After studying the optimal extraction process of BME, we carried out amplification experiments according to the optimal process by a large ball milling machine (Retsch, PM100). In each kilogram of dried mangosteen pericarp, the content of sixteen xanthones can reach 23.87 g/kg. Therefore, BME was considered a reliable method, either as a ...
