Abstract: The optimum extracting conditions of anthraqinones from Cassia tora L with the aid of ultrasonics were studied with the orthogonal test design.The results showed that when dousing the dried Cassia tora L powder with 85% ethanol(1 g in 10 ml)for 10 h,and with the aid of ultrasonic treatment for 25 min,the average extraction rate of total anthraqinone and free anthraqinone could reach 16.49 mg/g and 25.39 mg/g respectively.The ultrasonic assistant extraction method was superior over the traditional decocting method and the ethanol refluxing method.
