| dc.description.abstract | By means of chromatographic and crystallization techniques, two flavonoids, 6-hydroxy-5,7,8-trimethoxyflavanone (isopedicin) and 2’,5’-dihydroxy-3’-4’6’-trimethoxydihydrochalcone, and an alkaloid tetrahydroprotoberberine, 1,10-dihydroxy-2,3,9-trimethoxy-tetrahydroprotoberberine (capaurimine) were isolated from the stem bark of Fissistigma polyanthoides (DC.) Merr. The identification and structure elucidation of the isolated compounds were executed by analyses of the spectroscopic data. These compounds have never been reported to be found in this species before. | |
| dc.description.abstractalternative | จากการใช้วิธีทางรคงเลขและการตกผลิก สามารถแยกฟลาโวนอยด์ได้ 2 ชนิด คือ 6-hydroxy-5,7,8-trimethoxyflavanone (isopedicin) และ 2’,5’-dihydroxy-3’4’-6’-trimethoxy dihydrochalcone, และอัลคาลอยด์ในกลุ่ม tetrahydroprotoberberine คือ 1,10-dihydroxy-2,3,9-trimethoxy-tetrahydroprotoberberine (capaurimine) จากเปลือกต้นข่าหด (Fissistigma polyanthoides (DC.) Merr.) การพิสูจน์เอกลักษณ์และสูตรโครงสร้างทางเคมีของสารทั้ง 3 ชนิด ได้จากการวิเคราะห์ข้อมูลทางสเปคโตรสโคปี สารเคมีดังกล่าวยังไม่เคยมีรายงานว่าพบในพืชชนิดนี้มาก่อน | |
