The Flow Rate of the Condenser Cooling Water in the Distillation Process Increases the Quality and Quantity of Patchouli Oil

Table 3

Oil yield on several treatments of condenser water discharge and patchouli leaf drying.

Patchouli leaf drying	Condenser water discharge			Average
	1.74 L/min ()	1.08 L/min ()	0.48 L/min ()
	Oil yield (%)
5 days ()	1.40^A(a)	1.03^B(a)	0.34^C(a)	0.92^a
6 days ()	1.30^A(b)	0.90^B(b)	0.23^C(b)	0.82^b
7 days ()	1.23^A(c)	0.74^B(c)	0.17^C(c)	0.71^c
Average	1.33^A	0.89^B	0.24^C
