title: Terpenoids from the roots and rhizomes of Nardostachys chinensis.
abstract: A new diterpene, 10-isopropyl-2,2,6-trimethyl-2,3,4,5-tetrahydronaphtha[1,8-bc]oxocine-5,11-diol (1), and a new monoterpene, 6-hydroxy-7-(hydroxymethyl)-4-methylenehexahydrocyclopenta[c]pyran-1(3H)-one, together with four known sesquiterpenes, delta1(10)-aristolene-9beta-ol, debilon, nardosinone, and kanshone A, were isolated from the roots of Nardostachys chinensis. The structures of the new compounds were established on the basis of their spectroscopic data, and the structure of 1 was confirmed by X-ray crystallographic analysis.
