      Occurrence and activity of natural antioxidants in herbal spirits
      C. IMARK, M. KNEUBUEHL, S. BODMER* (*Biodyn GmbH, Industriestrasse 31, CH-8305 Dietlikon, Switzerland, bodmer@biodyn.ch)

      Innovative Food Science and Emerging Technologies 1, 239-243 (2001). HPTLC of commercial herbal spirits (alcoholic or hydroalcoholic solutions of volatile substances with flavoring or medicinal properties) and one red wine on silica gel with toluene – ethyl formate – formic acid 79:20:1. Antioxidative components were detected by dipping for 30 s in a soybean oil solution (3 % in n-hexane, previously treated with active carbon). Quantitative determination in UV light at 254 nm after different times of UV-exposure (30 min – 20 h). The antioxidant activity could be evaluated from the fluorescence-persisting time of the respective spots and was correlated with linoleic acid oxidation and DPPH-titration methods. Although the nature of the active herbal antioxidants remains to be established, phenolic compounds seem to be key candidates.

HPTLC of terpenelactones (total bilobalide, gingkolide A, and gingkolide B) on prewashed and sodium acetate preimpregnated silica gel with toluene - ethyl acetate - acetone - methanol 50:25:25:3 or ethyl acetate - hexane 9:1; also HPTLC of flavonol glycosides (quercetin, kaempferol, isorhamnetin as standards) on prewashed and preimpregnated silica gel with chloroform - acetone - formic acid - acetic acid 50:11:6:6. Plates were developed in solvent equilibrated, vapor saturated twin-trough chambers at 30°C. Densitometry in absorbance mode at 370 nm (for aglycones) and at 290 nm following a 1 s immersion in acetic anhydride and heating at different temperatures for varying lengths of time (for terpenelactones). Good relationship (95%) was determined between HPTLC and HPLC for determination of total flavonol glycosides. The HPTLC flavonol aglycone method also performed well in terms of accuracy and consecutive plate repeatability.
