Abstract: Ginger (Zingiber officinale Roscoe) is a monocotyledonous, sterile cultigen thought to have originated in India or southeast Asia, from where it was introduced to other parts of the world.The ginger rhizome is one of the most common constituents of diets worldwide and is reported to possess antioxidant, anti-inflammatory, antiseptic and carminative properties (Afzal et al. 2001).Gingerols, pungent principles of ginger are biologically active components that may make a significant contribution towards medicinal applications of ginger.Gingerol, however, are thermally labile due to the presence of ß-hydroxy keto group and are converted under high temperature to [6]-, [8]-, and [10]-shogaols (Bhattarai et al. 2007).The content of the active principle is not uniform and can vary significantly between plant varieties and regions in which ginger is grown (Gruenwald 2004).So far, there has not been a systematic study on quantification of pungent principle in different genotypes grown and consumed in India.Hence a study was conducted during 2007-08 to explore the variability of different genotypes of Indian ginger in terms of their content of pungent phenolic compounds to identify high-yielding genotypes for commercial cultivation for flavour or pharmaceutical use.Eighteen genotypes of ginger, which were grown in different parts of India were selected.Some of them are released varieties while others are local genotypes that have the potential in terms of yield and pungency.These genotypes were grown in the experimental field of ICAR Research Complex for North Eastern Hill Region, Barapani, Meghalaya, India (latitude 26° N and 92° E, with an elevation of 950 m above mean sea level) in April during 2007-08.The soil was a sandy loam, acidic (pH 5.4), having an organic carbon content of 1.9%, with 286.97, 11.24 and 206.76 kg/ ha available N, P and K respectively.The genotypes were harvested after 9 months of planting.Fresh rhizomes were 70
