| Abstract: | To search for pharmacologically active constituents of folk medicine, a new pregnane, 2α,3α,15β‐trihy‐droxy‐20(S)‐tigloyl‐pregnane (compound 1), and nine known compounds, geranylgeraniol (compound 2), β‐daucosterol (compound 3), 6‐hydroxystigmast‐4‐en‐3‐one (compound 4), sitoindoside I (compound 5), sitoindoside II (compound 6), β‐sitosterol (compound 7), kaempferol (compound 8), quercetin (compound 9), and rutin (compound 10), were isolated from the ethanol extract of whole plants of Munronia delavayi Franch using chromatographic methods. The structures of compounds 1–10 were elucidated on the basis of spectral data. (Managing editor: Wei Wang) |
