ABSTRACT: Studies have revealed that Acer truncatum seed oil has a high nutritional value. However, the constituents
of seed oil may vary depending on the extraction and separation techniques employed. Here, we aimed to explore
the effect of three extraction methods on A. truncatum seed oil. After comparing the extraction rate, acid value
(AV), moisture content (MC), fatty acid composition, Fourier transform infrared spectroscopy characteristic, and antioxidation activities of three A. truncatum seed oil samples extracted by refluxed with petroleum ether (S1), petroleum
ether extraction combining ultrasonic power (S2) and solvent lixiviation at room temperature (S3). The results showed
that S3 had a higher extraction rate than the others, but lower unsaturated fatty acid content and DPPH scavenging rate.
The DPPH scavenging rate and nervonic acid (NA) concentration of S2 sample were higher than the others, but with
larger MC and lower extraction rate. As for S1, the unsaturated fatty acid content was higher than the others; but the
extraction rate was lower, and the acid value was higher. Therefore, the results demonstrated that extraction methods
should be selected according to the actual application target, as different methods presented different advantages
and disadvantages. However, further studies on some other properties (such as antioxidant activity) of the extracted
A. truncatum seed oil are required.
