Secoiridoid and flavonoid glycosides from Gonocaryum calleryanum

, 2021
The leaves of Gonocaryum calleryanum afforded four new secoiridoid glycosides acylated with 2,3-dihydroxy-2-methylbutanoic acid, three of which have a novel 10-membered dilactone-ring. From this plant, we also isolated a new flavonoid glycoside, apigenin
