Chromatographia 66 (9-10), 801-804 (2007). HPTLC of withaferin A and withanolide A in Withania somnifera methanolic extract from different plant parts (leaf, root, stem and fruit) and of two morphotypes, on silica gel with toluene - ethyl acetate - formic acid 5:5:1. Quantification by densitometry in absorption mode at 530 nm. Linearity was between 200 and 3200 ng for both withaferin A and withanolide A. The average recovery of withaferin A and withanolide A was 96.0 and 96.7 %.
59th Indian Pharmaceutical Congress F-65, 405, (2007). HPTLC of nebivolol and hydrochlorothiazide in on silica gel with n-butyl-acetate - formic acid - chloroform 7:1:2. Densitometry at 273 nm. The hRf value of nebivolol was 21 and of hydrochlorothiazide 46. Linearity was between 200 and 600 ng/zone for nebivolol and between 500 and 1000 ng/zone for hydrochlorothiazide. The limit of quantification was 60 ng and 40 ng/zone for nebivolol and hydrochlorothiazide, respectively. Recovery was 102 - 105 % for both compounds.
Chromatographia 67 (3-4), 269-274 (2008). Presentation of a quantitative method using silica gel HPTLC plates, automated bandwise sample application, and automated visible mode densitomety for the determination of 24beta-ethylcholesta-5,22E,25-triene-3beta-ol (ECTO) in the aerial part of Clerodendrum phlomidis, which was used as a chemical marker for the standardization of C. phlomidis plant extracts. HPTLC on silica gel with chloroform - methanol 197:3. Detection by derivatization with anisaldehyde reagent. Quantitative determination by absorbance measurement at 650 nm. Linearity was between 150 and 400 ng/band with good correlation (r2 = 0.996).
J. Chromatogr. Sci. 46 (4), 320-324 (2008). HPTLC of jasmonic acid (extracted from Lasiodiplodia theobromae with ethyl acetate) on silica gel with isopropanol - ammonia - water 10:1:1. Quantification by densitometry at 295 nm in absorbance mode. The limit of detection and quantification was 1 µg and 80 µg, respectively. The method is useful for high sample throughput, e.g. for routine analysis of jasmonic acid in perfumery industries.
J. of Pharm. Biomed. Anal. 44 (3), 812-817 (2007). HPTLC of extracts of Notopterygium incisum Ting ex H.T. Chang (or Notopterygium forbesii Boiss) root and rhizome, and marker compounds isoimperatorin, notopterol and bergapten. The authentication of rhizoma et radix Notopterygii was achieved by comparing the colors and Rf values of the bands in TLC fingerprints with those of the marker compounds. The HPLC fingerprints of 16 batches of herbal samples from different regions of China showed similar chromatographic patterns. Five peaks were selected as characteristic peaks, and three of these were identified by using LC-MS-MS techniques.
J. Chromatogr. Sci. 46 (10), 907-911 (2008). Examination of M(DEDTC)2 (M = Cu, Co, or Ni) and M(PyDTC)2 (M = Cu or Co) complexes prepared by reactions of sodium diethyldithiocarbamate (NaDEDTC) and ammonium pyrrolidinedithiocarbamate (NH4PyDTC) with metal (II) nitrates. Qualitative analysis and separation using TLC systems in the literature. Reexamination and discussion of the already known separation behaviour of the mentioned metal cations and their complexes in the context of relation to the crystal field theory (CFT) and TLC. Based on the chromatographic data it was found that CFT is closely related to the TLC separation of these metal cations and their complexes. This study is useful in understanding the linkage between the CFT of coordination chemistry and the chromatographic parameters, e.g., hRf value and theoretical plate numbers of the complexes.
J. Liq. Chromatogr. Relat. Technol. 31, 1881-1891 (2008). HPTLC of various neutral lipid classes on silica gel (prewashed with dichloromethane - methanol 1:1) with petroleum ether - diethyl ether - acetic acid 80:20:1 in a twin trough chamber saturated for 20 min. Detection by spraying with 5 % ethanolic phosphomolybdic acid solution and heating for 10 min at 110 °C. Quantitative determination by absorbance measurement at 610 nm.
60th Indian Pharmaceutical Congress PA-49, (2008). HPTLC of alfuzosin hydrochloride on silica gel with toluene - methanol - triethyl amine 15:5:1. Densitometric evaluation at 245 nm. Linearity was in the range of 5-400 ng/spot. The method was stability indicating (acid, alkali, oxidation, dry and wet heat and photodegradation). The compound was stable to oxidation and alkaline degradation. The hRf value of the main zone was 63, and of additional zones 10 and 33. The method could effectively separate the main drug from the degradation products.
