Extraction and GC-MS Analysis of Oil Extract from Christmas Tree (Araucaria Heterophylla) Leaf

For ease of powdering, the leaves were oven-dried for five minutes at 800C after being air-dried for twenty-one days. The cold extraction process was then used to extract the oil. The oil extract was dark brown in colour. Nineteen chemicals were found in the oil extract by GCMS analysis, beginning with 2(1H)-Naphthalenone, 4a,5,8,8a-tetrahydro-1,1,4a-trimethyl-, trans (8.23%), Palmitic acid (6.27%), and Bicyclo [7.2.0]. 4,11,11-trimethyl-8-methylene, undec-4-ene (4.94%) Hibaene (16.18%), 13-Isopimaradiene (1.14%), Atis-16-ene (5.82%), 1,5,9-Decatriene, 2,3,5,8-tetramethyl- (1.31%), β-Selinene (8.75%), Kaur-16-ene (15.29%), 9,12,15-Octadecatrienoic acid, (Z,Z,Z)- (1.42%), Cembrene (3.4-d) [1,3]oxazole-4-carbonitrile (1.20%), neophytadiene (1.35%), abietic acid (2.50%), ferruginol (4.07%), and 5-(furan-3-yl)-2-methylpent-1-en-3-ol (7.10%). These findings suggested that the biological activities of the oil extract from Christmas tree leaves (Araucaria heterophylla) may have prospective uses in the pharmaceutical and cosmetic industries.
