New limonoids from Harrisonia perforata (Blanco) Merr

Two minor compounds were isolated from a sample of Harrisonia perforata leaves collected in central Vietnam, namely haperforin B1, C27H32O9, and haperforin D, C27H34O10. Biogenetically, haperforin D and haperforin B1 can be derived from each other by addition or elimination of water.
