One new triterpenoid, 3β-[(E)-caffeoyloxy]-D:C-friedooleana-7,9(11)-dien-29-oic acid (1) and nine known triterpenoidsidentified as cucurbitacin B (2), 23,24-dihydrocucurbitacin B (3), 23,24-dihydrocu-curbitacin D (4), cucurbitacin D (5), cucurbalsaminol A (6), 3-epi-isocucurbitacin D (7), curbitacin G (8), cucurbitacin J (9) and cucurbitacin I (10)were purified from Trichosanthes cucumeroides. Their structures were confirmed by spectroscopic data analysis and comparison with previous literature. All compounds were obtained from T.cucumeroides for the first time.
