- Antioxidants in clove
- Antioxidants in clove. Kramer, R. E. (Sch. Adv. Technol. Lab., US Army Natick Res. Dev. Cent., Natick, MA 01760-5020, USA). JAOCS, J. Am. Oil Chem. Soc., 62(1), 111-13 (English) 1985. CODEN: JJASDH. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) With the use of TLC, UV, IR, mass spectrometry (MS), and HPLC, gallic acid [149-91-7] and eugenol [97-53-0] were identified as the 2 major antioxidants in clove. The amts. of gallic acid and eugenol were 1.26 g and 3.03 g, resp., in 100 g of clove.
- Production of gallic acid from tara tannin by bacterial strains
- Production of gallic acid from tara tannin by bacterial strains. Deschamps, Alain M.; Lebeault, Jean Michel (Div. Procedes Biotechnol., Univ. Technol., Compiegne 60206, Fr.). Biotechnol. Lett., 6(4), 237-42 (English) 1984. CODEN: BILED3. ISSN: 0141-5492. DOCUMENT TYPE: Journal CA Section: 16 (Fermentation and Bioindustrial Chemistry) Bacterial strains identified as Klebsiella pneumoniae and Corynebacterium species degraded in a few hours a great part of pure tara (Caesalpinia spinosa) tannin or a crude water ext. of tara pod powder. Large amts. of gallic acid [149-91-7] were recovered, reaching 55% of the theor. yield in the best case. The feasibility of gallic acid prodn. by a biotechnol. process is discussed.
