中文摘要： 分析贵州产九香虫Aspongopus chinensis Dallas体内的营养成分。结果表明：从江和习水产九香虫都具有丰富的营养，其中粗蛋白分别为350.9 mg·g-1和356.5 mg·g-1、粗脂肪432.6 mg·g-1和436.2 mg·g-1、粗灰分22.9 mg·g-1和22.8 mg·g-1；总氨基酸含量为334.3 mg·g-1和253 mg·g-1，其中必需氨基酸占总氨基酸的41.22%和33.34%，必需氨基酸与非必需氨基酸之比分别为0.70和0.50；九香虫体内脂肪酸多以油酸和软脂酸为主，其中油酸占总脂肪酸的49.48%和41.54%；含有丰富的矿物质和微量元素，尤其是Mg的含量达到1.26 mg·g-1和1.32 mg·g-1，且不含有对人体有害的Hg、Pb和As；含有多种维生素，其中维生素C含量最为丰富，为0.78 mg·g-1和0.79 mg·g-1。作为具有保健功能的中药昆虫，同时具有丰富的营养成分，九香虫是极具潜力的药食两用食品。
英文摘要： The nutritional components of Aspongopus chinensis Dallas in Congjiang and Xishui counties, Guizhou province were determined. The results show that A. chinensis from these two locations contained abundant nutrients; crude protein (350.9 mg·g-1 and 356.5 mg·g-1), crude fat (432.6 mg·g-1 and 436.2 mg·g-1) and ash (22.9 mg·g-1 and 22.8 mg·g-1). Total amino acid content of specimens from in Congjiang and Xishui was 334.3 mg·g-1 and 253 mg·g-1 respectively. Ratios of E/N in specimens from the two locations were 0.7 and 0.5, respectively. Some minerals and trace elements were particularly abundant; Mg was 1.26 mg·g-1 in specimens from Congjiang and 1.32 mg·g-1 in those from Xishui, with no Hg, Pb and As detected. Several kinds of vitamin were detected; Vitamin C was 0.78 mg·g-1 in Congjiang and 0.79 mg·g-1 in Xishui. A. chinensis is an insect food resource with good nutritional qualities.
