THE VOLATILE COMPONENTS OF INDIAN LONG PEPPER, PIPER LONGUM LINN.

摘要

As part of IFFs continuing program of looking at unusual natural products we recently analyzed Piper longum L. (Long pepper). This is a slender aromatic climber with perennial roots occurring in various parts of India. The dried spikes are 1-3 cm long, 4-6 mm in diameter and are grayish to dark in color. The fruits/spikes are pungent and have a pepper like flavor. Long pepper is used as a spice and in pickles and preserves. It is also used to treat bronchial trouble and as a carminative and analgesic. Numerous terpene and sesquiterpene compounds were identified, along with a number of dienamides. Several of these amides were identified in Piper longum for the first time and from synthesis studies we were able to show that individual amines imparted, to a lesser or greater extent, a 'tingle effect', when tasted.
