摘要
野生大豆主产于中国,古时为珍贵药材,但现代将其作药用的研究较少。以同样种植条件下收获的野生大豆、黑豆和大豆为材料,用HPLC法、凯氏定氮法和索氏残渣法分别测定其大豆异黄酮、蛋白质和脂肪含量,以此比较野生大豆、黑豆和大豆的药用价值。结果表明:12种大豆异黄酮类组分的总含量大小顺序为:野生大豆>黑豆>大豆;野生大豆和黑豆中黄豆苷和染料木苷含量特别突出,而且其相应的苷元含量也较高,大豆中则是丙二酰基化的黄豆苷和丙二酰基化的染料木苷含量特别突出,而其相应的苷元组分含量极低;相关性分析表明三种大豆的不同品种,大豆异黄酮总含量与其百粒重和脂肪含量呈极显著负相关,但与蛋白质含量的相关性不显著。结果说明野生大豆的药用研究应受到重视。
The wild soybean（ Glycine soja） mainly distributes in China, and it is used as a precious medicinal material in ancient times ,but its medicinal application is nearly neglected in modern time. To compare the medical value among wild, black and yellow soybeans, different varieties of wild, black and yellow soybeans were cultivated under same conditions, and isoflavones, protein and lipoid content were determined with HPLC, Kieldahl method and Soxhlet residual method, respectively. The results showed the total isofiavones content was in the order of wild 〉 black 〉 yellow soybeans ;the contents of daidzin and genistin were much higher than other isofiavone components in wild and black soybeans, while the contents of 6＂-o-malonyldaidzin, 6＂-o-malonylgenistin were much higher in yellow soybeans;the contents of daidzein and genistein were relatively higher in wild and black soybeans than in yellow soybeans. By correlation analysis, in the different varieties of wild,black and yellow soybeans, the total isoflavones content was negatively significantly correlated with 100-seed weight and lipoid content, while its correlation with protein content was not significant. So it is suggested that the wild soybean should be thought highly as an important medicinal material.
