| dc.description.abstract | Laggera tomentosa in the family of Asteraceae, is a species endemic to Ethiopia. It has medicinal values and is important in the traditional medicine like the other species in the genus. In this project work, one sesquiterpene and one flavone, namely 3-(3’-acetoxy-2’-hydroxy-2’-methylbutyryl)cuauhtemone (LTE-1) and 4’, 5,7-trihydroxy-3’,3,6-trimethoxyflavone (LTE-2) were isolated from the aerial parts of the plant, respectively. LTE-1 was isolated before from the same plant and other species of Laggera. LTE-2 was reported before from Jasona montana plant growing in Egypt and Mentha royleana with the name Jaceidin. However, it was isolated for the first time from L. tomentosa. The structures were elucidated based on NMR and UV spectra and by comparison of the data obtained with those reported for related compounds in the literature | en_US |
