Oil was extracted from avocado, mango and native pear seed through the mechanism of mechano
thermal techniques. In this process no solvent was added for the purpose of the oil recovered rather the
mechanism of extraction was mainly mechanical and distillation process. The different oils recovered
from the process were subjected to pharmaceutical analysis to ascertain the properties of some minor
bioactive compounds and their compositions in relation to the three samples of the agro-based seeds
examined. The parameters analgised were total tocopherols, β – tocopherol, α – tocopherol, γ –
tocopherol, total carotenoids, β - cryptoxanthin, β - carotene, total phenolicsa and total flavonoidsb.
The results of the oil recovered from the agro-based seeds illustrates the following characteristic of
biological properties in terms of the bioactive compound value of total tocopherol value pof 51.27,
67,28 and 70.20 for mango, avocado and native pear seeds and for α – tocopherol value of 42.32, 54.30,
and 60.14, β – tocopherol value of 1.89, 2.24 and 2.79, γ – tocopherol value of 2.06, 2.92, and 2.86,
total carotenoids value of 8.81, 9.70, and 9.95, β – cryptoxanthin value of 8.50, t.61, and 7.96, β –
carotene value of 4.85, 7.18, and 7.94, total phenolicsa value of 610.70, 803.30, and 5053.11, total
flavonoidsb value of 1.55, 1.89, and 2.76 of mango, avocado and native pear seeds respectively. This
research has revealed that the native pear seed is more medicinal for pharmaceutical benefit when used
compared to avocado and mango seed as demonstrated by the properties of the minor bioactive
compound of the 3 varieties of the agro-based materials sampled. The research also, compared the cost
implication of solvent extraction and mechano-thermal approach of oil recovered from these seeds and
conclude that the mechano-thermal techniques is the better than the solvent method.
