59th Indian Pharmaceutical congress C-327, 303, (2007). HPTLC of 3-beta-23-24 -trihydroxy-olean-12-en-28-oic acid in Convolvulus pluricaulus on silica gel with n-hexane - ethyl acetate 7:4. Quantitative determination by densitometry at 226. The limit of detection and quantification was14.2 and 50 ng/zone, respectively. Recovery was 94.5 % - 97.2 %. The method was applied for analysis of herbal syrup and tablets.
59th Indian Pharmaceutical congress F-218, 442, (2007). HPTLC of alcoholic extracts of Euphorbia hitra on silica gel with toluene - ethyl acetate - glacial acetic acid 12:8:1. Densitometry at 377 nm. The hRf value of quercetin was 28. The calibration range was 10-60 ng/zone. All the flavanoid constituents such as quercetin were well separated. The plant material collected from different locations showed almost similar fingerprint profile.
CBS 100, 10-12 (2008). HPTLC of beta ecdysone in Pfaffia glomerata extract on silica gel over 50 mm with the lower phase of chloroform - methanol - water 7:5:2 after chamber saturation for 15 min. Detection by dipping in anisaldehyde reagent (0.5 mL anisaldehyde, 10 mL acetic acid, 5 mL sulfuric aicd, and 85 mL methanol) followed by heating at 120 °C for 20 min. Quantitative determination by absorbance measurement at 432 nm. Polynomial calibration in the range of 0.04 to 0.2 µg/band (sdv 1.6 %). The evaluated extracts contained 0.8 to 1.2 % of beta ecdysone.
J. Sep. Sci. 31, 237-241 (2008). HPTLC of chlorogenic acid in green coffee beans on silica gel with ethyl acetate - dichloromethane - formic acid - acetic acid - water 100:25:10:10:11. Quantitative determination by absorbance measurement at 330 nm. The hRf value was 27 and selectivity regarding matrix was given. Linearity was between 550 and 1750 ng/spot. The limits of detection and quantification were 80 and 250 ng, respectively. Recovery was 97.1 %. The intermediate/interday/intra-day precision was between 1.06 % and 1.35 % (n=6). The data showed no statistically significant differences for HPTLC and HPLC methods.
Part I: Graft TLC of selected coumarins. J. Planar Chromatogr. 21, 237-241 (2008). HPTLC of coumarins (present in extracts of Archangelica officinalis, Pastinaca sativa and Heracleum sphondylium fruits) on cyano phase with acetonitrile - water 3:7 (triple development) in the first dimension, and on silica gel with ethyl acetate - n-heptane 7:13 (triple development) in the second dimension. Good selectivity differences were also obtained on silica gel with ethyl acetate - n-heptane 7:13 (triple development) in the first dimension and on RP-18 phase with methanol - water 11:9 (triple development) in the second dimension. Detection and quantitative determination by fluorescence measurement at 366 nm.
Rev. Fac. Agron. 21, 155-160 (2004). HPTLC of betaxantin and betacyanin in the roots of Beta vulgaris on cellulose in two one-dimensional developments with 1) isopropanol – ethanol – water – acetic acid 6:7:6:1 and 2) isopropanol – ethanol – water – acetic acid 11:4:4:1. Qualitative identification under UV light. Betaxantin and betacyanin showed maximum absorbances at 537 and 465 nm, respectively. The hRf values of betaxantin and betacyanin were 22 and 34, respectively.
Chinese J. Modern Appl. Pharm. 25 (1), 66-69 (2008). TLC of Qufu Zhuanggu capsule extracts on silica gel with 1) n-hexane - ethyl acetate 4:1; 2) benzene - ethyl acetate 9:1; 3) chloroform - methanol 19:1; 4) cyclohexane - ethyl acetate 5:2; 5) n-hexane - acetone 3:1. Detection 1) under UV 365 nm; 2) by spraying with 10 % sulfuric acid in ethanol and heating at 105 ºC until the spot were visualized; 3) by treatment with ammonia vapors for 10 min; 4) by spraying with 20 % HClO4 in ethanol. Identification by comparison of the chromatograms with those of the standard psoralen.
