Abstract

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 check for this species in other resources 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.
