusin 7-O-beta-D-xylopyranosyl-(1 --> 6)-beta-D-glucopyranoside (2) by means of spectroscopic analysis and chemical methods. 10.1080/10286020903517540

[Chemical constituents of stem barks of Mucuna birdwoodiana]. Gong Ting,Wang Dongxiao,Liu Ping,Chen Ruoyun Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica Eleven compounds were isolated from the stem bark of Mucuna birdwoodiana. Their structures were elucidated by various spectral analyses and identified as 3'-methoxycoumestrol(1), formononetin(2), genisten(3), 8-0-methylretusin(4), 7, 3'dihydroxy-5'-methoxyisoflavone(5), chrysophanol(6), syringaresinol(7), epifriedelanol(8), lupeol(9), respectively. All compounds except 2,3,8 and 9 were isolated from the genus for the first time. 10.4268/cjcmm20101315

A novel 3-arylcoumarin and three new 2-arylbenzofurans from Mucuna birdwoodiana. Gong Ting,Wang Dong-Xiao,Yang Yan,Liu Ping,Chen Ruo-Yun,Yu De-Quan Chemical & pharmaceutical bulletin A novel coumarin (1, mucodianin A), three new 2-arylbenzofurans (2-4, mucodianins B-D) along with four known ones were isolated from the vine stems of Mucuna birdwoodiana. Their structures were elucidated on basis of spectral analysis. This is the first report of 7-quinonylcoumarin (1) as stable form in natural products. 10.1248/cpb.58.254

Assessing the antioxidant, cytotoxic, apoptotic and wound healing properties of silver nanoparticles green-synthesized by plant extracts. Ahn Eun-Young,Jin Hang,Park Youmie Materials science & engineering. C, Materials for biological applications We synthesized silver nanoparticles using thirty Chinese plant extracts via a green synthetic strategy. UV-visible spectra showed that the silver nanoparticles have an absorbance at 450 nm. Among the thirty extracts, seven extracts (Cratoxylum formosum, Phoebe lanceolata, Scurrula parasitica, Ceratostigma minus, Mucuna birdwoodiana, Myrsine africana and Lindera strychnifolia) exhibited the successful synthesis of silver nanoparticles. These seven extracts showed higher 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and reducing power than the other extracts. The silver nanoparticles synthesized using these seven extracts were mostly spherical with high colloidal stability. The cytotoxicity of these seven silver nanoparticle samples on human lung cancer cells (A549) was clearly higher than that of the extracts alone. Furthermore, the cytotoxicity was affected by the presence or absence of fetal bovine serum. Moreover, the cytotoxicity of the silver nanoparticles synthesized with Cratoxylum formosum and Mucuna birdwoodiana extracts resulted in apoptotic cell death in A549 cells. The wound healing activity observed by the cell scratch method on mouse fibroblast cells (NIH3T3) suggested that the Lindera strychnifolia extract produced silver nanoparticles with decent activity. These results provide ample and systematic information for researchers on the green synthesis of silver nanoparticles using plant extracts. 10.1016/j.msec.2019.03.095
