OBJECTIVE: To study the chemical constituents in the fruits of Siraitia grosvenorii.
METHOD: Isolation and purification of the constituents were carried out on column chromatography. Their structures were identified by NMR and MS spectral analysis.
RESULT: Six compounds were isolated and elucidated as mogroside IIIA1 (1), siamenoside I (2), mogroside IVa (3), mogroside IVe (4), mogroside V (5) and 11-oxo-mogroside V(6), respectively.
CONCLUSION: Compound 1, mogrol-24-O-beta-D-glucopyranosyl (1 --> 2)-[beta-D-glucopyranosyl(1 --> 6) ]-beta-D-glucopyranoside, was identified as a new natural product from the fruits of S. grosvenorii.
