Helv. Chim. Acta 74, 791-799 (1991). TLC of phenolic tetracyclic compounds on silica with chloroform - methanol 95:5 and HPTLC on RP-18 with methanol - water 8:2 or on diol with ethyl acetate - petrol ether 1:1. Detection by UV 254/366 nm or with Godin reagent. Also bioautography with spores of the plant pathogenic fungus cladosporium cucumerinum. HPTLC on RP-8 and on diol allowed the separation of closely related compounds and transposition to prep. HPLC.

Most phloroglucinols gave red spots after spraying with Godin’s reagent. determination of the antibacterial activity against Bacillus subtilis by TLC bioautography on silica.

J. Liq. Chrom. & Rel. Technol. 20, 1887-1901 (1997). TLC of 27 coumarins (simple coumarins (umbelliferone, herniarin, scopoletin, ostruthin, methyl umbelliferone, osthol), linear (5-methoxypsoralen, isopimpinellin, imperatorin, peucedanin, phellopterin, oxypeucedanin, isoimperatorin, psoralen, ostruthol, xanthotoxin)and angular (angelicin, athamantin, pimpinellin, sphondin, isobergapten) furanocoumarins, linear (xanthalin, peuarenarine, peuarenine) and angular (cis-epoxypteryxin, anomalin, pteryxin) pyranocoumarins) on silica gel. Using the "PRISMA" optimization process, dioxan, ethanol, and diethyl ether in n- hexane 56:63:97:784. UV spectra were obtained using a dual wavelength scanner at wavelengths between 200 nm and 370 nm.

Planta med. 65, 94-96 (1999). Preparative TLC of b-sitosterol and 2 new sesquiterpene lactones, the pyrazoline derivatives of carpelipine A and B, on silica gel with petroleum ether - dichloromethane - ethyl acetate 20:3:1 for carpelipine A and petroleum ether - ethyl acetate 6:1; 1 or 2 developments for carpelipine B.

Planta med. 68, 146-151 (2002). Analytical and preparative TLC of trifolirhizin, quercetin, euchretin K, L, M, and N on silica gel using i. a. chloroform - methanol - 29 % ammonia 100:10:1, n-hexane - chloroform 20:1 and 30:1, chloroform - methanol 10:1, 20:1 and 30:1 as well as n-hexane - acetone 4:1, 7:1, 10:1 and 60:1. Detection by spraying with Dragendorff's reagent or 50 % sulfuric acid followed by heating on a plate heater.

International Journal of ChemTech Research 1(4), 1079-1086 (2009). TLC of wedelolactone, quercetin, and jatamansone in a polyherbal formulation. The formulation (oil) was extracted with methanol, the supernatant was concentrated under vacuum and used for chromatographic analysis. TLC on silica gel with toluene - acetone - formic acid 11:6:1 for wedelolactone, toluene - ethyl acetate - methanol 44:50:6 for quercetin and petroleum ether - acetone 3:1 for jatamansone. The hRf value of jatamansone was 34, of wedelolactone 56, and of quercetin 47. Densitometric evaluation at 254 nm, 285 nm and 366 nm for quercetin, jatamansone, and wedelolactone respecticely. The method was linear in the range of 500-2500 ng/band for wedelolactone, 3000-8000 ng/band for quercetin and 2000-6000 ng/band for jatamansone. The polyherbal oil formulation contained 1.62 %, 0.24 % and 0.11 % of wedelolactone, quercetin, and jatamansone respectively.

J. Planar Chromatogr. 28, 54-60 (2015). HPTLC of bergenin in the aerial parts of Flueggea virosa on silica gel with dichloromethane – methanol 17:3. Quantitative determination by absorbance measurement at 220 nm. The hRF value of bergenin was 29. Linearity was between 100 and 800 ng/zone. The intermediate intra-day and inter-day precisions were below 2 % (n=6). The LOD and LOQ for bergenin were 18 and 53 ng/zone, respectively. Recoveries were in the range of 99-100 %.
