  Phytosterols in Sea Buckthorn (Hippophaë rhamnoides L.) Berries:  Identification and Effects of Different Origins and Harvesting Times

  摘要：

  Sterols in seeds, pulp/peel fractions, and whole berries of sea buckthorn (Hippophae rhamnoides L.) samples belonging to two major subspecies (sinensis and rhamnoides) from Finland and China were analyzed as TMS derivatives by gas chromatography-mass spectrometry after saponification of the oils. The total sterol contents, in the seeds, the fresh pulp/peel, and the whole berries were, 1200-1800, 240-400, and 340-520 mg/kg, respectively. The corresponding values in the extracted oils were 12-23, 10-29, and 13-33 g/kg. Sitosterol constituted 57-76 and 61-83%, respectively, of the seed and pulp/peel sterols. The sterol content and composition showed little variation between subspecies and collection sites. Different harvesting dates showed significant effects on the levels of some sterols both in the seeds and in the pulp/peel. The sterol profiles obtained are useful for characterizing sea buckthorn and detecting adulterations of the valuable oils. The information provided by the present investigation is also important for further chemical investigation of sea buckthorn sterols and industrial utilization of the berries as a raw material of functional foods.
