(2, 3, 5–10) were isolated from a 70% ethanol extract of Polygonum multiflorum roots. The structures were determined by 1H and 13C NMR, HMQC, and HMBC spectrometry. Extracts of P. multiflorum have been reported to promote hair growth in vivo. This study was carried out to evaluate the effects of isolated compounds from P. multiflorum on promoting hair growth using dermal papilla cells (DPCs), which
两个新的化合物,torachrysone -8-的没食子酸酯ö -β- d葡糖苷(1)和(Ë)-2,3,5,4'-二苯乙烯-2- ö -β- d -xyloside(4) ,与八个已知化合物(沿2,3,5 - 10)从70%的乙醇提取物中分离何首乌根。通过1 H和13 C NMR,HMQC和HMBC光谱确定结构。何首乌提取物已有报道可促进体内毛发生长。进行了这项研究,以评估利用何首乌分离出的化合物利用真皮乳头细胞(DPC)促进毛发生长的作用,而真皮乳头细胞在毛发生长中起着重要作用。当DPC的用化合物(处理过的1 - 10)从何首乌,化合物1,2,3,6,和10增加毛乳头细胞的增殖与对照组相比。具体来说,化合物2(10和20μM)引起的DPC增殖比米诺地尔(10μM)更大。另外,用化合物2处理触须毛囊21天显着增加了毛发长度。基于该结果,对这些衍生物的进一步研究和优化可能有助于开发用于治疗脱发的治疗剂。
