Phytochemicals from were studied for hair rejuvenation activity using BalB/c mice. Solvent extractions and thin layer chromatography (TLC) were used to extract and isolate the phytochemicals respectively. Phytochemicals were identified by spraying with target-specific revealing reagents. hair growth stimulating activity for each extract was tested on denuded dorsal skin of 5-week old BalB/c mice against the controls and the standard drug minoxidil. The parameters used to evaluate hair growth were hair growth completion time, hair length, hair weight, hair follicle length, and relative hair follicle area. The identified phytochemicals from the active ethanol extract were steroidal glycosides, triterpenoid glycosides, and flavonoid glycosides. Flavonoid glycosides treatment had the uppermost hair rejuvenation capacity as measured by the shortest hair growth completion time (19 days) versus control (29 days) and longest hair length (11.04 mm and 11.86 mm for male and female mice respectively while the control group had 5.15 mm for male mice and 5.33 mm for female mice). Hair growth stimulation by flavonoid glycosides was also dependent on dose concentration. It can be concluded from this study that flavonoid glycosides extracted from the leaves of have remarkable hair rejuvenation capacity in BalB/c mice. The present results provides insights on the use of for hair rejuvenation in traditional practices and on the potential of the plant as a source of novel compounds that can be used as hair growth promoters.
使用BalB/c小鼠研究了[植物名称未给出]中的植物化学物质的毛发再生活性。分别采用溶剂萃取和薄层色谱(TLC)法提取和分离植物化学物质。通过用目标特异性显色试剂喷雾来鉴定植物化学物质。在5周龄BalB/c小鼠的背部脱毛皮肤上测试每种提取物对对照和标准药物米诺地尔的毛发生长刺激活性。用于评估毛发生长的参数有毛发生长完成时间、毛发长度、毛发重量、毛囊长度和相对毛囊面积。从活性乙醇提取物中鉴定出的植物化学物质为甾体糖苷、三萜糖苷和黄酮糖苷。通过最短的毛发生长完成时间(19天,对照为29天)以及最长的毛发长度(雄性和雌性小鼠分别为11.04毫米和11.86毫米,而对照组雄性小鼠为5.15毫米,雌性小鼠为5.33毫米)来衡量,黄酮糖苷处理具有最强的毛发再生能力。黄酮糖苷对毛发生长的刺激也取决于剂量浓度。从这项研究可以得出结论,从[植物名称未给出]叶子中提取的黄酮糖苷在BalB/c小鼠中具有显著的毛发再生能力。目前的结果为传统实践中使用[植物名称未给出]进行毛发再生以及该植物作为可用于促进毛发生长的新型化合物来源的潜力提供了见解。
