Abstract
One new diterpernoid glycoside, lanceolatinoside A (1), together with one known iridoid glycoside, luzonoside C (2) were isolated from the fruit of Forsythia suspensa. The structure of the new compound (1) was elucidated through 1 D and 2 D NMR spectroscopic data, and HR-ESIMS. Compound 2 was identified as luzonoside C (2) on the basis of NMR spectroscopic data analyses and comparison with those reported in the literature.
