Botanical Profile
Tetraclinis articulata is an evergreen tree or large shrub of the Cupressaceae. The species occurs primarily in northwestern Africa and in smaller western Mediterranean populations. It has scale-like, articulated-looking branchlets and small cones and is adapted to dry, warm sites. The species is known for a pale, brittle resin called sandarac. Its wood, sometimes traded as thuya or root wood, is also important in craftsmanship. From a raw-material perspective, resin, wood, fragrance fractions and technical products must be considered separately.
Phytochemistry
Sandarac resin consists predominantly of diterpenoid resin acids and neutral resin constituents, supplemented by small amounts of volatile components. Abietane, pimarane and labdane structures and related oxidised terpenoids are described. Compared with softer balsams, sandarac is a hard, brittle resin with historically important lacquer and varnish properties. Composition and quality depend on origin, resin age, oxidation, purity, foreign resins and mineral admixtures.
Traditional Uses
In the Mediterranean region and North Africa, sandarac was traditionally used as a resin raw material for incense, lacquers, varnishes, writing materials and craft applications. In European art and craft history, sandarac played a role as a component of protective coatings. The wood of Tetraclinis articulata was valued for decorative work and veneers. The raw material therefore stands particularly within a resin, fragrance and material-historical tradition.
Current Research
Modern research addresses resin chemistry, diterpene profiles, wood quality, essential fractions, ecological adaptation, forest management, Mediterranean dry habitats and sustainable use. Analytical studies investigate terpenoids, resin ageing, authenticity and technical applications. Compared with classical medicinal plants, the emphasis is more strongly on raw-material chemistry, materials science, ecology and origin assurance.
