Abstract

This paper deals with the detailed phytochemical evaluation of the stem of Eclipta alba (Bhringaraja) family: (Compositae). The preliminary phytochemical screening shows that different extracts of plant have different constituents like carbohydrate, alkaloids, phenolics, steroids, glycosides, fat and oils. TLC of the hexane extract after column extraction was shown R_f value 0.78 in Petroleum ether:Hexane:Chloroform:Methanol, used as mobile phase in 2:4:2:1 ratio and TLC of pet. Ether extract also shown R_f value is 0.72 in Petroleum ether:Hexane:Chloroform, used as mobile phase in 4:3:1 ratio after column extraction. This is evaluated by the instrumental analysis (UV, IR, and NMR) of hexane and pet. Ether extract. They shows consequently that pet. Ether extract contains alkane (2940 Cm^-1, δ 0.827), alkene (1630 Cm^-1, δ 1.253-1.351), monomer of aliphatic acid (1760 Cm^-1 δ 2.169), aromatic amine (1570 Cm^-1, δ 2.593) etc. and hexane extract contains alkane (2940 cm^-1, δ 0.801-0.873) alkene (1625 Cm^-1, δ 0.988-1.075) aldehyde (1740 Cm^-1, δ 2.154 – 2.288) and aromatic alcohol (1110Cm^-1, δ 5.324). These data suggests that the extracts (pet. ether and hexane) may have the glycoside, aliphatic acid, steroids, fats and oils. They are pharmacologically important.

Abstract

A strong demand of a separate time zone by northeast populace has been a matter of great debate for a very long period. However, no implementable solution to this genuine problem has yet been proposed. The CSIR-National Physical Laboratory, CSIR-NPL (the National Measurement Institute, NMI, o f India and custodian o f Indian Standard Time, IST) proposes an implementable solution that puts the country in two time zones: (i) IST-I (UTC + 5: 30 h, represented by longitude passing through 82 °33 E) covering the regions falling between longitude 68 °7 E and 89 °52 E and (ii) IST-II (UTC + 6: 30 h, represented by longitude passing through 97°30E) encompassing the regions between 89°52E and 97°25E. The proposed demarcation line between IST-I and IST-II, falling at longitude 89 °52 E, is derived from analyses o f synchronizing the circadian clocks to normal office hours (9: 00 a.m. to 5 : 30p.m.). This demarcation line passes through the border of West Bengal and Assam and has a narrow spatial extension, which makes it easier to implement from the railways point o f view. Once approved, the implementation would require establishment of a laboratory for ‘Primary Time Ensemble - I I ’ generating IST-II in any o f the north-eastern states, which would be equivalent to the existing ‘Primary Time Ensemble-I’ at CSIR-NPL, New Delhi.
