Nutritional Composition and Distribution of Heracleum dissectum Ledeb. at Different Growth Stages

摘要

Heracleum dissectum Ledeb.（HD） with high edible and medicinal values is distributed in Northeast Asia.To provide a reference for selecting appropriate parts and periods to harvest HD,the nutrient contents in different parts of HD at three growth stages were determined.The nutrients being determined are essential nutrients closely related to human needs,and the crude protein content of HD was 3.58-28.43 g·100 g^-1 DW （dry weight）,sugar content was 2.33-30.92 g·100 g^-1 DW,and soluble dietary fiber content was 9.71-26.09 g·100 g^-1 DW.Crude protein was mainly distributed in leaf blades and inflorescences,sugar was primarily found in roots,and dietary fiber was predominantly located in leaves.From the leaf development stage to the flowering stage and then to the late seed harvest stage,the content of moisture,crude protein and soluble sugar first decreased and then increased.In contrast,the content of dietary fiber and crude fat first increased and then decreased.
