AI Article Synopsis
- Researchers refined a 95% ethanol extract from Rosa cymosa root using column chromatography techniques, isolating a total of eleven triterpenes.
- The triterpenes’ structures were identified using spectroscopic methods, naming them including pomolic acid, ursolic acid, and ilexoside B.
- Notably, some compounds were newly identified from this plant and also from the genus for the first time, highlighting the significance of these findings in botanical research.
Article Abstract
The constituents in 95% ethanol extract of the root of Rosa cymosa Tratt were purified by column chromatography techniques, leading to isolation of eleven triterpenes. Their structures were elucidated by spectroscopic data as pomolic acid (1), fupenzic acid (2), ursolic acid (3), euscaphic acid (4), arjunic acid (5), tomentic acid (6), 3β-E-feruloyl corosolic acid (7), 1β-hydroxyeuscaphic acid (8), myrianthic acid (9), cecropiacic acid (10), and ilexoside B (11). Among them, compounds 3, 6-8, 10 and 11 were obtained from this plant for the first time, and compounds 7 and 10 were obtained from this genus for the first time.
