Abstract

The GC-MS analysis of fractions of methanol extract of stem of Cuscuta reflexa (Family Convolvulaceae) was carried out using a THERMO TRACE 1300 Gas Chromatograph equipped and coupled to a mass detector THERMO TSQ 8000 spectrometer with an TG 5MS (30 m × 0.25 mm, 0.25 μm) of capillary column. Database of National Institute of Standards and Technology (NIST) library was used to identify the components. GC-MS revealed two known compounds i.e. 2-Methoxy-4-vinyl phenol (6.80%) and Benzofuran-2,3-dihydro (20.89%) and other 12 unknown compounds such as 3,5-di-tert-Butyl-4-hydroxyanisole (35.50%); Hexatriacontane (12.02%); n-Hexadecanoic acid (10.12%); Scoparone (7.97%); Hexadecanoic acid methyl ester (5.22%); 1,3-Benzenediamine, N, N, N′, N′ tetramethyl- (15.43%); Phenol, 4(3-hydroxy1propenyl), 2-methoxy (9.31%); Phenol, 2,4 bis (1,1dimethylethyl); 2,3,5,6-Tetramethyl para phenylene diamine (14.18%); Retinoic acid-5,6-epoxy-5,6-dihydro (20.46%); 2,4-Dihydroxy-2,5-dimethyl-3(2H)furan-3-one (10.13%); 2,3-dihydro-3,5-dihydroxy-6-methyl-2-Propyl-tetrahydro-pyran-3-ol (10.13%); Pregn-4-ene-18-oic acid (5.75%) as some of the major compounds in its different fractions. Retinoic acid-5,6-epoxy-5,6-dihydro found as major compound may be responsible for blood glucose lowering potency.
