The Present work deals with the study of exudate of Dacryodes edulis with
regards to various seasonal physicochemical properties of the purified solids exudate, acid
hydrolysis product and saponification product like charring temperature (
oC) (195.73 ± 4.75,
190 ± 7.9, 190 ± 3.4, ); flash point (
oC) (105 ± 5.0, 100 ± 7.9, 100 ± 3.4); moisture content %
(1.32 – 1.35, 1.05 – 1.08, 1.00 - 1.10); ash content (%) (1.77 – 1.85, 1.21 – 1.31, 1.26 -1.37);
lignin content (%) (7.77 – 7.85, 6.21 – 6.31, 5.26 – 5.37); electrical conductivity (μS/cm) (28.40
-29.20, 32.10 – 33.00, 30.30 – 30.90); density (g/cm3) (0.76 -0.77, 0.94 – 0.98, 0.88 – 0.98);
melting point (
oC) (61.08 – 73.35, 58.69 – 73.35, 55.35 – 65.67). The physicochemical
characteristic of
Dacryodes edulis
is found to be fluctuated with seasonal variations during the
present investigation. The correlation coefficient showed positive relationship among the
properties. The study reveals that exudate of Daryodes edulis can be tapped in large quantity in
the dry season and is rich in lignin content but the seasons does not affect the properties.
