استخلاص و تقدير مركبات الكركمين باستعمال ثلاثة متغيرات (مذيب و وقت و درجة الحرارة)‎ من رايزومات الكركم

الملخص EN

The study aimed to investigate the effect of different times as follows 0.5, 1.00, 2.00 and 3.00 hrs, type of solvent (acetone, methanol and ethanol) and temperature (~ 25 and 50)ºc on curcumin percentage yield from turmeric rhizomes.

The results showed significant differences (p≤ 0.05) in all variables.

The curcumin content which were determined spectrophotometrically ranged between (0.55-2.90) %.

The maximum yield was obtained when temperature, time and solvent were 50ºC, 3 hrs and acetone, respectively.
