| Abstract: |
| In order to provide theoretical basis for the introduction of excellent germplasm resources of olive in Yunnan province, the oil was extracted by Soxhlet method from olive fruit with different varieties from different introduced areas in Yunnan province, and the fatty acid composition and squalene content of the oil were determined by gas chromatography. The results showed that the fatty acid composition of the olive oil from the same variety of olive fruit from different introduced areas was similar and mostly clustered in one group. The olive oil from different varieties of olive fruit had different fatty acid compositions, but the differences in the fatty acid composition of the olive oil from the same variety of olive fruit at different maturity levels were not significant. The squalene content of the olive oil obtained from different varieties varied considerably, and the difference between the lowest value and the highest value was 8.2 mg/g. In conclusion, the fatty acid composition of olive oils from the same variety of olive fruit is generally genetically stable, and the olive oil from different varieties of olive fruit has different fatty acid compositions and significant differences in the content of squalene. |
