Ultrasonic Extraction of Oil from Caesalpinia spinosa (Tara) Seeds

Figure 2

(a) Tara seed oil yields with different particle sizes. Samples of dried tara powder (10 g) ground to different sizes (20–40, 40–60, 60–80, 80–150, and >150 mesh) were extracted with petroleum ether. Ultrasonic extraction was performed for 45 min at 250 W and 30°C. (b) Tara seed oil yields with different liquid–solid ratios. Dry tara powder (10 g, 60–80 mesh) was extracted with different liquid–solid ratios (8 : 01, 10 : 01, 12 : 01, 14 : 01, and 16 : 01). Ultrasonic extraction was performed at 250 W and 30°C.
