ISOLATION AND IDENTIFICATION OF TERPENOID COMPOUNDS FROM n-HEXANA EXTRACT OF PERMOT PLANT BRACTS (Passiflora foetida L)

Isolation and identification of terpenoids compounds from n-hexane extract of permot bracts plants (Passiflora foetida L.) has been done. Crude powder of the bracts permot plants were macerated with n-hexane. Fractionated of n-hexane extract on a vacuum liquid chromatography to afford three fractions (A, B and C). Purification of fraction B with TLC preparative to afford isolate B1 and B2.. A compound of spectra UV-Vis B1 indicating the presence of conjugation of double bond (C=C), furthermore the IR spectra showed vibration for - OH group, C=O of the ester group, C-O group, and methyl group (-CH 3 ) in position gem dimethyl.  1 H-NMR spectra showed the signal from methoxy group (OCH 3 ), olefin protons (-CH=CH-), protons in carbon to the oxygenation (C-OH), two units gem dimethyl, and three methyl group (-CH 3 ).  13 C-NMR spectra showed the signal from carbon aliphatic group, carbon carbonil (C=O) of the ester group, double bond carbon (C=C), and carbon to the oxygenation (C-OCH 3  and C-OH)). Based on the analysis of UV-Vis, IR,  1 H-NMR, and  1 H-NMR spectrocopies data, isolate B1 is suggested from terpenoids type triterpenoids pentacyclic that conjugation of double bond and ester group. Keywords :  Terpenoids, triterpenoids pentacyclic, permot (Passiflora foetida L.), and n-hexane extract.
