摘要

To understand their importance, we performed a comparative study on fixed, total, and essential oils from the seed and aril of Myristica fragrans. The total, essential, and fixed oils content of nutmeg (34.47%, 5.95%, and 26.43%, respectively) and mace (22.55%, 8.79%, and 23.73%, respectively) showed varied oil content. The major fatty acid in mace fixed oil (MFO) and mace total oil (MTO) was palmitic acid (33.30% and 33.11%. respectively), whereas, in nutmeg fixed oil (NFO) and nutmeg total oil (NTO), it was myristic acid (62.52% and 58.20%, respectively). MTO exhibited the highest total phenolic (~ 4596 mg gallic acid equivalent/100 g) content. The phenolics and the flavonoids (mg/100 g), such as catechin (25.40 ± 16.11) and quercetin (13.86 ± 2.34), were high in MFO. Rutin (20.61 ± 3.91) and gallic acid (10.69 ± 1.58) were highest in MTO. Ferulic acid (8.26 ± 0.49) was highest in NTO, and synergic acid (24.72 ± 3.41) in NFO. The MFO showed the highest antioxidant activity (53% radical scavenging activity by DPPH; 34 M Trolox equivalent/ 100 g of oil by TEAC assay; 104 M Trolox equivalent/ 100 g of oil by FRAP assay), correlating with the polyphenols content. The fixed oils showed higher overall antioxidant activity than essential oils.
