J. Planar Chromatogr. 26, 475-479 (2013). HPTLC of beta-amyrin in the aerial parts of Maytenus obscura and Maytenus parviflora on silica gel with hexane - ethyl acetate 3:1. Detection by spraying with p-anisaldehyde, followed by heating at 105 ºC for 10 min. Quantification by absorbance measurement at 550 nm. The hRf of beta-amyrin was 38. Linearity was in the range of 10-100 ng/zone. LOD and LOQ were 9 and 27 ng/zone. Recovery was in the range of 99.3-99.7 %. Intermediate/interday/intra-day precision was below 2 % (n=6).
of Betula utilis D
Don using a validated high-performance thin-layer chromatographic method. J. Planar Chromatogr. 31, 220-229 (2018). Quantitative TLC of betulin (1), lupeol (2), oleanolic acid (3), and betulinic acid (4) in the bark, leaves, and roots of Betula utilis on silica gel with n-hexane ‒ ethyl acetate 4:1 for (1) to (3), and with toluene – ethyl acetate 7:3 for (4). (1) to (3) were detected by dipping into ceric ammonium sulfate reagent, followed by heating at 105–110 °C for 5 min. Compound (4) was detected by spraying with Liebermann‒Burchard reagent, followed by heating at 105–110 °C for 5 min. Quantitative determination by absorbance measurement at 500 nm for (1) to (3) and 550 nm for (4). The hRf values for (1) to (4) were 59, 71, 48 and 71, respectively. Linearity was in the range of 2.5-10 μg/zone for (1) to (4). The intermediate precision was below 4 %. The LOD and LOQ were 175 and 532 ng/zone for (1), 166 and 504 ng/zone for (2), 396 and 1201 ng/zone for (3) and 109 and 330 ng/zone for (4), respectively. Average recoveries for (1) to (4) were 98.9, 99.3, 99.3 and 99.2 %, respectively.
Journal of Natural Products 50, 253- 255 (1987). TLC on silica with chloroform - methanol 85:15. Detection by spraying with vanillin-sulfuric acid reagent and heating for 10 min. at 100 °C. An acidic hydrolysis fraction of feruginidin and ferugin was identified as p-hydroxybenzoic acid.
