Judul: Validation method for determination of apigenin in extract celery with high performance liquid chromatography
Abstrak: Apigenin is an active substance derived from celery (Apium graveolens) and widely used for the treatment of gout. Determination method of apigenin which have been validated was introduced by Frankee et al. J Food Compos Anal 17: 1-35 (2005). Apigenin analysis was done by high performance liquid chromatography (HPLC). To make sure that HPLC analysis method can be used for the intended purpose then the method was validated. Parameters determined on method validation were linearity, limit of detection, limit of quantification, precision, and accuracy. All parameters were in accordance with the acceptance criteria of Association of Official Analytical Chemist. The linearity in the concentration of 3,8; 5,7; and 7,6 mg/l had correlation coefficent of 0,9900–0,9998. limit of detection in this method was 2,7222 mg/l and limit of quantification was 8,2500 mg/l. Interday precision in five restating showed good precision with relative standard deviation of 3,85%. Accuracy was determined by standard addition method with recovery percentage of 95,00–118,77%. Average concentration of apigenin is 0,0052% (w/w).
