    Phytochemical Characterization of Some Ginger Cultivars from Tripura
    (AAU, Jorhat, 2017-07) Nandy, Pratul Kumar; Baruah, A.M.
    Ginger (Zingiber officinale Rosc.), under the family Zingiberaceae, is one of the most famous spices all over the world. It is commonly known as Ada (Assamese and Bengali name), originated from South East Asia. Ginger plants are used for thousands of years in Indian health care systems for their biological activities. Ginger is also used as home remedy and is of immense value in treating various gastric ailments like constipation, belching, bloating, gastritis, epigastric discomfort, gastric ulcerations, indigestion, and vomiting. Ginger with spicy, penetrating, pungent, and slightly biting flavor finds extensive use in foods. The present study was carried out to investigate the some major secondary phytochemicals of four different ginger cultivars from Tripura. The moisture content was highest in Gandacherra cultivar (86.167g/100g) and lowest in Satpara cultivar (82.580g/100g). Total phenol content was highest in Belonia cultivar (0.733g/100g) and lowest in Gandacherra cultivar (0.395g/100g).The total flavonoid content was highest in Satpara cultivar (0.379g/100g) and lowest in Gandacherra cultivar (0.103g/100g). The total tannin content was highest in Belonia cultivar (4.237g/100g) and lowest in Satpara cultivar (2.793g/100g).The total soluble sugar content was highest in Gandacherra cultivar (2.760g/100g) and lowest in Dharmanagar cultivar (1.243g/100g). The total crude fat content was highest in Satpara cultivar (8.267g/100g) and lowest in Dharmanagar cultivar (6.967g/100g). The total crude fiber content was highest in Satpara cultivar (6.040g/100g) and lowest in Gandacherra cultivar (4.685g/100g). The antioxidant activity (by DPPH, 2, 2-diphenyl-picrylhydrazide) reveals that the IC50 was highest in Gandacherra cultivar (0.853μg/ml) and lowest in Belonia cultivar (0.809 μg/ml). The total oil content was highest in Dharmanagar cultivar (4.180ml/100g) and lowest in Gandacherra cultivar (3.275ml/100g). The highest acid value was recorded in Belonia cultivar (19.635μg KOH/mg fat) and the lowest acid value was recorded in Gandacherra cultivar (11.220μg KOH/mg fat). The highest iodine value was observed in Belonia cultivar (71.063g I2/100g fat) and the lowest iodine value was observed in Dharmanagar cultivar (64.719g I2/100g fat). The highest saponification value is observed in the Gandacherra and Satpara cultivar (196.350 mg KOH/g fat) and the lowest saponification value was observed in Belonia cultivar (168.300 mg KOH/g fat).
