The ethyl acetate fraction (81 g) was subjected to column chromatography over silica gel eluting with n-hexane, n-hexane-ethyl acetate, ethyl acetate, ethyl acetate-methanol in increasing order of polarity to get ten fractions (V1-V10).The Fraction V5 (6 g) obtained with n-hexane: ethyl acetate (4: 6) was further chromatographed on silica gel column eluting with n-hexane: ethyl acetate to get 3 sub-fractions VS1-VS3.
n-Hexane extracts: The dried extract of each sample was taken in a beaker and 100 mL of methanol was added in each, shaken well and transferred to 250 ml separating funnel.

The working standard mixtures of PCDDs congeners 1-4 for spiking were separately prepared in n-hexane from the stock standard solutions as per requirement (Table 2) to determine% recoveries of congeners.
The solvent was evaporated under reduced pressure and dissolved in water and partitioned with n-hexane, chloroform, and ethyl acetate, in that order.
In vitro results showed that chloroform fraction at concentration of 100 ug/ml showed maximum [alpha]-amylase inhibition (53.11 +- 0.97% with IC50 value of 93.61 +- 4.44 ug/ml) followed by ethyl acetate, n-hexane and n-butanol fractions.
Zingiber officinale Rosc, known as the medicinal plant [12], had moderate antibacterial activity (11.9 to 13.0 mm) against Clostridium perfringens in n-hexane, Chloroform, ethyl acetate, and butanol extract fractions.
Crude extract was dissolved by aquadest (100 ml) and fractionated by liquid-liquid fractionation by n-hexane and ethyl acetate (each 100 ml x 3) respectively and both evaporated in vacuum to get n-hexane and ethyl acetate fractions.
N-hexane solvent was used for the preparation of samples and ascorbic acid was used as standard in this study.
From 20 g of viscous extract, three fractions were obtained, i.e., 8.98 g of water fraction with rendement 44.9% (w/w), 0.18 g of n-hexane fraction with rendement 0.9% (w/w), and ethyl acetate fraction as much as 5.53 g with Randement 27.65% (w/w).
