“…Peaks 2, 10, 11, 12, 17, 20 and 21 were characterized as anthronesand. Peaks 4 and 13 were characterized as an anthraquinone . The preliminary identification for anthrones could be confirmed by the characteristic UV maximum absorption at 269–270, 297–303, 355–365 nm.…”

An effective and comprehensive method was developed for the simultaneous analysis of compounds in the powder of Aloe arborescens Mill by liquid chromatography with ion trap time‐of‐flight mass spectrometry and high‐performance liquid chromatography with diode array detection. Qualitative analysis of all the compounds presented in Aloe arborescens Mill was performed by liquid chromatography with ion trap time‐of‐flight mass spectrometry. A total of 28 components from Aloe arborescens Mill were identified, including chromones, phenyl pyrones, anthrones and anthraquinones. The quantitative analysis of multi‐components by a single‐marker method was developed and validated for the simultaneous determination of aloenin, 2′‐α‐rhamnopyranosylisovitexin, aloinA, and aloinB in Aloe arborescens Mill leaves using high‐performance liquid chromatography. We can than calculate the contents of the other constituents with the relative correction factors correspondingly. In comparison with the results obtained using the external standard method, the quantitative analysis of multi‐components by the single‐marker method demonstrates no significant difference. This is the first simultaneous characterization and quantitative determination of multiple compounds in Aloe arborescens Mill. It can be applied to standardize the quality of Aloe arborescens Mill as well as the future design of nutraceutical and cosmetic preparations.

Februar 1977) Wie die Thermofraktographie (TFG) zeigt, sind zahlreiche pflanzliche Anthrachinonderivate unzersetzt fluchtig. Sie lassen sich somit direkt auf die DC-Schicht transferieren. Die monomeren Anthrachinon-0-glykoside spalten sich in definierter Weise. Die nichtfliichtigen Dimerisierungsprodukte und die Glykosylderivate konnen mittels einer sauren oder basischen Oxidation mit Wasserstoffperoxid gespalten werden. Auf diesem Wege lassen sich auch die Anthron-und Anthranolderivate in die entsprechenden Anthrachinone iiberfuhren. Es wird gezeigt, d& dieses Verfahren auch direkt auf pflanzliche Drogen iibertragbar ist. Die Thermofraktogramme von nicht-oxidierten und oxidierten Drogen von Frangulae und Rhamni pursh. Cort., Rhei Rad., Sennae Fol. und Fruct. sowie von Aloe werden erkutert. Thermofractography of Anthraquinone Derivatives and Related Natural DrugsAs thermofractography shows, numerous vegetable anthraquinone derivatives are volatile without being decomposed and can be transferred directly onto the TLC layer. The monomericanthraaverlag Chcmie, GmbH, Weinheim 1978 f78Thermo fraktograp hie 59 quinone 0-glycosides are split in a definite manner. The nonvolatile dimerization products and the glycosyl derivatives can be split by acidic or basic oxidation with hydrogen peroxide. In this way, anthrone and anthranol derivatives can be converted into anthraquinones It is shown that this procedure can be applied directly to vegetable drugs. The thermofractograms of nonoxidized and oxidized drugs of Frangula bark, Cascara, Rhubarb, Senna leaf and Tinnevelly Senna pods and Aloe are interpreted.
