Катрафай

Katrafay is the essential oil steam-distilled from the bark of Cedrelopsis grevei (Baill. & Courchet, 1906), a tree endemic to western and southern Madagascar. The genus Cedrelopsis belongs to the Rutaceae (subfamily Spathelioideae, formerly segregated as Ptaeroxylaceae). The tree grows to 9–15 metres in dry deciduous forest and scrubland across the provinces of Toliara, Mahajanga, and Antsiranana, at elevations from sea level to 900 metres. In Malagasy, katrafay means “bitter juice.”

The bark oil is dominated by sesquiterpene hydrocarbons. Cavalli et al. (2003, Flavour and Fragrance Journal) identified 114 components in a single commercial sample by GC, GC–MS, and ¹³C-NMR. Major constituents: (E)-β-caryophyllene (1.3–12.5%), α-copaene (4.9–11.0%), ishwarane (1.0–17.4%), β-elemene (0.2–9.6%), α-selinene (1.1–9.4%), δ-cadinene (up to 4.9%), α-humulene (up to 3.3%). A later study by Raoelison et al. (2008) found four distinct chemotypes: one dominated by eudesmols (α-eudesmol 9.9–37.8%), another by α-pinene (2.1–30.0%) and copaborneol (4.7–20.0%), a third by ishwarane (13.7–22.1%), and a fourth by cadinane-skeleton compounds. The variation is geographic, not seasonal.

Steam distillation of bark yields 0.9–1.7% oil (14-hour distillation; Panjaïtan et al., 2014), though artisanal operations typically report 0.4–0.6%. The oil is pale yellow to amber, with a warm, woody-spicy, balsamic character — drier than sandalwood, more resinous than atlas cedar, with a persistent camphoraceous-medicinal edge from copaborneol. A red-earth undertone grounds the profile.

Katrafay remains a niche material in Western perfumery. Most production serves Malagasy traditional medicine, where bark decoctions treat fatigue, rheumatic pain, and inflammation — pharmacological studies have confirmed analgesic and anti-inflammatory activity in the oil. In natural perfumery, the high sesquiterpene content (67–99% depending on chemotype) makes it a powerful fixative. It anchors woody, earthy, and balsamic compositions without the sweetness of benzoin or the smokiness of birch tar.
