Two amphoteric galactocerebrosides possessing a tri-unsaturated long-chain base from the leech (Hirudo nipponica)

Six amphoteric galactocerebrosides were isolated from the land annelid (Hirudo nipponica). Two of them have a tri-unsaturated long-chain base, D-erythro-(4E,8Z,11Z)-docosasphingatrienine. The position and geometry of the double bonds in the long-chain base unit were determined on the bases of chemical and spectral data.

Dammarane triterpenoids from Carnauba, Copernicia prunifera (Miller) H. E. Moore (Arecaceae), wax

Phytochemical investigation from carnauba (Copernicia prunifera) wax led to the identification of sixteen dammarane–type triterpenes, including thirteen new characterized as: (24R*)-methyldammara-20,25-dien-3α-ol and a mixture of alkyl (24R*)-methyldammar-25-en-20-ol-3β-carboxylates, together with three previously described triterpenes: carnaubadiol, (24R*)-methyldammara-20,25-dien-3β-ol and (24R*)-24-methyldammara-20,25-dien-3-one. Moreover, four fatty alcohols (eicosanol, docosanol, tetracosanol and hexacosanol) as well as four sterols (cholesterol, campesterol, stigmasterol, and sitosterol) were also obtained. These compounds were isolated using classical chromatographic methods and their structures were determined by spectroscopic and chemical methods.
