Optimization of oil extraction from Pitanga (Eugenia Uniflora L) leaves using Simplex Centroid Design (SCD)
Simplex centroid design (SCD) was employed to optimize the mixing of petroleum ether, n-hexane, methanol and ethanol for the extraction of oil (PLO) from Pitanga (Eugenia uniflora L.) leaves, via Soxhlet extraction. The highest yield (54%) of Pitanga leaf oil (PLO) was obtained with 100% ethanol...

| description | Simplex centroid design (SCD) was employed to optimize the mixing of petroleum ether, n-hexane,
methanol and ethanol for the extraction of oil (PLO) from Pitanga (Eugenia uniflora L.) leaves, via
Soxhlet extraction. The highest yield (54%) of Pitanga leaf oil (PLO) was obtained with 100% ethanol
and the lowest yield (16%) from the mixture of methanol (33.3%)/hexane (33.3%)/ethanol (33.3%). The
coefficient of determination (R2) of the model equation obtained was 0.91, while the adjusted R2 and
predicted R2 were 0.8729 and 0.951, respectively. The saponification value (S.V.), iodine value, acid
value and free fatty acid (FFA) are 35.34 mgKOH/g, 72.97 mgI2/g oil, 32.41 and 16.30 mgKOH/g,
respectively. |
