The antioxidant properties of the methanol extract of leaves and flowers of Erica arborea and the ethyl acetate, butanol and water soluble fractions were investigated. The ethyl acetate extract was found to be the richest for phenolic and flavonoid content which showed the highest antioxidant activity.

    ABSTRACT: Aim The present study was carried out to evaluate the antioxidant and anti-inflammatory capacity, and acute toxicity of Moroccan Erica arborea leaves. Methods Antioxidant capacity was assessed by diphenyle-picryl-hydrazyl (DPPH), phosphomolybdate (PPM) and ferric reducing antioxidant power (FRAP) tests and anti-inflammatory capacity was evaluated by hind paw oedema model using carrageenan-induced inflammation in rat. The acute toxicity was evaluated using mice. Results Acute toxicity of ethanolic extract of E. arborea showed no sign of toxicity at dose of 5 g/kg B.W. Our extracts have important antioxidant properties. The efficient concentration of the ethanolic extract (10.22 μg/ml) required for decreasing initial DPPH concentration by 50% was comparable to that of standard solution butyl-hydroxy-toluene (BHT) (8.87 μg/ml). The administration of ethanolic extract at doses of 200 and 400 mg/kg B.W. was able to prevent plantar oedema and exhibited a significant inhibition against carrageenan-induced inflammation when compared to the control group (NaCl 0.9%) but comparable to those of diclofenac (reference drug). Conclusions Our results show that the leaves of E. arborea may contain some bioactive compounds which are responsible for the antioxidant and anti-inflammatory activities observed here. Our finding may indicate the possibility of using the extracts of this plant to prevent the antioxidant and inflammatory processes.

    • "Erica spp. is often used in east of Morocco by hyperlipidaemic subjects as an alternative therapeutical tool to treat hyperlipidaemia (Harfani et al., 2007), and has also been used in folk medicine as a diuretic and antiseptic agent (Harfani et al., 2007; Akkol et al., 2007). The phytochemical study of this plant showed that tannins, proanthocyanidols and flavonoids represent major compounds of its flowers (Harfani et al., 2007; Akkol et al., 2007; Ay et al., 2007). Oxidative stress plays an important role in the pathogenesis of various diseases such as atherosclerosis, alcoholic liver cirrhosis and cancer (Sundararajan et al., 2006; Tawaha et al., 2007; Nanasombat and Teckchuen, 2009).

    ABSTRACT: Polyphenols and particularly flavonoids are widely appreciated for their potential beneficial health effects, like antioxidant or anticarcinogenic activities. The aim of this study was to determine the antioxidant activity of extracts of some shrubs that grow spontaneously in Portugal (Pterospartum tridentatum, Cytisus scoparius and Erica spp.) and then to correlate it with total phenolic and flavonoid compounds. The Folin-C method was used to determine total phenols while a colorimetric method with aluminum chloride was used for the determination of total flavonoids. Regarding the determination of antioxidant activity, two distinct methods (DPPH assay and beta-carotene bleaching test) were used. It was concluded that all the extracts presented relevant antioxidant activity and there was a positive linear correlation between antioxidant activity index and total phenolic content.

    • "Akkol et al. (2008) stated that Erica arborea displayed remarkable anti-inflammatory and antinociceptive activities. Antioxidant activity of Erica arborea has been also demonstrated (Ay et al. 2007). As far as our literature survey could ascertain, there is no information concerning the pharmacologic effects of Erica carnea and Bruckenthalia spiculifolia. "

    ABSTRACT: Quantitative analyses and investigation of antioxidant activity of herb and dry ethanolic extracts of five species from Ericaceae family (Arbutus unedo L., Bruckentalia spiculifolia Rchb., Calluna vulgaris Salisb., Erica arborea L. and Erica carnea L.) were performed. Total polyphenols, tannins and flavonoids were determined spectrophotometrically and arbutin content was measured both spectrophotometrically and by HPLC coupled with DAD detection. Antioxidative properites of the ethanolic extracts were tested by means of FRAP (total antioxidant capacity), lipid peroxidation and DPPH free radical scavenging activity. A significant amount of arbutin was detected only in Arbutus unedo. All samples investigated showed excellent antioxidant activity. The best inhibition of lipid peroxidation has been shown by Bruckentalia spiculifolia herb extract (62.5 microg/ml; more than 95%), which contained the highest amount of flavonoids (11.79%). The highest scavenging activity was obtained with leave extract of Arbutus unedo (IC50 = 7.14 microg/ml). The leaves of A. unedo contained a small amount of flavonoids but high content of non-tannins polyphenols.
