ABSTRACT


hrough current phytochemical investigation on dichloromethane (DCM) fraction of 80% methanolic extract of Tricholepis eburnea, seven chemical constituents were isolated and their structures were elucidated by spectroscopic analyses. Two of them were identified as new flavonoids as trichonoide A (1) and trichonoide B (2), while the other five known constituents β-sitosterol (3), 3-O-acetyl-β-stigmastanol (4), 3β,17β,20-trihydroxy-l-oxo-(20R, 22 R)- witha-5,14,24-trienolide (5), pectolinaringenin (6), and dillenetin (7) were isolated for the first time from this species .
