【 摘 要 】

Fruits ofLycium barbarumL. (wolfberry or “Gouqi” in Chinese) are widely used as traditional Chinese medicine and functional food in China, South-east Asia, Europe and North America. Polyphenols, polysaccharides and carotenoids are the main active compounds inL. barbarumfruits. Based on a rapid sample preparation with ultrasonic-assisted extraction (UAE) established, contents of polyphenols, polysaccharides and carotenoids ofL. barbarumfruits from 8 main producing areas of western China were analyzed and the related environmental factors were investigated. The results are:L. barbarumfruits from Zhongning showed the highest polyphenols contents (2.9749%) and the highest antioxidant activity (RSA = 56.82%), the highest content of polysaccharides (8.9041%) was from Jinghe, the highest content of carotenoids (0.1642%) was from Julu; the highest fruit weight and pulp weight were from Numhon. Contents of polysaccharides, polyphenols and carotenoids were significantly affected by environmental factors: the principle factor for polyphenols was soil organic matter (SOM) (r = 0.964), the principle factors for carotenoids were temperature-sunshine (r = 0.826), polysaccharides were mainly affected by soil available phosphorus (r = 0.75), fruit weight or pulp weight were negatively correlated with temperature (r = 0.953, 0.963). Each of the three active components has its own genuine producing area rather than Zhongning as the only genuine producing area authenticated.
