Identification of Nutritional Ingredients and Medicinal Components of Hawk Tea and Insect Tea Using Widely Targeted Secondary Metabolomics

Abstract

In this study, the metabolites in insect tea and hawk tea were analyzed by ultra-high performance liquid chromatography–triple quadrupole mass spectrometry. We found 49 metabolites in insect tea and hawk tea that can be used as key active components in traditional Chinese medicine, as well as 98 metabolites that can be used as active components of pharmaceutical preparations for the treatment of cancers, hypertension, cardiovascular diseases, etc. Comparative analysis found that insect tea and hawk tea had significant differences in their metabolic profiles. Insect tea contains more metabolites beneficial to human health than hawk tea; insect tea also has higher antioxidant activity in vitro than hawk tea. The results of this study will contribute to the development of new health foods using insect tea.

Comparative Metabolome Profiling for Revealing the Effects of Different Cooking Methods on Glutinous Rice Longjing57 (Oryza sativa L. var. Glutinosa)

“…Similarly, the changes in antioxidant and metabolic substances in peach fruits were investigated during ripening using metabolomics to reveal the mechanism of fruit quality formation [ 18 ]. The widely targeted metabolome offers extensive analytical information due to its high coverage and accurate relative quantification, making it effectively applicable to various food materials [ 19 ], including tea [ 20 ], potato [ 21 ], and durian [ 22 ]. The chemical variations in high oleic acid peanut seeds treated using three domestic cooking approaches have been characterized using widely targeted metabolomic analysis to elucidate the bioactive substances in cooked peanuts [ 23 ].…”
