Pseudopelletierine is the main alkaloid derived from the root-bark of the pomegranate tree (Punica granatum), along with at least three other alkaloids: pelletierine, isopelletierine, and methylpelleteirine (C9H17ON), which yield 1.8, 0.52, 0.01, and 0.20 grams per kilogram of raw bark. Isopelletierine is optically inactive.[1]

It is a homolog of tropinone, and can be synthesized in a manner analogous to the classical Robinson tropinone synthesis, using glutaraldehyde (rather than succinaldehyde), acetonedicarboxylic acid, and methylammonium chloride.[2]

Pelletierine sulphate is used medicinally in Iraq as an anthelmintic and anti-amoeboid. It triggers, like strychnine, a stimulant reflex, which is effective against tapeworms, ring worms and nematodes. Simple bark-extracts have recently been shown to be effective in vitro against the intestinal bacteria salmonella typhi, vibrio cholera, herpes simplex, HIV, and tumors.[3][4][5][6]
