Chemical characterisation and biological effects of Juniperus foetidissima Willd. 1806

The present study was designed to define the phenolic and terpene profile, antioxidant and anti-inflammatory activity of methanol extracts and essential oils of the leaves and seed cones of funiperus foetidissima species, on which there has been little previous research. The content of 44 phenolics in extracts was determined using LC-MS/MS. A comparable qualitative composition, including dominant compounds catechin, quercitrin, epicatechin, rutin and quercetin-3-O-glucoside, was found in both extracts. GC MS analysis showed a simple terpene composition, with monoterpenes dominant and sabinene most abundant compound, 39.9% in leaves and 29.9% in seed cones. Antioxidant activity was determined by several assays. All results of antioxidant tests were comparable to BHT, a well-known synthetic antioxidant. A novel method for estimation of anti-inflammatory potential by means of inhibition of COX-1 and 12-LOX activity was described. Essential oils showed significant anti-inflammatory activity, especially of leaves. To conclude, J. foetidissima showed great bio potential, and its usage in production of food and beverages should be considered. (C) 2013 Elsevier Ltd. All rights reserved.
