Part II: Remijia ferruginea. Rev. Bras. Farmacogn. 27, 153-157 (2017). HPTLC fingerprint of Remijia ferruginea on silica gel with ethyl acetate – toluene – formic acid – water 12:4:4:3. Detection by spraying with natural product reagent, followed by PEG reagent. The hRF values for rutin, chlorogenic acid and cinchonine were 50, 60 and 65, respectively.
Planta Med. 83(03/04), 334-340 (2017). Preparative layer chromatography on silica gel was used to isolate, from flash column subfractions of ethyl acetate extracts of Lepisanthes senegalensis stem or roots: a) with chloroform – ethyl acetate 3:37 an acetyl-caffeoylbutelin from stem; b) with hexane – ethyl acetate 4:1 two coumaroyl-22-hydroxy-hopanes from root; c) with dichloromethane – ethyl acetate 19:1 a caffeoyl-lupeol from root.
J. Chromatogr. A 1526, 137-150 (2017). HPTLC of physalins from crude extracts of Chinese lantern (Physalis alkekengi L.) on silica gel with ethyl acetate – toluene – formic acid 35:15:1. Densitometric screening of physalins in absorption and in fluorescence mode after post-chromatographic derivatization with sulfuric acid reagent. Identification of the physalin L standard and its impurity, 2,3,25,27-tetrahydrophysalin A. Applying two successive plate pre-developments with methanol – formic acid 9:1 and methanol to avoid strong ion suppression caused by the developing solvent additive (formic acid), and to improve the sensitivity of HPTLC-MS/MS method combined with a slightly modified developing solvent ethyl acetate – toluene – formic acid 30:20:1. Non-targeted characterization of physalins from the same chromatographic zone and determination of physalin types by simultaneous hyphenation of HPTLC with a triple quadrupole and an ion trap mass analyzer. Demonstration of the performance of the HPTLC-densitometric and HPTLC–MS/MS methods for the analysis of physalins from aqueous reflux extracts. Observation of variations in physalin profiles and abundances in different parts of P. alkekengi harvested at different stages of maturity, showed that the husks are the most suitable plant part for P. alkekengi quality control.
characterization of physalin L standard and its impurity
J. Planar Chromatogr. 30, 429-439 (2017). HPTLC of physalin L in orange husks of Physalis alkekengi L. var. franchetii on silica gel with ethyl acetate – n-hexane 3:2. Detection by dipping into 2.5 % (v/v) sulfuric acid in ethanol. Qualitative determination under UV 366 nm. The hRF values for physalin L and its impurity were 61 and 51, respectively, as determined by HPTLC-MS.
Rev. Bras. Farmacogn. 28/1, 92-101 (2018). HPTLC fingerprint of Eugenia uniflora on silica gel with ethyl acetate – formic acid – water 18:1:1. Detection by spraying with natural products reagent followed by PEG reagent. Qualitative identification under UV 365 nm. The hRf values of gallic acid, myricetrin and ellagic acid were 71, 34 and 38, respectively.
and its isolation from Asparagus racemosus Willd
J. Planar Chromatogr. 31, 197-201 (2018). HPTLC of shatavarin IV in the roots of Asparagus racemosus on silica gel with ethyl acetate – methanol – water 15:3:2. Detection by spraying with anisaldehyde sulfuric acid reagent, followed by heating at 105 ºC for 5 min. Quantitative determination by absorbance measurement at 425 nm. The hRf value for shatavarin IV was 43. Linearity was in the range of 600-1800 ng/zone. The intermediate precision was below 2 % (n=3). The LOD and LOQ were 14 and 44 ng, respectively. Average recovery was 96.2 %.
Pharmacogn. Mag. 14, 45-51 (2018). HPTLC of stigmasterol in Monochoria vaginalis and Monochoria hastata on silica gel with chloroform – methanol 4:1. Detection by spraying with anisaldehyde-sulfuric acid reagent, followed by heating at 105 °C for 5 min. Quantitative determination by absorbance measurement at 540 nm. The hRF value for stigmasterol was 30. Linearity was between 1000 and 5000 ng/zone. LOD and LOQ were 80 and 200 ng/zone. The intermediate precision was <3 % (n=3). Average recovery was 99.8 %.
