Lanostane-type triterpenes from the sclerotium of Inonotus obliquus (Chaga mushrooms) as proproliferative agents on human follicle dermal papilla cells.J Nat Med. 2019 Jun; 73(3):597-601.JN
Chaga mushrooms, the sclerotium of Inonotus obliquus, have been used in Mongolia as a traditional hair shampoo to maintain healthy hair. Bioassay-guided fractionations of the extract of Chaga mushrooms using a proliferation assay on human follicle dermal papilla cells (HFDPCs) gave five lanostane-type triterpenes (1-5), whose structures were identified by spectroscopic evidence. Among these, lanosterol (1), inotodiol (3), lanost-8,24-diene-3β,21-diol (4), and trametenolic acid (5) demonstrated proproliferative effects on HFDPCs more potent than minoxidil, an anti-alopecia agent, used as the positive control. The lanostane-type triterpenes (1, 3, 4, and 5) appeared to be potential candidates of new agents possibly used for hair-care with a stimulative effect on hair growth.
