AI Article Synopsis
- Five compounds were isolated from the seeds of Momordica charantia, and their structures were determined using various spectral and chemical methods.
- The compounds were identified as vacine, mycose, 3-O-(beta-D-glucopyranosyl)-24 beta-ethyl-5 alpha-cholesta-7, trans-22E, 25 (27)-trien-3 beta-ol, momorcharaside A, and momorcharaside B, with mycose being a first for this plant.
- Additionally, compound IV showed significant inhibition of DNA and RNA synthesis in S 180 tumor cells during early pharmacological tests.
Article Abstract
Five compounds were isolated from the seeds of Momordica charantia. This paper reports their structure determination by spectral (IR, UV, HNMR, CNMR, and MS) and chemical methods. The structures of I, II, III, IV and V were elucidated as vacine, mycose, 3-O-(beta-D-glucopyranosyl)-24 beta-ethyl-5 alpha-cholesta-7, trans-22E, 25 (27)-trien-3 beta-ol, momorcharaside A and momorcharaside B respectively. Mycose was the first time found in this plant and compound III was the first time found in the genus Momordica. IV and V were new compounds. IV exhibited obvious inhibition of DNA and RNA syntheses in S 180 tumor cells in preliminary pharmacological studies.
