electrospray ionization mass spectrometry imaging of the crude extract from the peels of Citrus aurantium L
(Rutaceae). Rapid Commun. Mass Spectrom. 29, 1530-1534 (2015). HPTLC of complex phytoconstituents in the peels of Citrus aurantium on silica gel with ethyl acetate - acetic acid - formic acid - water 100:5:5:13. Detection by spraying with vanillin reagent. Images were acquired by desorption electrospray ionization mass spectrometry in the positive ionization mode. The method allowed the identification of 20 compounds.
Planta Medica 82, 09/10, 903-909 (2016). To monitor the sorbent phase purification of a chloroform subfraction of the sponge Myxilla incrustans, TLC of fractions on silica gel with dichloromethane – methanol – formic acid 900:100:1, detection with Dragendorff’s reagent. The four positive fractions were purified by preparative HPLC, yielding three new N-acyl dopamine/dehydrotyrosine glycosides: myxillins A, B and C._x000D_
J. of Chromatogr. A 1415, 155-160 (2015). Presentation of a technique for direct analysis of raw samples by TLC coupled with electrospray ionization mass spectrometry (ESI-MS) instead of conventional MS analysis, which for raw samples commonly requires time-consuming and laborious sample pretreatment and separation using HPLC or GC. The analytes of interest could be extracted, ionized and detected by ESI-MS with much reduced matrix interference because the interfering compounds were retained by the sorbent material of the TLC plate. Demonstration by applying in direct analysis of samples containing common interfering compounds, e.g. salts and detergents. Rapid detection and quantification of target analytes in raw samples showed that the TLC-ESI-MS method was simple, rapid, efficient and could be effectively applied in offline and online separation and detection of different components in raw samples, e.g. plant extracts.
Planta Medica 83(03/04), 351-357 (2017). Acid hydrolysis of five new dammarane-type saponosides extracted from Panax japonicus var. major rhizomes for 5 h in methanol – HCl 1:1 in sealed capillary at 80°C, then TLC on silica gel with n-butanol – acetic acid – water 5:1:4 (upper phase) and with chloroform – methanol – water 16:8:1. After derivatization with aniline phthalic acid reagent, sugar moieties were identified as glucose units by comparison to standards. Note that in the title, by ignorance of the Latin grammar, the authors wrote “Panacis majoris” instead of the nominative “Panax major”. In the names of the compounds, the –ane or –ene ending was often also omitted.
J. Chromatogr. Sci. 54 (4), 609-617 (2016). HPTLC of sulbutiamine (SUL) in the presence of different degradation products after subjecting the drug to stress conditions (according to ICH: neutral, alkaline and acidic hydrolysis, oxidation, photodegradation and dry heat degradation), on silica gel aluminum foil with acetone – methylene chloride – ammonia buffer (pH 8.5±0.2) 14:6:1. Densitometric evaluation at 254 nm. The calibration curve was between 0.4–5.0 µg/zone with good correlation coefficients. The LOD and LOQ were 110 and 330 ng/zone, respectively. Structure elucidation of the resulting degradation products by ESI-MS/MS. The results showed that the drug was completely degraded with 0.1 N NaOH, 1 N HCl and 30 % hydrogen peroxide, while it was partially degraded by 0.1 N HCl, 3 % hydrogen peroxide and UV light. The hRf of SUL was 46 and the zone was completely separated from all obtained degradation products.
Planta Med. 83(07), 661-671 (2017). Structural modifications of 9α- and 9β-hydroxyparthenolide (isolated from Anvillea radiata aerial parts) were performed either by Heck’s reaction (a palladium(II) acetate treatment in presence of triethylamine and iodoaryl in dimethylformamide), or by acylation (here, addition of aroyl chlorides and/or acetic anhydride in dichloromethane and pyridine). TLC for reaction monitoring of the 21 derivatives on silica gel with petroleum ether – ethyl acetate in various proportions (3:2; 1:4; 1:1). Detection under UV or under white light after spraying with 5 % phosphomolybdic acid in ethanol, followed by heating.
