3.3 Fatty acid composition of Qingjinju seed oils
The fatty acid composition of the Qingjinju seed oils is detailed in
Table 3. Qingjinju seed oils contained a variety of major fatty acids
including oleic (34.08-35.49%),
linoleic (29.79-30.79%), palmitic (17.17-17.76%), stearic
(8.02-8.94%), linolenic (6.50-6.81%), and palmitoleic (1.24-1.53%)
acids. This differs from the report by Manaf el
at4, which found that
linoleic (31.8%), oleic (29.6%), and palmitic (21.4%) acids were the
predominant fatty acids. This is likely due to differences in the
production region, as has been observed for grapefruit (C.
paradisi )15,
17, mussami (C.
sinensis )15,
17, and kinnow (C.
reticulata )15,
17.
There were significant differences
between several of the fatty acid profiles due to the method used for
extraction. For example, oleic and linoleic acid content significantly
varied across all three extraction methods, which is in agreement with
results reported by Pradhan et
al.36 The unsaturated
fatty acid content in the oils extracted using the different methods
ranged from 73.12 to 73.54%, which was higher than C. sinensis ,C. paradisi , C. aurantium , and C.
reticulata11
