Thin-layer chromatographic and enzymatic spectrophotometric analyses have failed to detect uric acid in fecal extracts from American cockroaches on specified diets. Uric acid appears in the excreta when it is a dietary constituent, although most of it is apparently absorbed and stored internally. Surprisingly, ammonia is a major excretory product.
薄层色谱和酶分光光度分析未能检测到特定饮食的美洲大蠊粪便提取物中的尿酸。尿酸作为饮食成分出现时会出现在排泄物中，尽管大部分尿酸显然被吸收并在体内储存。令人惊讶的是，氨是一种主要的排泄产物。
