IPC 56th 2004, Abstract No. G-18. Curculigo Orchioides (Amary llidaceae) is used in various ayurvedic formulations. The rhizomes contain about 5.78 % total phenolis, gallic acid being the major component of the alcoholic extracts. HPTLC of gallic acid on silica gel with toluene - ethyl acetate - glacial acetic acid 25:15:1. The Rf valueof gallic acid was 0.19, the linearity range of 150-750 ng/spot. Rhizomes were found to contain 2.54 % gallic acid, formulations contained 5.13 % gallic acid, recovery was 99.5 %.
Part I. J. Chromatogr. A 1007 (1-2), 145-155 (2003). A quantitative structure-activity relationship analysis of H1-antihistamine activity and chromatographic data of 2-[2-(phenylamino)thiazol-4-yl]ethanamine; 2-(2-benzyl-4-thiazolyl)ethanamine; 2-(2-benzhydrylthiazol-4-yl)ethylamine derivative; 2-(1-piperazinyl- and 2-(hexahydro-1H-1,4-diazepin-1-yl)benzothiazole derivatives were collected. Silica gel RP2, impregnated with solutions of selected amino acid mixtures (-Asp, -Asn, -Thr and -Lys), were used in two developing solvents as hH1R antagonistic interaction models. Using regression analysis, the relationships between chromatographic and biological activity data were found. The correlations obtained in regression analysis for the examined thiazole and benzothiazole derivatives with H1-antihistamine activity [pA2(H1)] represent their interaction with all the proposed biochromatographic models (S1–S7). Some of the calculated equations can be applied to predict the pharmacological activity of new drug candidates. The best multivariate relationships useful in predicting the pharmacological activity of thiazole and benzothiazole derivatives were obtained on RP2 phase with acetonitrile - methanol - buffer 2:2:1. The log P values of particular compounds are extremely important for this kind of activity.
J. Chinese Trad. Patent Med. (Zhongchengyao) 27 (3), 275-278 (2005). TLC of the extracts on silica gel with 1) chloroform - ethyl acetate - methanol - water 15:40:22:10; 2) n-butanol - ammonia - ethanol 5:2:1; 3) the lower phase of chloroform - ethyl acetate - methanol - water 8:8:3:2. Detection 1) by spraying with 10 % H2SO4 in ethanol followed by heating at 105 ºC until the spots appear; 2) by spraying with 5 % potassium iodobismuthate solution. Identification by fingerprint technique. Quantification of ginsenoside Rb1 by HPLC.
