Abstract
ABSTRACT Yields of press juice for Hippophae rhamnoides ssp. sinensis and ssp. mongolica cv. Indian Summer were 69.2% and 62.8%, respectively. Centrifugation of the press juices at 4C, 4480 × g for 15 min provided yields of cream, serum and pellet of 1.72, 95.6 and 0.68% for ssp. sinensis, and 5.4, 92.3 and 0.32% for ssp. mongolica cv. Indian Summer. All percentages are percentage (w/w). The particulate of each juice was characterized microscopically and the particulate of cv. Indian Summer was much larger than that of ssp. sinensis. Much more oil was apparent microscopically in the cv. Indian Summer cream as expected from the yield data mentioned above. Pellet material was not distinguishable between the two ssp. Trichomes were visualized in greater detail, a particular particle that may be exclusive to cv. Indian Summer was described and the presence of crystalline material in aggregated particles was observed.
