Analysis of Nutritional and Functional Components of Edible Young Leaves and Adult Old Leaves of Dendropanax dentiger

In order to understand the nutritional value and functional properties of Dendropanax dentiger, nutrients such as protein and functional substances such as flavonoids were determined and analyzed. The results showed that the water content of edible young leaves and adult old leaves were 82.7% and 73.7%, respectively, and the dry-fresh ratios were 1∶5.78 and 1∶3.80, respectively. Counted as fresh leaves, the crude protein contents were 4.24 and 2.76 g·100 g⁻¹, the crude fat contents were 0.38 and 0.72 g·100 g⁻¹, the total soluble sugar contents were 12.17 and 25.38 mg·g⁻¹, the cellulose contents were 25.36 and 64.41 mg·g⁻¹, the total organic acids were 0.5176 and 0.1655%, and the free amino acids were 6.594 and 1.102 mg·g⁻¹, respectively. Vitamin A16.08 and 26.34 μg·g⁻¹, vitamin C508.35 and 422.24 μg·g⁻¹, vitamin E15.70 and 32.77 μg·g⁻¹, total flavonoids 3.466 and 1.668 mg·g⁻¹, total polyphenols 1.232 and 0.580 mg·g⁻¹, as well as rich phosphorus, potassium, calcium, magnesium, sodium, iron, manganese, zinc, selenium mineral elements, rich in nutrients, In particular, it contains more abundant flavonoids and polyphenols of plant functional compounds, and the content of nitrate and nitrite is also low, which is a typical woody vegetable with medicinal and edible dual-purpose or dietary and health care functions, which is worthy of development and utilization.
