Seborrheic alopecia is the most frequently observed among its various types, contributing to over 25% of hair loss cases in men. Identifying effective natural compounds or therapeutic agents that stimulate hair growth remains a key research focus. Platycladus orientalis L., known for its medicinal properties, shows potential in promoting hair darkening and regeneration, although its mechanisms remain unclear. In this study, Fr2 of Platycladus orientalis L. was found to significantly enhance hair growth in mice. Similarly, (7E)-7,8-Dehydroheliobuphthalmin (DHHB) was successfully isolated and purified for the first time through a combination of medium-pressure liquid chromatography and two-dimensional high-performance liquid chromatography. In an alopecia areata (AGA) model using dermal papilla cells (DPCs), DHHB was found to significantly promote cell proliferation and differentiation by down-regulating the expression of androgen receptor (AR) proteins, and activating the Wnt\/\u03b2-catenin signaling pathway, as compared with the dihydrotestosterone-induced model group. These results indicate that DHHB is a major bioactive compound in Platycladus orientalis L. and represents a promising candidate for promoting hair growth.<\/jats:p>","DOI":"10.3390\/ijms26115189","type":"journal-article","created":{"date-parts":[[2025,5,28]],"date-time":"2025-05-28T10:21:13Z","timestamp":1748427673000},"page":"5189","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["(7E)-7,8-Dehydroheliobuphthalmin from Platycladus orientalis L.: Isolation, Characterization, and Hair Growth Promotion"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-9313-3166","authenticated-orcid":false,"given":"Zikai","family":"Lin","sequence":"first","affiliation":[{"name":"Center for Mitochondria and Healthy Aging, College of Life Sciences, Yantai University, Yantai 264003, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-9851-1911","authenticated-orcid":false,"given":"Yan","family":"Sun","sequence":"additional","affiliation":[{"name":"College of Traditional Chinese Medicine, Shandong University of Traditional Chinese Medicine, Jinan 250355, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chengzhao","family":"Li","sequence":"additional","affiliation":[{"name":"Center for Mitochondria and Healthy Aging, College of Life Sciences, Yantai University, Yantai 264003, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaowei","family":"Zhou","sequence":"additional","affiliation":[{"name":"Xinjiang Production and Construction Corps Key Laboratory of Protection and Utilization of Biological Resources in Tarim Basin, College of Life Science, Tarim University, Alar 843300, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuting","family":"Guo","sequence":"additional","affiliation":[{"name":"College of Traditional Chinese Medicine, Shandong University of Traditional Chinese Medicine, Jinan 250355, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhenhua","family":"Wang","sequence":"additional","affiliation":[{"name":"Xinjiang Production and Construction Corps Key Laboratory of Protection and Utilization of Biological Resources in Tarim Basin, College of Life Science, Tarim University, Alar 843300, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5743-0963","authenticated-orcid":false,"given":"Gang","family":"Li","sequence":"additional","affiliation":[{"name":"Center for Mitochondria and Healthy Aging, College of Life Sciences, Yantai University, Yantai 264003, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"131","DOI":"10.4103\/0974-7753.58556","article-title":"Male androgenetic alopecia: Population-based study in 1005 subjects","volume":"1","author":"Chakravarthi","year":"2009","journal-title":"Int.
