Melicope borbonica (Bory) T.G.Hartley


distribution in Africa (wild)
Protologue: Allertonia 8(1): 287 (2001).
Family: Rutaceae

Synonyms

  • Aubertia borbonica Bory (1804),
  • Euodia borbonica (Bory) Engl. (1896).

Vernacular names

  • Catafaye, petit bois de catafaye, bois de catafaye blanc (Fr).

Origin and geographic distribution

Melicope borbonica is endemic to Réunion.

Uses

The wood and leaves macerated in alcohol are externally applied as a liniment to treat rheumatism and for wound healing. Leaf and stem bark extracts were taken in the past as a tonic, depurative and sudorific. The aromatic leaves and stem bark are added to local rum.

Properties

Extracts of the leaves of Melicope borbonica yielded the acetophenone xanthoxylin and the coumarins scoparone and psoralen. The minor coumarins limettin, bergapten and cedrelopsin were also isolated, as well as several sesquiterpenes, eugenol, methyleugenol and the lignan sesamin. Furthermore, ethanolic leaf extracts yielded isorhamnetin, dillenetin and several methoxyflavones.

Scoparone, limettin and xanthoxylin exhibited moderate antifungal activity against Candida albicans and Penicillium expansum. Different leaf and stem extracts showed moderate antifungal activity against Cladosporium cucumerinum. The extracts did not show any significant anti-inflammatory, antiviral and antitumour activities in vitro.

Description

Much-branched shrub, up to 7 m tall. Leaves opposite, 1(–3)-foliolate, strong-smelling; stipules absent; petiole variable in length, (0.7–)2.5–8 cm long; leaflets elliptical, (4–)7–9(–14) cm × (2–)3–5 cm, apex acute, base rounded to cuneate, margin entire, thin, papery when dry. Inflorescence a small, axillary panicle, 1–4 cm long. Flowers unisexual, regular, 4-merous, small; petals white, glabrous or with finely appressed hairs outside; male flowers with filaments c. 1 mm long; female flowers with superior ovary, short-hairy, style thin, 0.5 mm long, stigma small. Fruit a 1–4-lobed capsule 6–8 mm long, each lobe almost free, 1-seeded. Seeds rounded, black, shiny, acute on one side.

Other botanical information

After a major revision, all Euodia species from Madagascar and the Mascarene islands were transferred to Melicope. An orthographic variation of Euodia is Evodia. Melicope comprises c. 235 species occurring from the Malagasy and Indo-Himalayan regions to Hawaiian and Marquesas Islands and New Zealand. Of the 19 species that occur in the Indian Ocean islands, 11 species are endemic to Madagascar and 6 species are endemic to Réunion. Melicope chapelieri (Baill.) T.G.Hartley occurs both in Réunion and Madagascar and Melicope obtusifolia (DC.) T.G.Hartley occurs both in Réunion and Mauritius.

Ecology

Melicope borbonica grows in degraded forest, at 200–1500 m altitude. It flowers from December–March.

Genetic resources

Melicope borbonica is common and not threatened by genetic erosion.

Prospects

Melicope borbonica contains coumarins and several other compounds with moderate pharmacological activity. Unless additional pharmacological tests reveal interesting results, Melicope borbonica will remain of limited importance.
