a The total policosanol yields are directly expressed as Yield (%) = (m/M) × 100, where m is the weight of the final policosanol product (g), and M is the weight of the samples (g).
b Data from Dunford et al. [15].
c Data from Wang et al. [21].
d Data calculated according to Wang et al [21].
e Data were from Zhu, in which insect wax was saponified to prepare policosanol [32].
