Abstract
Two new lignans (1 and 2) having a diarylhydroxybutyrolactone skeleton were isolated from the leaves of Trachelospermum lucidum (D. Don) Schum. Their structures were elucidated to be apocynotrachelolegnin 5′-O-β-d-glucopyranoside (1) and rafanotrachelogenin 4-O-β-d-glucopyranoside (2) on the basis of spectroscopic analysis. Two known lignans, matairesionoside-4-O-β-d-glucoside (3) and trachelosiaside (4), were also isolated from Trachelospermum lucidum.
