以胆木叶为原料,分别对它的水分、粗蛋白、脂肪、还原糖、可溶性固形物、氨基酸、Vc、微量元素、单宁、总黄酮、总黄酮甙、生物碱的含量进行分析测定。研究结果表明:胆木叶营养丰富,其中脂肪、蛋白质和水分的含量较高,人体必需氨基酸含量为4.72%,占氨基酸总量的43.92%,而还原糖和可溶性固形物的含量则较低。在所测定的几种微量元素中,只有Se未检出,但K、P和Ca的含量丰富,特别是钾含量高达2.36%,而钠含量仅46.50mg/kg,这种高钾低钠特性,是预防高血压的一种良好食物来源。其中Mn、Mg、Fe含量也非常丰富,分别达到了517.70、460.00mg/kg和140.50mg/kg。而胆木叶中功能性成分以总黄酮、总黄酮甙和生物碱的含量较高,尤其是生物碱的含量高达3.46%。表明胆木叶是一种富含营养的植物原料。
The contents of water, crude protein, fat, reducing sugars, soluble solids, amino acids, Vc, trace elements, tannins, total flavonoids, total flavonoids, and alkaloids were analyzed and determined from the raw materials of bile wood leaves. The results showed that: Bile wood is rich in nutrients, including high levels of fat, protein and moisture, the body’s essential amino acid content of 4.72%, accounting for 43.92% of total amino acids, while the content of reducing sugars and soluble solids is lower. Of the trace elements measured, only Se was not detected, but K, P, and Ca were abundant, especially the potassium content was as high as 2.36%, while the sodium content was only 46.50 mg/kg. This high potassium and low sodium characteristic Is a good food source for preventing hypertension. The contents of Mn, Mg, and Fe were also very rich, reaching 517.70, 460.00 mg/kg, and 140.50 mg/kg, respectively. The functional components of Biloba leaves were higher in total flavonoids, total flavonoids and alkaloids, especially the alkaloid content was as high as 3.46%. It shows that the bilewood leaf is a kind of nutrient-rich plant material.
