Nardonaphthalenones A and B (1–2), one new apo-α-carotenone (3) and four new monoterpenoids (4, 8–9 and 11), along with six known compounds (5–7, 10, 12–13) were isolated from the dried roots and rhizomes of Nardostachys chinensis Batal. Their structures were elucidated by analysis of the spectroscopic data including NMR, HRESIMS and circular dichroism data. Furthermore, the serotonin transporter (SERT)-regulating activities of these isolates were evaluated, among them compound 3 showed the strongest enhancement activity while compound 12 showed a moderate inhibition activity on SERT.
