Abstract
Corilagin is a promising anticancer drug candidate. Acer nikoense and A. ammonium are both known to contain corilagin. To explore whether corilagin occurs in congeneric species and to fully develop the medicinal value of maple, the corilagin content in different varieties of maple was determined by Ultrahigh-Performance Liquid Chromatography (UPLC). Acer buergerianum leaves contained corilagin and the corilagin content in leaves of different varieties at the deciduous stage varied from 1.2371 to 6.8887 mg/g, with an average of 4.3791 mg/g. Among the cultivars, 'Xingwang' and 'Qianlihong' showed relatively high corilagin contents and the content in 'Qilujin' was the lowest. The range of corilagin contents at the new leaf stage was 8.7452~11.2441 mg/g. Many parts of A. buergerianum contained corilagin, with the highest content in the leaves; based on this considerable corilagin concentration, this plant can be developed into raw material for corilagin extraction. There are large differences among varieties. To increase the output value and efficiency, it is necessary to further screen high-content varieties for industrial production; harvesting can be performed in spring and autumn, with autumn as the main season and spring as a supplemental season.
