Abstract
Two new sesquiterpenes, named selina-4(14),7,11-trien-9-ol (1) and selina-4(14),11-dien-7-ol (2), along with two known compounds were isolated from rhizomes of Atractylodes macrocephala Koidz. All structures were assigned on the basis of detailed spectroscopic analyses. The absolute configuration of 1 was established by TDDFT-ECD calculations. Compound 1 was found to moderately inhibit LSD1 activity with IC50 value of 34.0 μM. Compounds 1 and 4 exhibited a regulate effect on Keap1-Nrf2-ARE pathway.
