Özet:Thesis (M.Sc. in Pharm)--Chulalongkorn University, 1990
The fresh leaves of Mitragyna speciosa (Korth.) Havil. Were examined for their alkaloids. Altogether nine alkaloids were isolated, six of which being heteroyohimbine alkaloids identified as mitragynine, paynantheine, speciogynine, mitraciliatine, ajmalicine, and tetrahydroalstonine. The other three being oxindole alkaloids identified as isopteropodine, isomitraphylline, and mitraphylline. Tetrahydroalstonine and isopteropodine have never been reported from this species before. The physical and chemical properties of these alkaloids were studies.
สามารถแยกได้แอลคาลอยด์ 2 ประเภท คือ heteroyohimbines และ oxindoles จากใบสดของต้นกระท่อม Mitragyna speciosa (Korth.) Havil., heteroyohimbines ที่แยกได้มี 6 ชนิด คือ mitragynine, paynantheine, speciogynine, mitraciliatine, ajmalicine และ tetrahydroalstonine ส่วน oxindoles ที่แยกได้มี 3 ชนิด คือ isopteropodine, isomitraphylline และ mitraphylline แอลคาลอยด์ tetrahydroalstonine และ isopteropodine ยังไม่เคยมีรายงานว่าพบในพืชชนิดนี้มาก่อน พร้อมทั้งได้ศึกษาคุณสมบัติทาเคมีและกายภาพของแอลคาลอยด์ทั้ง 9 ชนิด
