Oleanane-type triterpenoid saponins from Camellia petelotii leaves and their hyaluronidase inhibitory activity.
Seven previously unreported oleanane-type triterpenoid saponins (1-7), along with three known compounds (8-10), were isolated from the leaves of Camellia petelotii. Their structures, including the relative configurations of the aglycone moieties, were elucidated through comprehensive spectroscopic analysis, including e...
