• Trachelospermum jasminoides
• 5-Methoxytracheloside
• 5-Methoxytrachelogenin

Two novel 5-methoxydibenzylhydroxybutyrolactone lignans named 5-methoxytracheloside and 5-methoxytrachelogenin were isolated from the stems and leaves of Trachelospermum jasminoides (Lindl.) Lem., their structures were determined as (8S, 8'S)-8'-hydroxy-3, 3', 4, 5-tertramethoxylignan-9, 9'-olide-4'-O-beta-D-glucopyranoside and (8S, 8'S)-4', 8'-dihydroxy-3, 3', 4, 5-tertramethoxylignan-9, 9'-olide by various spectroscopic analysis. 5-Methoxytracheloside was a new compound and 5-methoxytrachelogenin was isolated from natural source for the first time.
