The aim of this work was to develop and characterize a polyester matrix composite material based on canarium schweinfurthii Engl core granule. The particle size and the mass fractions of these cores used as fillers in this composite were the two optimization parameters. The experimentation of the twelve sample areas was based on the following optimization parameters: Three particles sizes of 80 1 2 3 ·m-3, which allows us to admit that this composite belongs to the family of light materials. The maximum compressive stress at break was obtained for the formulation 40% filler of size T3. This compressive stress at maximum rupture is in the range of 199.14 MPa. From 0% to 45% of filler, the flexural Young’s modulus of the composite increases whatever the particle size. The highest value is obtained for T2 particle size, i.e. 13.11 GPa. The static friction coefficient of the composite on wood increases as the filler content varies from 0.30 to 0.42. Thus, in view of the properties obtained, this composite can be used as alternative solutions in industrial applications, for the manufacturing of shoe heel, house ceiling, floors for housing and table support.

canarium odontophyllum is one of the underutilized fruits among the local community in Sarawak, Malaysia. The leaf extracts from C. odontophyllum (6.25 mg/ml to 50 mg/m) were screened against two Gram-positive bacteria (Staphylococcus aureus and Bacillus cereus) and two Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa). Extraction of the C. odontophyllum leaves using methanol produced the highest yield (5.46%) followed by water (4.0%) and acetone (2.83%) whereas hexane extracted the lowest yield (0.98%). Out of the four bacterial species tested, only S. aureus was found to be susceptible towards the C. odontophyllum leaves extract. Screening result using agar well diffusion method showed that the antimicrobial activity of the acetone and methanol extracts from C. odontophyllum leaves was concentration-dependent towards the growth inhibition of S. aureus. The MIC values for both MeOH and acetone extracts were 0.391 mg/ml. The MBC value of MeOH extract was twice its MIC value whereas the MBC and MIC values of acetone extract against S. aureus were the same. Phytochemical analysis showed that acetone, MeOH and water extracts contain flavonoid, tannin, terpenoid and phenol. These findings conclude that the leaves of C. odontophyllum may contain therapeutically-useful compounds against S. aureus, which are mostly concentrated in the acetone extract. As such, C. odontophyllum have the potential to be developed as an alternative treatment against Staphylococcus aureus-associated skin and soft tissue infections.

The preliminary study is aimed at evaluating the cytotoxic activity of crude extracts from the stem bark of canarium odontophyllum against colorectal carcinoma cell HCT 116. Result of the extraction yield showed that distilled water produced the highest yield (10.58%) followed by methanol (6.55%) whereas acetone extracted the lowest yield (4.58%) from C. odontophyllum stem bark. Phytochemical screening test revealed the presence of terpenoid, flavonoid, tannin, saponin and phenolic compound in all the stem bark extracts of C. odontophyllum. Acetone extract of C. odontophyllum stem bark showed significantly higher (p < 0.05) cytotoxic effect with IC50 of 0.062 ± 1.04 mg/ml compared to methanol extract with IC50 0.122 ± 4.92 mg/ml. No cytotoxic effect was observed by the aqueous extract despite its high extraction yield. In conclusion, acetone and methanol extracts from C. odontophyllum stem bark exhibited promising cytotoxic activity against human colorectal cancer cell line HCT 116 and paves way for further investigation in view of its mode of cancer cell death.
