Disclosed is a cucurbitane-triterpenoid compound for activating estrogen receptor activity, and a pharmaceutical composition, use and preparation method thereof. The cucurbitane-triterpenoid compound is presented as formula (I):
wherein a single bond or a double bond is formed between C5 and C10, and a single bond or a double bond is fromed between C8 and C9; when a single bond is formed between C5 and C10, the R
1
is oxygen; while a single bond is formed between C8 and C9, R
2
is carbonyl group (—C═O), methyl hydroxyl group (—CH(OH)), methyl ketone or methyl dimethoxy group (—CH(OCH
3
)
2
); and wherein while R
1
is oxygen (—O—) and R
2
is carbonyl group (—C═O) or methyl hydroxyl group (—CH(OH)), a single bond is formed between R
1
(—O—) and C19 of R
2
such that R
1
and R
2
are formed tetrahydro-2H-pyran-2-one or hemiacetal ring.
