“…Several diterpenes were isolated from different parts of pines (Simard, 2007). Earlier Karepova et al (1983) reported that the aqueous extract of the woody verdure of Pinus sylvestris contained aliphatic mono-, di-and tricarboxylic acids and benzene carboxylic acids. Among aromatic acids, they found benzoic acid in the largest amounts.…”

In traditional Algerian medicine, Pinus halepensis (Mill.) resin is used as antimicrobial, anti-inflammatory, analgesic, wound healer, for the treatment of respiratory and urinary diseases. In the present study, a lyophilized aqueous extract (LAE) of Pinus halepensis (Mill.) resin is subjected to chemical composition analysis by gas chromatography coupled to mass spectrometry (GC/MS), antioxidant activity was evaluated in vitro using 2,2-diphenyl-b,picrylhydrazyl (DPPH) and β-carotene bleaching assays. LAE of Pinus halepensis (Mill.) resin was also tested for its potential activity against four dermatophytic fungi: Trichophyton rubrum, Trichophyton equinum, Trichophyton mentagrophytes, Trichophyton tonsurans. Results showed that LAE of Pinus halepensis (Mill.) resin contained 64.57% of aromatic compounds. This extract contains also succinic acid, sugars and alcohol sugars, alkaloids and other compounds that represent respectively 0.58%, 6.45%, 0.87% and 2.05%. The obtained extract exhibited satisfying antioxidant activity with an inhibition percentage of 93.76±0.41 at a concentration of 300 µg/mL and IC50 of 83.64µg/mL by the DPPH method. The tested extract showed also a good antioxidant activity using β-carotene test. At resin concentration of 100 µg/mL antifungal tests showed, inhibition rates of 58.9%, 58.44%, 41.36% and 34.43% against T. tonsurans, T. equinum, T. rubrum and T. mentagrophytes respectively. Upon the obtained results, this extract can be used as external treatments for wounds to prevent oxidation and fungal infections.
