Lichen metabolites as UVB filters

Lichen metabolites as UVB filters. Lichen metabolites show photoprotector capacity. Fernandez, E.; Quilhot, W.; Gonzalez, I.; Hidalgo, M. E.; Molina, X.Several reagents with their cas registry numbers 548-89-0 and 479-20-9 are used here.; Meneses, I. (Escuela de Quimica y Farmacia, Universidad de Valparaiso, Valparaiso, Chile). Cosmetics & Toiletries, 111(12), 69-70, 73-74 (English) 1996 Allured. CODEN: CTOIDG. ISSN: 0361-4387. DOCUMENT TYPE: Journal CA Section: 62 (Essential Oils and Cosmetics) Section cross-reference(s): 8 A good relation between the skin temp. differences and sun protection factor values measured in vivo. The highest values were obsd. for gyrophoric acid, pannarin, and divaricatic acid. Thus, the lichen metabolites play a paramount role against UV radiation. .

Gyrophoric acid

Gyrophoric acid. Maksimov, O. B.; Baraboi, V. A.; Krivoshchekova, O. E.; Stepanenko, L. S.; Mishchenko, N. P. (Pacific Ocean Institute of Bio-Organic Chemistry, Vladivostok; Kiev Scientific-Research Roentgen-Radiological and Oncological Institute, USSR).In this article, certain chemicals are used. One of their cas registry numbers is 548-89-0 U.S.S.R. SU 1255137 A1 7 Sep 1986 From: Otkrytiya, Izobret. 1986, (33), 13-14. (Union of Soviet Socialist Republics) CODEN: URXXAF. CLASS: ICM: A61K035-78. APPLICATION: SU 84-3779171 10 Aug 1984. DOCUMENT TYPE: Patent CA Section: 63 (Pharmaceuticals) Section cross-reference(s): 11 Gyrophoric acid is obtained by extn. of lichens with an org. solvent followed by evapn. The yield is increased and the procedure is simplified by using Umbilicaria rossica as the source of raw material and by extg. 1st with CHCl3 and then with boiling Me2CO. .
