Abstract:
An experiment on extraction of essential oil and curcumin content was carried out at chemistry lab of D.A.V. College, Kanpur. Turmeric samples were collected from A.N.D. University of Agriculture and Technology Kumarganj, Ayodhya (U.P.) and some biochemical parameters viz. Moisture content, Total mineral content, Carbohydrate content, Crude Fiber content, Curcumin content, Oleoresin content and Essential oil content are studies in different varieties (N.D.H.-1, NDH-2, NDH-3, NDH-98 and Prabha) of turmeric (curcuma longa). Moisture content ranged from 74.98% to 85.03% and maximum moisture was found in NDH-1 (85.03%). Total mineral content ranged from 7.01±0.34 to12±0.34% and maximum total mineral content was found in NDH-1 (12±0.34%). Crude fiber content varied with variety to variety. It ranged from 4.64 to 5.65%. Maximum Crude Fiber (%) in fresh Rhizome was found in NDH-2 (5.65%) followed by NDH-98 (5.6%), NDH-3 (4.75%), NDH-1 (4.65%) and the lowest crude fiber content was found in Prabha (4.64%). Carbohydrate content ranged from 61.50 to 70.40% and maximum Carbohydrate was found in NDH-2 (70.40%).curcumin content varied from (2.22%) to (8.44%), maximum curcumin content was recorded in NDH-2 (8.442%).Oleoresin content ranges from 5.7%. to 21.9% and maximum content was found in NDH-2 (21.9%). Essential oil content ranged from 1.63 to 3.91%. And maximum essential oil content was found in Prabha (3.1%). The results obtained from the analysis of fresh turmeric rhizome indicated that maximum moisture was found in NDH-1 (85.03%). maximum total mineral content was found in NDH-1 (12±0.34%), Maximum Crude Fiber (%) in was found in NDH-2 (5.65%), maximum Carbohydrate in NDH-2 (70.40%), maximum curcumin content in NDH-2 (8.442%), maximum oleoresin content was found in NDH-2 (21.9%)while highest essential oil content in Prabha (3.91%) among all five varieties.
