Abstract Direct solvent extraction with hexane:ethyl acetate (90:10, v/v), saponification, and Soxhlet extraction with hexane were evaluated for their usefulness as extraction methods to determine vitamin E in peanuts and peanut butters. The direct solvent extraction procedure yielded higher values for each tocopherol homolog in peanut and peanut butter compared to the other methods. Coupling of the rapid, direct solvent extraction with normal phase chromatography on Si 60 provides a highly reproducible procedure to quantitate vitamin E in peanuts and peanut products. The overall % recoveries (means ± S.D.) of this study for α-, β-, γ-, and δ-tocopherol were 99.9 ± 3.29, 100.4 ± 11.7, 98.9 ± 5.94, and 100.3 ± 4.87, respectively. Limits of detection and limits of quantitation were 0.21, 0.06, 0.11, and 0.08 ng and 0.39, 0.14, 0.23, and 0.13 ng, respectively, for α-, β-, γ-, and δ-tocopherol. Repeatability, reproducibility, and accuracy of the methods were excellent with % CVs for accuracy of 1.19 (α-T), 1.55 (γ-T), and 2.69 (δ-T). Accuracy was not acceptable for β-T due to its extremely low concentration in the peanut and because peak purity was not obtained for β-T. The method was applied to other seeds with good success. Major homologs were γ-T in peanuts, pecans, cashews, walnuts, and pistachio; α-T in almonds; and α-T3 in macadamia.

In this study, ultrasound-assisted extraction (UAE) was compared with conventional extraction methods, including conventional solvent extraction without agitation (CSE), conventional solvent extraction with agitation at 50 rpm (CSE50) and 150 rpm (CSE150), for the extraction of phenolic compounds from coconut (Cocos nucifera L.) husk. The extraction yield, total phenolic content (TPC) and total flavonoid content (TFC) were examined. The antioxidant capacity of C. nucifera extracts was determined by using 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) and 2,2’-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assays. Experimental results showed that UAE gave the highest extraction yield, TPC, TFC and antioxidant capacities (ABTS and DPPH), followed by CSE150, CSE50 and CSE, respectively. UAE was found to be more effective than conventional extraction methods. Conventional solvent extraction with higher agitation speed exhibited higher extraction efficiency than those with lower agitation speed and without agitation.
