Abstract: The nutrient compositions extracted from Siraitia grosvenorii in the middle and high altitude hilly region at northern Guangxi (Longsheng autonomous county, Guilin city) were analyzed and compared with Yongfu and Xiangxi county, contents of ash, total sugar, protein, crude fiber, fat, vitamin C(VC), vitamin E(VE) and amino acid were determined. Results showed that the contents of ash, total sugar, protein, crude fiber, fat, VC and VE were (7.59±1.05)%, (59.99±6.33)%, (21.26±1.68)%, (63.25±5.01)%, (0.09±0.02)%, (38.00±3.06) mg/100 g and (0.61±0.02) mg/100 g. Contents of protein, VE and fat from Siraitia grosvenorii in Longsheng were higher than that of Yongfu with 7.37%, 3.39% and 12.50%, the contents of total sugar, crude fiber and ash from Siraitia grosvenorii in Longsheng were 59.99%, 63.25% and 7.59% which were lower than Yongfu with 66.70%, 69.16% and 8.72%. The contents of ash, total sugar, protein, crude fiber and VC in Siraitia grosvenorii of Longsheng were 1.61, 1.99, 2.46, 1.38 and 4.85 times of the maximum contents of related components in Xiangxi county. There were 17 kinds of amino acids in Longsheng Siraitia grosvenorii, contents of total amino acids were 8.20%, 7 kinds of human body essential amino acids were 31%. There was no significant difference in contents of amino acids in Siraitia grosvenorii between Longsheng and Yongfu. Siraitia grosvenorii is rich in nutrient,which has high protein content, amino acid and VC. It shows higher nutritional value and is suitable for expanding and large-scale planting in the middle and high altitude hilly region at northern Guangxi.

Key words: Siraitia grosvenorii, amino acids, nutrient composition, Longsheng autonomous county
