Research context and aims: Cassia angustifolia is a valuable medicinal plant that has been studied by scientists around the world for a long time. For our country, it seems that this plant is still very new, but now it has been planted in Tuy Hoa, Phu Yen and initial researches in the country about this plant have been made. This plant is used to treat stools, constipation, indigestion, lobed lateral abdominal and so on Many studies have demonstrated the laxative of anthraglycoside compounds derived from this plant as aglycol anthranoids (rhein, Aloe-emodin, and chrysophanol) and anthraglycosides (rhein monoglycoside, Aloe-emodin mono glycoside, sennosid A, B, C, D, G, and Aloe-emodin dianthron glycoside). In this scientic article, the pure anthraglycoside compound Aloe-emodin was isolated from 2.5 grams of total leaves of Cassia angustifolia Vahl. Their chemical structures are elucidated by analytical methods (IR, UV, MS, 1H-NMR) to determine the Aloe-emodin.
Results: Develop a process to extract Aloe-emodin from senna; Isolate and determine the structure of Aloe-emodin from senna; Develop a process of preliminary quatification of Aloe-emodin tracers in senna.
