Abstract:

Soxhlet method was applied to extract oil from Psidium guajava seed, in the present study. The extraction conditions were optimized by single-fact and orthogonal tests. Results indicated that the most significant factor influencing extraction yield of oil from Psidium guajava seed was temperature, followed by extraction time and solid to liquid ratio in turn. When extracting Psidium guajava seed with petroleum ether at the material to liquid ratio of 1 : 10 (W/V) ) for 3 h at 90 ℃, the best extraction effect could be obtained, and the extraction yield of Psidium guajava seed oil was 12.82%.

Key words: Psidium guajava, seed oil, extraction technology, orthogonal test
