Kaempferol-3-O-gentiobioside, the major flavonoid glycoside in Indonesian Cassia alata was quantified in various parts of the plant. The mature leaf was found to contain the highest content of this metabolite. A decrease of the flavonoid content in the juvenile leaf during the period of October through December was also observed. The contents ranged from 2.0 to 5.0% and 1.0 to 4.0% in mature and juvenile leaves, respectively. The other parts studied were flower (sepal and petal), rachis, stem and seed. Kaempferol-3-O-gentiobioside was not detected in the seed.
山柰酚-3-O-龙胆二糖苷是印尼翅荚决明中的主要黄酮糖苷，已对该植物的各个部位进行了定量分析。发现成熟叶片中这种代谢物的含量最高。在10月至12月期间，还观察到幼叶中黄酮含量有所下降。成熟叶和幼叶中的含量分别为2.0%至5.0%和1.0%至4.0%。研究的其他部位包括花（萼片和花瓣）、叶轴、茎和种子。种子中未检测到山柰酚-3-O-龙胆二糖苷。
