New Monoterpenoids from Fruits of Gardenia jasminoides var. radicans

One new lactone, cyclopentanepyrone A (1), and two new monoterpenoids, gardeterpenone A (2) and jasminoside V (3), were isolated from the fruits of Gardenia jasminoides var. radicans, along with four known monoterpenoids, 4 - 7, which were isolated from this plant for the first time. The structures of the isolates were elucidated by extensive spectroscopic studies, including UV, IR, 1D- and 2D-NMR, ESI-MS, HR-ESI-MS, and CD experiments.
