The consumption and commercial exploitation of Allanblackia Clusiaceae seed oils is of current interest. The favorable physicochemical characteristics of Allanblackia oil solid at room temperature; high stearic acid content lend food products that contain it i. Such considerations are important for individuals prone to cardiovascular disease or with hypercholesterolemia. Domestication projects of several Allanblackia species in tropical Africa are underway, but wildcrafting of fruits to meet the seed demand still occurs. Proper species authentication is important, since only authenticated oil can be deemed safe for human consumption. The chemical constituency of Allanblackia seed oils, and potential roles of these phytochemicals in preventive strategies e.

We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos.
Allanblackia klainei Pierre ex A. Recently, the international food industry has become interested in the fat as a natural solid component for margarines and similar products[ ]. The seeds contain a fat that is solid at ambient temperatures.
Only traces of other fatty acids are present. Fruits are stored under a cover of leaves to allow the fruit pulp to disintegrate. To extract the seeds, fruits are crushed between the hands and seeds are rubbed clean. To extract the fat, seeds are dried and crushed; the resulting mass is mixed with water and boiled until the fat separates and floats to the surface, from where it is scooped off[ ].
More modern hydraulic and screw press equipment is now also used[ ]. The seeds are eaten in times of food scarcity[ ]. The fruit is large, up to 30cm long by 10cm in diameter with upward of seeds borne within in a translucent mucilage[ ].
Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally. A decoction of the inner bark is taken to treat diarrhoea, dysentery and stomach aches[ , ].
A decoction of the inner bark is used as a mouthwash to relieve the pain of toothache[ , ]. The bark is anodyne.
A decoction of the bark or leaves is taken to treat asthma, bronchitis and cough[ ]. The bark is pounded and rubbed on the body to relieve painful conditions[ ]. Sap squeezed from the bark is a component of a medicine used to treat urethral discharge[ ]. Sap expressed from a crushed up mixture of the bark, combined with that of Mammea africana, maleguetta and sugar-cane, is taken as a remedy for urethral discharge[ ].
A decoction of the whole fruit is used to relieve elephantiasis of the scrotum, though this may simply be based on the Theory of Signatures because of the size and shape of the fruit[ ].
A prenylated xanthone, named allanxanthone A, has been isolated from the bark, as well as 1,5-dihydroxyxanthone and 1,5,6-trihydroxy-3, 7-dimethoxyxanthone.
The compounds isolated showed moderate in-vitro cytotoxicity against the KB cancer cell line[ ]. Plant material from the Congo has been reported to contain abundant flavonins in the bark and roots, some tannins, and traces of steroids and terpenes[ ].
Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil. Oil Trees are left on the farms when clearing the land for cultivation and managed especially for shading cocoa[ ].
Other Uses An oil obtained from the seeds is used for soap making and in the cosmetics industry[ ]. Small twigs are used as chew-sticks or toothpicks[ ]. Twigs have been used as candlesticks[ ]. A sticky, yellow resin is obtained from the inner bark[ ]. The heartwood is pale red or brown; it is usually fairly distinctly demarcated from the thick, pinkish beige sapwood. The grain is fairly straight, texture medium to coarse; the lustre is low.
The wood is fairly hard, fairly durable, and moderately resistant to termites[ ]. It is resistant to marine borers[ ]. When dry it saws well, but green wood may spring on conversion. It is fairly easy to work with hand and machine tools[ ]. It is used locally, but is of secondary importance. In Nigeria it is used in construction of local houses[ ]. Carbon Farming.
It grows best in areas where the maximum mean annual temperature ranges from 24 - 33c, whilst the minimum can fall below 10c. It prefers a mean annual rainfall in the range 1, - 2,mm[ ]. Grows best in a sunny position[ ].
Prefers well-drained soils especially lithosols[ ]. Common in the wild on strongly leached, acid soils with pH 3. Under natural conditions, trees start flowering after about 12 years, with the flowering occurring during a large part of the year. Fruits take nearly a year to mature and ripe fruits are also found during a large part of the year[ ].
The degree of maturity of fruits on the tree can not be estimated, so mature fruits are left to drop to the ground and are then collected[ ]. The fat from the seeds of Allanblackia floribunda is very similar in composition to that of Allanblackia parviflora and Allanblackia stuhlmannii[ ]. A dioecious species, both male and female forms need to be grown if fruit and seed are required[ ]. Celsius Fahrenheit:. Plants For A Future have a number of books available in paperback and digital form.
Our new book to be released soon is Edible Shrubs. Seed - germination takes 6 - 18 months and germination rates are very low[ ]. Keeping the fruits for a few months on damp sites covered with banana leaves and buried partially and scarification of the seedcoat improve germination rates only slightly[ ].

This unusual fatty acid content has the right properties for many different food and cosmetic products making them commercially interesting. Vegetative propagation studies on A. In addition, the effects of protecting side tongue new grafts with non perforated translucent plastic, perforated translucent plastic and aluminium foil were assessed. Under nursery conditions, side tongue grafts were significantly more successful
