Title : PHYTOCHEMICAL ANALYSIS OF Gyrinops walla AND COMPARISON WITH Aquilaria malaccensis
Abstract : Agarwood is a fragrant dark resinous wood formed in the heartwood of Aquilaria sp. (Thymelaeaceae), especially in A. malaccensis. The aromatic resin, agarwood, is used for the world’s most expensive perfumes. Gyrinops walla (Thymelaeaceae) is an evergreen tree which grows in wet zone regions in Sri Lanka. Recently, it has been identified that G. walla possesses agarwood producing ability, which is similar to other species in family Thymelaeaceae. The objective of the present study was to preliminary identification of phytochemicals present in G. walla and to compare them with A. malaccensis which was the true agarwood resin forming species. Air dried coarse powders of different stem samples and leaf sample of G. walla and a stem sample of A. malaccensis were used and phytochemicals were extracted with each sample using soxhlet extractor with dichloromethane at 70 °C. After extraction, solvent was evaporated under reduced pressure and crude was re-dissolved in ethyl acetate for the phytochemical screening, using GC-MS. An external standard method was used to identify peaks and analyte concentrations in the chromatogram. From the stems, sixteen phytochemicals were identified in A. malaccensis and thirteen were found in G. walla all presented in agarwood resin. Out of those, nine compounds were found to be common in both species. Also, few important phytochemicals were identified from G. walla leaves. Therefore, G. walla could be confirmed as a species with significant influence on social, economic and natural environment in Sri Lanka and globally as an alternative of expensive agarwood resin for perfumery industry.
