Abstract:

In order to provide practical and theoretical basis for better development and use of the northeast forest ants resources, the author analyzed and determined the nutrition and compared the antioxidant components in two kinds of ants’ body (Polyrhachis vicina Roger and Formica truncicola Forel) in Fenglin national nature reserve of Lesser Khingan Range in Heilongjiang province. The results showed that: Polyrhachis vicina Roger and Formica truncicola Forel were all rich in nutrients, crude protein contents exceed all the reference classes of livestock and poultry food as well as fish food. The crude protein contents of Polyrhachis vicina Roger and Formica truncicola Forel were 62.4% and 56.6%, separately. By the variance analysis we can know, they two had significant difference (P＜0.01), the vitamin C contents were 23.0 mg/g and 23.2 mg/g, separately, this showed no significant difference (F=6.161, P＞0.05); the superoxide dismutase contents (SOD) of Polyrhachis vicina Roger was 73.5 U/mL, but the superoxide dismutase contents (SOD) of Formica truncicola Forel was 42.5 U/mL, that was to say SOD contents in Polyrhachis vicina Roger’s body were 72.94% higher than in Formica truncicola Forel. Similarly, the peroxidase contents (POD) of Polyrhachis vicina Roger was 7.1 U/mL, while the peroxidase contents (POD) of Formica truncicola Forel was 4.7 U/mL, that meant POD contents in Polyrhachis vicina Roger’s body were 51.06% higher than in Formica truncicola Forel. The conclusions were, Polyrhachis vicina Roger was more suitable as protein health food for development; the two kinds ants all had high antioxidant ingredients, can do the development and utilization for the pharmaceutical industry.
