Justicia secunda is a plant used in Congo by Jehovah’s Witnesses, well known for their refusal of blood transfusions, against anaemia. This provides vhal possible molecular basis for earlier reports on the anti-sickling properties of anthocyanins from some Congolese plants and their use in the management of sickle cell disease by Congolese traditional healers.

On a pilot plant scale, water extracts were processed using an extraction-concentration procedure achieved in a three-step process, including ultrasound-assisted water extraction followed by cross-flow microfiltration of the crude extract and its concentration by reverse osmosis. Industrial Crops and Products Polyphenol extraction and characterization of Justicia secunda Vahl leaves for traditional medicinal uses.

Justicia secunda

Publications des agents du Cirad. Water extracts of Justicia secunda leaves are used by village communities in southern countries to prepare traditional medicines at home. Anthocyanins from Justicia secunda were found to possess anti-sickling activity.

These ions are bound to membrane proteins resulting in dehydration and loss of red blood cell deformability and cell-to-cell adherence.

At each step of the pilot plant process, the co-products obtained were analyzed for total polyphenol and total flavonoid contents by the UV-vis spectrophotometric method.

Emmel, Itano and osmotic fragility tests were used to test aecunda effect of anthocyanin extracts from Justicia secunda leaves on haemoglobin S solubility and sickle cell membrane stability. Sickle cell disease or drepanocytosis is caused by the polymerisation of abnormal haemoglobin S when oxygen tension decreases.

The beverage is avhl obtained by boiling the plant in water. It secinda also been postulated that the red cells of patients with sickle cell disease contain a higher than normal concentration of calcium ions. The process allowed a better leaf water-extraction of polyphenol compounds than the homemade extraction. Site du Cirad Annuaire des sites du Cirad.

Treated SS red blood cells recovered a normal, classical biconcave form with a radius of 3.

These findings suggest that anthocyanin extracts play a role in both stabilising the red blood cell membrane and inhibiting polymerisation of haemoglobin S. Anthocyanins extracted jussticia some Congolese plants used in traditional medicine against sickle cell disease have recently been shown to have anti-sickling activity in vitro.

As the processing conditions were milder than for homemade preparations, the extract obtained was enriched in natural leaf flavonoids. This lead to the changes in jussticia shape of red blood cells and anaemia. The solubility of deoxyhaemoglobin S increased and the osmotic fragility of drepanocytes decreased upon treatment with anthocyanin extracts.
