(CCSHAU, 2005) Chawla, Rajesh Kumar; Rajvir Singh
Eclipta alba is a common weed of rice field, belonging to family compositae, mostly inhabiting tropical and sub tropical region of the world ascending upto 6000 ft on the hills. The plant is known for its anti-inflammatory, anti-pyretic, anti-hypertensive and anti-ulcer properties. Plant of E. alba collected from different places, CCS Haryana Agricultural University, Hisar were extracted with hot methanol. Column chromatography of the extractive over silica gel afforded five compounds. Three of these, were, 1-Hentricontanol, β-sitosterol and wedelalactone, already reported. Other compound isolated from E. alba were 17-tritriacontanon and Hirtin. Hirtin and 17- tritriacontanone are being reported for the first time from E. alba. Isolated compounds were characterized on the basis of IR, 1H-NMR, mass spectral data and other properties of the compounds and their derivatives. The identities of some of the compounds were confirmed by direct comparisons with the authentic samples.
