J. Food Comp. Anal. 21, 577-581 (2008). HPTLC of a novel fluorescent compound of nutmeg (Myristica fragrance) on silica gel with hexane – diethyl eter – acetic acid 50:50:1. Detection under UV at 265 nm or by spraying with sulphuric acid 50% followed by heating at 180 °C. The major fluorescent band at hRf 63 was further purified on silica gel using dioxane – acetonitrile – acetic acid 70:30:1. The hRf value of the novel compound was 61. Quantitative determination by absorbance measurement at 376 nm. Linearity was between 1 to 50 µg/spot. The compound was identified as 2-methyl-1,4,4a,8a-tetrahydro-endo-1,4-methanonaphthalene-5,8-dione.
grown in Jamaica. J. Agric. Food Chem. 56, 3664-3670 (2008). HPTLC of curcumin from the rhizomes of Curcuma longa on silica gel with chloroform - ethyl acetate 19:1. Detection by spraying with ammonium molybdate 5 % in aqueous sulphuric acid and examination under UV 254 nm. The hRf value of curcumin was 57.
Food Chem. 113, 640-644 (2009). HPTLC of curcumin (1), demethoxycurcumin (2), and bisdemethoxycurcumin (3) from the rhizomes of Curcuma longa on silica gel with chloroform - methanol 24:1. Quantitative determination by absorbance measurement at 425 nm. The hRf values of (1), (2), and (3) were 66, 48, and 30, respectively. Selectivity regarding matrix was given. Linearity was between 1 and 20 µg/spot for all curcuminoids. The intermediate precision of the method was satisfactory. Recovery was 98.7 % for (1), 96.3 % for (2), and 97.2 % for (3). The limit of detection for the substances was 100 ng/spot.
Chromatographia 65 (3-4), 239-243 (2007). TLC of solasodine in various Solanum species on silica gel with a developing solvent containing an organic acid to form ion pair complexes of solasodine with the acid dye. The resulting colored complex was quantified by absorbance measurement at 461 nm. Linearity was between 79 and 495 ng/spot with a correlation coefficient of 0.995. The method eliminates post derivatization steps and the problem of background interference. Application of the method to determine solasodine content in various herb samples, herb extract and their formulations showed an accuracy of 98.5 ± 2.8 % without matrix interference.
60th Indian Pharmaceutical Congress PA-202 (2008). HPTLC of allyl disulphide (an active ingredient of Allium sativum, garlic) on silica gel with n-hexane. The hRf value was 52. Quantitative determination by absorbance measurement at 298 nm. The linearity range was 200-1200 ng/spot. Several polyherbal formulations containing garlic were analyzed with the proposed method using allyl disulphide as marker.
J. Pharm. Biomed. Anal. 47, 790-794 (2008). HPTLC of the steviolbioside, stevioside and rebaudioside A in Stevia rebaudiana leaves on silica gel with ethyl acetate - ethanol - water 20:5:3. Detection by spraying with acetic anyhdride - sulphuric acid - ethanol 1:1:10 reagent. Quantitative determination by absorbance measurement at 510 nm. Linearity was in the range of 160-960 ng/spot for steviolbioside, 1-6 µg/spot for stevioside and 0.5-3 µg/spot for rebaudioside A with good correlation coefficients (0.998-0.999). The method was used for the assay of steviol glycosides in S. rebaudiana leaves collected from ten different locations.
60th Indian Pharmaceutical Congress PG-263 (2008). HPTLC of rutin in methanolic extracts of fresh leaves of Moringa pterygosperma on silica gel with ethyl acetate - formic acid - glacial acetic acid - water 100:11:11:26. Quantitative determination by absorbance measurement at 254 nm. The method provided good resolution of rutin from other constituents of the plant.
J. Sep. Sci. 32, 3239-3245 (2009). HPTLC of shikonin (1), acetylshikonin (2), and beta-acetoxyisovalerylshikonin (3) in four species of Arnebia on RP-18 with acetonitrile - methanol - 5 % formic acid 20:1:4. Quantitative determination by absorbance measurement at 520 nm. Linearity was in the range of 100-600 ng/zone for (1) and (2) and 100-1800 ng/zone for (3). The limits of detection for (1), (2) and (3) were 18, 15 and 12 ng/zone, respectively, while the limits of quantification were 60, 45 and 40 ng/zone, respectively.
