Sophora Japonica Buds Extract

Sophora Japonica Buds Extract, also known as Sophora japonica extract or槐花提取物 in Chinese, is a natural substance derived from the unopened flower buds of the Sophora japonica tree, commonly referred to as the Japanese pagoda tree or Chinese scholar tree. This extract has garnered significant attention in various industries, including pharmaceuticals, cosmetics, and food, due to its rich composition of bioactive compounds and diverse applications. Botanical Background Sophora japonica is a deciduous tree belonging to the Fabaceae family, native to China and widely cultivated in East Asia, including Japan, Korea, and Vietnam. The tree is renowned for its ornamental value, with large, fragrant white flowers that bloom in summer. The unopened flower buds, known as "槐米" (Huaimi) in Chinese, are harvested during the summer before the flowers fully open. These buds are the primary source of Sophora japonica extract, which is obtained through various extraction methods, such as water or ethanol-based processes, to isolate the active constituents. Chemical Composition Sophora japonica buds extract is rich in flavonoids, particularly rutin (also known as sophorin or quercetin-3-rutinoside), which is the most abundant and significant component. Other flavonoids present include quercetin, kaempferol, and isorhamnetin, along with phenolic acids, terpenoids, and trace elements. The extract also contains a variety of other compounds such as alkaloids, steroids, and volatile oils, which contribute to its multifaceted biological activities.
