Flavonoid aglycones possess biological activities, such as antioxidant and antidiabetic activities compared to glycosides. Taxifolin, a flavonoid aglycones, is detected only in trace amounts in nature and is not easily observed. Therefore, in this study, to investigate the hair tonic and hair loss inhibitors effect of taxifolin, high content of taxifolin aglycone extract was prepared by enzymatic hydrolysis. Taxifolin effectively regulates the apoptosis of dermal papilla cells, which is associated with hair loss, based on its strong antioxidant activities. However, inhibition of dihydrotestosterone (DHT), which is a major cause of male pattern hair loss, was significantly reduced with taxifolin treatment compared with minoxidil, as a positive control. It was also confirmed that a representative factor for promoting hair growth, IGF-1, was significantly increased, and that TGF-β1, a representative biomarker for hair loss, was significantly reduced with taxifolin treatment. These results suggest that taxifolin from enzymatic hydrolysis of RM is a potential treatment for hair loss and a hair growth enhancer.
与糖苷相比,黄酮苷元具有生物活性,如抗氧化和抗糖尿病活性。紫杉叶素是一种黄酮苷元,在自然界中仅以痕量被检测到,且不易观察到。因此,在本研究中,为了研究紫杉叶素的生发和脱发抑制作用,通过酶水解制备了高含量的紫杉叶素苷元提取物。基于其强大的抗氧化活性,紫杉叶素有效地调节了与脱发相关的真皮乳头细胞的凋亡。然而,与作为阳性对照的米诺地尔相比,用紫杉叶素处理时,对男性型脱发的主要原因二氢睾酮(DHT)的抑制作用显著降低。还证实,用紫杉叶素处理后,促进头发生长的代表性因子IGF-1显著增加,而脱发的代表性生物标志物TGF-β1显著降低。这些结果表明,从RM酶水解得到的紫杉叶素是一种潜在的脱发治疗方法和头发生长促进剂。
