Abstract:

Objective: To explore the chemical constituents from the underground part of Isodon lophanthoides. Methods: The
compounds were isolated and purified by silica gel and Sephadex LH-20 column chromatography. Their structures were identified by
various spectral analysis and physicochemical properties. Results: Five steroidal compounds and two ceramide compounds were
obtained from ethyl acetate fraction of 70% acetone-water extract of the Isodon lophanthoides underground part and identified as
stigmast-4-ene-3-one(1), stigmasterol(2), 7α-hydroxysitosterol(3), daucosterol(4), 5α, 6β-dihydroxy-daucosterol(5),(2S, 3S,
4R, 8E)-2-[(2′R)-2-hydroxytetracosanoylamino]-1, 3, 4-octadecanetriol-8-ene(6), and 1-O-β-D-glucopyranosyl-(2S, 3R, 4E,
8Z)-2-[(2′R)-2-hydroxytetracosanoylamino]-1,3-octadecanediol-4, 8-diene(7). Conclusion: All of these compounds except for
2 and 4 were isolated from this plant for the first time, while the compounds 5-7 were firstly obtained from the underground part of
Isodon plants.
