Ochrosia borbonica J.F.Gmel.

Protologue
Syst. nat. 2: 439 (1791).
Family
Apocynaceae
Vernacular names
Bois jaune, quinquina du pays (Fr).
Origin and geographic distribution
Ochrosia borbonica is endemic to the Mascarene Islands (Réunion and Mauritius).
Uses
In Réunion a small piece of the bark is boiled and the decoction is sweetened with honey and is drunk to treat loss of appetite, hypotension and constipation, and to reduce fever, e.g. in case of malaria. The bark soaked in wine is taken daily to purify the blood; the bark soaked in rum or water is taken before meals to reduce stomach cramps. In Mauritius the bark boiled with leaves is taken to treat fever. It is also widely taken as a tonic and stomachic and is applied against stomach cramps, as a bath or drink. It is also used against childhood eczema, locally known as ‘tambave’.
The wood was formerly used as timber for making household utensils.
Production and international trade
Ochrosia borbonica is used at a local scale only, and because it has become rare, it is no longer traded much.
Properties
Research on active constituents in Ochrosia has focused on anticancer compounds following the isolation of the indole alkaloids ellipticine, elliptinine, 9-methoxy-ellipticine and isoreserpiline from the Asian Ochrosia elliptica Labill. Many Ochrosia spp. have since been subject to investigation of their alkaloid content, and the production of ellipticine in in-vitro grown callus from Ochrosia elliptica has been successful.
The bark of Ochrosia borbonica is rich in indole alkaloids and contains mainly ellipticine, 9-methoxy-ellipticine, reserpiline and isoreserpiline. Ellipticine and 9-methoxy-ellipticine show antitumour properties, but also disturb biological membranes, which makes their utilization in medicines impossible.
Semisynthetic derivatives show higher activities against cancer cells and are less toxic. So far, only one ellipticine derivative, celiptium® (N-methyl-9-hydroxy-ellipticine, as acetate salt) has been introduced onto the market for treatment of metastatic breast cancer. This drug also shows significant activity against several leukaemia and melanoma cell lines. Ellipticine derivatives and analogues are also reversible non-competitive inhibitors of cholinesterases and interact with muscarine receptors. The ellipticine derivative hydroxy-methyl-ellipticine shows strong antiviral activities and is being extensively screened in clinical anti-Aids treatments.
Description
Small tree up to 15 m tall, glabrous, except for the fringed sepals, with white latex; bole up to 40 cm in diameter; bark dark grey, fissured; branches with ring-shaped leaf scars. Leaves in whorls of 4, simple and entire; petiole 1–3.5 cm long, widened into a stipule at base; blade obovate to elliptical, 3–25 cm × 1.5–5 cm, base decurrent into the petiole, apex rounded, retuse, obtuse or acute, pinnately veined with numerous lateral veins at right angles to the midrib. Inflorescence a terminal cyme, but often seemingly axillary, many-flowered; peduncle 2–12 cm long; bracts scale-like. Flowers bisexual, regular, 5-merous, fragrant, sessile; sepals free, ovate, 2.5–3 mm long, thick, subtended by a sepal-like bracteole; corolla tube 7.5–10 mm long, cylindrical, slightly widened around the stamens, white with pink or red throat, lobes elliptical, 6–13 mm × 3–7 mm, apex rounded, spreading; stamens inserted 5–7 mm from the base of the corolla tube, included, filaments short; ovary superior, consisting of 2 carpels fused at base, style 2.5–4 mm long, split at base, ending in a conical pistil head. Fruit consisting of (1–)2 free ellipsoid drupes, 3.5–4.5 cm × 2–3 cm, apex rounded or apiculate, indehiscent, smooth, with 2 lateral ridges, mesocarp fibrous, each drupe 1–2-seeded. Seeds elliptical, flattened, 1.5–2.5 cm long, winged.
Other botanical information
Ochrosia comprises about 30 species from the Mascarene Islands and Seychelles to South-East Asia, the Pacific and northern Australia. New Caledonia is particularly rich in endemic species. Ochrosia belongs to the tribe Rauvolfieae, together with the well-known genus Rauvolfia.
Growth and development
Ochrosia borbonica flowers almost throughout the year, with a peak in January and February. Fruits are mainly observed from November to February. The fruits float with their thick fibrous mesocarp and are dispersed by sea currents. Likewise, the seeds float because of cavities in the endocarp. The seeds germinate readily when washed ashore. Natural regeneration of Ochrosia borbonica is very slow. It is also often not more than a shrub in the semi-arid vegetation.
Ecology
Ochrosia borbonica occurs in forest, up to 1250 m altitude.
Propagation and planting
Ochrosia borbonica can be propagated by seed or by cuttings. In Mauritius attempts are being made at propagating Ochrosia borbonica by ripe-wood cuttings, and plantlets are present in nurseries of the Ministry of Agriculture.
Genetic resources
In Mauritius and Réunion, Ochrosia borbonica has become rare because of habitat loss and destructive harvesting of the bark. It is now confined to remnants of forest and the risk of genetic erosion and extinction is very real for this species. It is classified as endangered on the IUCN Red List. Although Ochrosia borbonica is officially protected, pieces of bark collected from the wild can still be found on markets in Réunion.
Prospects
The indole alkaloids isolated from Ochrosia borbonica possess interesting anti-cancer and anti-viral activities. This potential can only be realized if the future of the species is secured.
