Nutritional component analysis and resourceful value evaluation of the pericarp and seed of Zanthoxylum bungeanum

Based on the concept of resourceful chemistry of Chinese medicinal materials, the nutritional components, such as polysaccharides, monosaccharides and oligosaccharides, proteins and amino acids, nucleosides in the pericarp and seed of Z.bungeanum were analyzed by sulfuric acid-phenol colorimetry, liquid chromatography, Kjeldahl and liquid chromatography-mass spectrometry methods to discover their potential values.The results showed that the pericarp of Z. bungeanum was rich in soluble polysaccharide ( 96.33 mg/g) and proteins ( 92.32 mg/g) nutrients, and the protein amino acid.The proportion of protein amino acid composition was close to that of human body with high nutritional value.The contents of soluble polysaccharide and proteins were relatively low, while the content of nucleosides was relatively high ( 3.94 mg/g) . Based on the composition and distribution of nutrient substance contained in the fruits of Z.bungeanum, fine utilization strategy was proposed for extending the industry chain of Z.bungeanum resources and reducing the waste in the deep processing of Z.bungeanum resources.This study clarified the distribution, composition and content of nutrient components in the fruit of Z. bungeanum, which could provide support for the healthy development of Z.bungeanum resource industry.
