Abstract
In this project, a phytochemical study of laggera tomentossa has been under taken and
chemical investigation on the solvent extract of the plant has been conducted.
The pet-ether extract of the leaves of L. tomentossa led to isolation of two Cuauthemone
type sesquiterpene compounds. The compounds were identified to be 4-OAcetylcuauthemone
3-O-angelate (LTP-1) and 4-O-Acetylcuauthemone3-O-(2’-methyl-
2’-hydroxy-3-acetoxy butyrate) (LTP-3). Structural determination was accomplished by
means of spectroscopic methods(UV,IR,1D,and 2DNMR). LTP-3 was identified as
cuauthemone sesquiterpenoides previously from Bluma alata
