槐花米为植物Sophorae japnica L.的花蕾,生药名槐花米(Flos sophorae japonica)。中医师用作治痔疮及止血药,据中外化学家研究,含黄酸素蘆艼,又据药理学家研究,蘆艼能减少微血管脆性,可治高血压症。查槐花米的化学成分研究,有悠久的历史,迄今巳有七十余年,但仍有继续研究者。历年来世界化学家对于蘆艼化学研究,构造式巳决定;但对于由槐花中提出黄龄素,仅在提得与蘆艼有些相似性质,即认定槐花中所得黄龄素系蘆艼,至于由槐花中提得黄龄素的分离、精制、物理性贸及构造式研 Flos sophorae japonica is the flower bud of the plant Sophorae japnica L. Chinese medicine practitioners used to treat hemorrhoids and hemostatic drugs. According to research by Chinese and foreign chemists, containing lutein reeds, and according to pharmacologists research, reed can reduce microvascular fragility, can cure hypertension. The study of the chemical constituents of Zhanhua Huami has a long history, and so far there have been more than 70 years, but there are still continuing researchers. Over the years, the world’s chemists have studied the structure of reeds and decided to adopt structural formulas. However, for the purpose of formulating yellow pigments from the flowers, they are only similar to those obtained from reeds, that is, they are identified as reeds obtained from the flowers. , As for the separation, purification, physical trade, and structural research of yellow pigment extracted from the flowers
