Evaluation Of The Quality Ofprotaetia Brevitarsislarvae Through Amino Acid-Activity Relationship

Detection of primary metabolites such as amino acids, carbohydrates along with the secondary metabolites is important for the quality control of herbal. Therefore, a simple amino acid analysis method was investigated for the quality control ofProtaetia brevitarsis. Six batches ofP. brevitarsiscollected from different feeding batches were used to analyze the amino acid composition and content. The amino acid composition was consistent in the six batches ofP. brevitarsis, and the amino acid content of six batches ofP. brevitarsiswas also relatively stable. Under these conditions, the six batches ofP. brevitarsisalso possessed stable antioxidant activity. The stable composition and content of the amino acids could guarantee the stable antioxidant in batch-to-batch ofP. brevitarsis. So, the amino acid-activity relationship as an effective method can be used to assess the quality ofP. brevitarsis.
