Planta Medica 82 (15), 1374-1380 (2016). To monitor the subfractionation with methanol on cyclodextrin of a butanol fraction of a methanolic Soxhlet extract of Tamaris Africana shoots, TLC on silica gel with n-butanol – acetic acid – water 12:3:5 and chloroform – methanol – water 70:30:3. Chromatograms were derivatized with Natural Product/PEG reagent and with cerium sulfate sulfuric acid reagent. From the obtained subfractions, flavonoids (three sulfated) and phenolic compounds (ferulic and veratric acid derivatives) could be further isolated.
J. Ethnopharmacol. 195, 10-19 (2017). HPTLC of mesembrine alkaloids (mesembrine, mesembrenone, mesembrinol, mesembrenol, epimesembranol, epimesembrenol) in the South African medicinal plant Sceletium tortuosum on silica gel with dichloromethane – methanol – 10 % ammonia 900:100:1. Quantitative determination by absorbance measurement at 280 nm. The LOD and LOQ were in the range of 18-31 ng/zone and 44-95 ng/zone, respectively.
chromatographic method for simultaneous estimation of the active pharmaceutical ingredients metolazone and spironolactone
J. Planar Chromatogr. 29, 380-387 (2016). HPTLC of metolazone (1) and spironolactone (2) on silica gel with ethyl acetate ‒ chloroform ‒ glacial acetic acid 50:50:1. Quantitative determination by absorbance measurement at 238 nm. The hRF values for (1) and (2) were 51 and 79, respectively. Linearities were between 50 and 300 ng/zone for (1) and 200 and 1200 ng/zone for (2). The intermediate precisions were below 1.3 % (n=6). The LODs and LOQs were 2 and 5 ng/zone for (1) and 5 and 16 ng/zone for (2). Average recoveries were 99.7 % for (1) and 99.7 % for (2). The developed method successfully separated drug substances from degradation products formed under various stress conditions.
J. Liq. Chromatogr. Relat. Technol. 40, 50-57 (2017). HPTLC of six nucleobases, guanosine (1), guanine (2), cytosine (3), adenine (4), uracil (5), and thymine (6) in sea buckthorn leaves on silica gel with dichloromethane – methanol – formic acid 160:45:16. Detection at UV 254 nm. The hRF values for (1-6) were 17, 23, 32, 38, 64 and 73, respectively. The bands were eluted using a TLC–MS interface and subjected to electrospray ionization-mass spectrometry (ESI-MS)._x000D_
J. Ethnopharmacol. 197, 184-194 (2017). HPTLC of arjunetin in Terminalia arjuna on silica gel with ethyl acetate – toluene – formic acid – acetic acid 12:6:1:2. Detection by spraying with anisaldehyde sulfuric acid reagent. The hRF value for arjunetin was 25.
J. Planar Chromatogr. 30, 126-130 (2017). TLC–direct bioautography of various hop varieties (Humulus lupulus L.) on silica gel with dichloromethane – acetonitrile 4:1 for ethanolic extracts and acetonitrile – methanol – dichloromethane 5:2:3 for aqueous extracts. The TLC plate was immersed in the bacterial suspension using the strains B. subtilis (ATCC 6633) and E. coli (ATCC 25922) and incubated under typical conditions.
J. Chromatogr. Sci. 54 (9), 1661-1669 (2016). Development of two sensitive and accurate stability-indicating chromatographic methods for the determination of rafoxanide (RFX): 1) by TLC on silica gel with chloroform – ethyl acetate – toluene – ammonia 50:40:3:1, determination by densitometry at 280 nm; 2) by UPLC. Identification of the degradation products by mass spectrometry and IR spectroscopy. Both proposed methods proved to be accurate, robust, specific and suitable for application as stability-indicating methods for routine analysis of RFX in quality control laboratories.
Phytochem. Anal. 29, 5-15 (2018). TLC fingerprint of Ipomoea aquatica on silica gel with methanol – water from 1:1 to 9:1 (1) or methanol with 0.05 % trifluoroacetic acid – water with 0.05 % trifluoroacetic acid 1:1 (2). Detection by spraying with anisaldehyde sulfuric acid reagent. Detection under UV 254 nm, 366 nm, and for (2), white light (yellow bands at hRF 19 and 25). The post chromatographic visualization possibilities indicate the potential of TLC in qualitative fingerprint analysis.
