    Phytochemical Investigation on the Leaves of Laggera Tomentosa (Petroleum Ether Extract)
    (Addis Ababa Universty, 2006-07) Amenu, Dibaba; Asfaw, Nigist (PhD)
    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
