J. Planar Chromatogr. 27, 140-144 (2014). HPTLC of andrographolide (1), neoandrographolide (2) and deoxyandrographiside (3) in the aerial parts of Andrographis paniculata on silica gel with dichloromethane - toluene - ethanol 13:5:3. Detection by dipping into p-anisaldehyde–sulfuric acid reagent, followed by heating at 110 ºC for 6 min. For quantification, image analysis with an office scanner at 200 dpi and densitometric measurement in absorbance mode at 540 nm. The hRF values for (1) to (3) were 61, 35 and 16, respectively. Linearity was in the range of 3-24 μg/zone for (1) and 1-8 μg/zone for (2) and (3). The intermediate/interday/intra-day precisions were below 3 % (n=3). The LOD and LOQ were 510 and 1700 ng/zone for (1), 140 and 480 ng/zone for (2) and 6 and 190 ng/zone for (3), respectively. Recovery was between 96.1 and 104.3 % for (1) to (3). Comparable results were obtained with the TLC-image analysis method, TLC-densitomety and HPLC.
J. Planar Chromatogr. 28, 458-465 (2015). TLC of protodioscin in Trigonella foenum-graecum on silica gel with chloroform – methanol – glacial acetic acid 13:6:1. Detection by dipping into a solution of p-dimethyl aminobenzaldehyde in methanolic hydrochloric acid for 2 s, followed by heating at 110 °C for 3 min. Quantitative determination by absorbance measurement at 515 nm. The hRF value for protodioscin was 31. Linearity was in the range of 400-1400 ng/zone. LOD and LOQ were 100 and 400 ng/zone. The intermediate precision was below 5.1 % (n=3). Average recovery was 101 %.
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.
Planta Med. 83(09), 797-804 (2017). For the analysis of their sugar moieties, five new triterpene saponins (ilexpusons B, D, E, F, G), isolated from a methanolic extract of Ilex pubescens roots, were hydrolyzed at 90 °C in water containing HCl and dioxane. TLC of the dried aqueous phases on silica gel with chloroform – methanol – water 8:5:1. Detection by spraying with aniline – diphenylamine reagent (2 mL aniline, 2 g diphenylamine, 10 mL phosphoric acid 85%, in 100 mL acetone) and heating for 2-5 min at 85 °C. By comparison with standards, the sugar moiety was identified (before confirmation by GC) as glucose (hRF 49) in ilexpuson B, as xylose (hRF 81) in ilexpusons D and E, and as glucuronic acid (hRF 44) in ilexpusons F and G.
Synthesis of partially benzylated thioglycoside derivatives. Acta Chimica 113, 415-422 (1983). TLC of phenyl-2,3-di-O-benzyl-4,6-O-benzylidene-1-thio-beta-D-gluco- and -galactopyranoside; phenyl-2,3,6,2',3'-penta-O-benzyl-4',6'-O-benzylidene-1-thio-beta-cellobioside on silica with benzene -methanol 1:1. Detection with 50 % sulfuric acid.
Phytochemistry 24, 1561-1565 (1985). TLC of steroidal saponins on silica with chloroform - methanol - propanol - water 70:20:6:3, chloroform - methanol - water1 4:6:1 or butanol - ethanol - water 5:1:4 (upper layer). Also TLC of methylated glucoseson silica with butanol - ethanol - NH3 - water 40:10:1:49 (upper layer).
Phytochemistry 25, 2501-2503 (1986). TLC of oleanolic acid glycosides on silica with chloroform - methanol - water 6:4:1. Detection with Godins reagent. After hydrolysis of the saponins, the aglycones are identified by TLC on silica with isopropylether -acetone 3:1 and the sugars by TLC on silica with ethyl acetate - methanol - formic acid water 13:3:4:3. Detection with naphthoresorcinol.
J. Chinese Herb Med. 18, 405-408 (1987) (Zhong Caoyao). TLC of 3H-Rg1 on silica with chloroform - methanol - water 65:35:10. Detection by spraying with 5% sulfuric acid - methanol and heating at 100-110 °C for 5 min. Quantification by scintillation counting after elution.
