General Uses Top
Suggest a correction!Common products:
- Seed oil (non‑edible) extracted for industrial applications.
- Timber (wood) harvested from mature trees.
Industrial and craft applications:
- Seed oil serves as a feedstock for biodiesel; after transesterification it meets ASTM D6751/EN 14214 specifications.
- Seed oil is used in soap manufacturing due to its saponification value (≈185 mg KOH g⁻¹) and high unsaturated fatty‑acid content.
- Bark yields a natural brown/red dye employed on protein fibers and contributes hydrolyzable tannins for leather tanning.
Colorants and tanning:
- The bark and seed coat provide a reddish‑brown natural dye traditionally applied to cotton and wool. The dye contains hydrolyzable tannins (≈15–20 % polyphenols) that impart colour and mordancy, and the tannins are used in leather tanning.
Wood and fiber:
- Wood has a moderate density (≈0.65 g cm⁻³) and low shrinkage, making it suitable for light construction, furniture, tool handles, and charcoal production.
Properties relevant to use:
- Seed oil composition: linoleic acid ≈55 %, oleic acid ≈30 %; iodine value ≈120 g I₂ 100 g⁻¹; saponification value ≈185 mg KOH g⁻¹ – attributes that enable biodiesel conversion, soap making, and other industrial oil applications.
- Bark dye: high tannin content gives durable coloration and tanning capability.
- Wood: density and dimensional stability support structural and craft uses.
Sustainability and sourcing:
- Picralima nitida is native to West Africa; harvest of seeds, bark, and timber is generally localized and can be sustainable under community‑based management. However, commercial extraction for oil and dye can pressure wild populations, prompting recommendations for agroforestry cultivation and selective harvesting guidelines to maintain resource availability.
