      Structure–retardation factor relationship of natural amino acids in two different mobile phases of RP-TLC
      S. YOUSEFINEJAD*, F. HONARASA, S. AKBARI, M. NEKOEINIA (*Research Center for Health Sciences, Department of Occupational Health Engineering, Institute of Health, School of Health, Shiraz University of Medical Sciences, Shiraz 71645, Iran,

      J. Liq. Chromatogr. Relat. Technol. 43, 580-588 (2020). Retardation factor (hRF) of 42 amino acids in two different eluents (acetonitrile - sodium azide and 1,2 dioxane-sodium azide solutions) were predicted by different quantitative structure-retention relationship (QSRR) methods. The method analyzed the effect of sum of geometrical distances between N and O in separation of amino acids in RP-TLC.

      Indian Drugs 47(2), 71-74 (2010). HPTLC of irbesartan and hydrochlorothiazide on silica gel with acetone - chloroform - ethyl acetate - methanol 6:6:6:1. The plates were preconditioned for 10 min in a saturated chamber prior to development. The hRf value of irbesartan was 27 and of hydrochlorothiazide 37. The linearity was 1500-9000 ng/band and 125-750 ng/band for irbesartan and hydrochlorothiazide respectively. The average recovery for both drugs was 99.4-99.5 %.
