A nor-protostane, alisolide (1), a rearranged protostane, alisol O (2), and a 2,3-seco-protostane triterpene, alisol P (3), were isolated from the rhizomes of Alisma orientale, along with eight known protostane triterpenes. The structures were elucidated to be (17S)-3,11-dioxo-23-nor-protost-12-en-23(17)-olide, 3-oxo-11 beta,23-dihydroxy-24,24-dimethyl-26,27-dinorprotost-13(17)-en-25-oic acid, and (20R,23S,24R)-23,24,25-trihydroxy-2,3-seco-protost-13(17)-en-3-oic acid 2,11 beta-lactone, respectively, by interpretation of spectroscopic data.
