Hybanthus enneaspermus belonging to the family Violaceae commonly known as spade flower, is a small shrub growing to a height of 60cm with pink-purple spade shaped flowers. Ionidium suffriticosum, Viola suffriticosa, Ionidium enneaspermum and Viola enneaspermum are the synonyms for the plant. Entire plant is of medicinal importance and is widely used in Ayurveda and Siddha systems of medicine. Dipeptide, alkaloids, aurantiamide acetate, isoarborinol, sitosterol, sugars, flavonoids, catechins, tannins, anthraquinones and amino acids are the constituents present in the plant. In Southwest Nigeria the plant is locally known as Abiwere, used by Traditional birth attendants to make delivery less laborious. Hybanthus enneaspermus shows interesting medicinal properties like anti-hyperlipidemic activity, free radical scavenging activity, nephro protective activity, antioxidant activity, anti-arrhythmic activity, anti-infertility activity, anti-allergic, analgesic activity and anti-microbial activity. This article as a review on the plant, its phytochemistry and its reported pharmacological activity.Keywords

Standardization was carried out on the basis of detailed botanical evaluation of the leaves which includes morphology and microscopy as well as WHO recommended physico-chemical studies. The results of the standardization may throw a immense light on the botanical identity of the leaves Ravenala madagascariensis Sonn., which may furnish a basis of judging the authenticity of the plant and also to differentiate the drug from its adulterants and other species.
Ravenala madagascariensis Sonn., (Strelitziaceae), also known as Visirivazhai in Tamil, is a native of Madagascar, widely cultivated for its distinctive habit in tropical and subtropical regions. In addition to its ornamental nature, this tree has been widely used in traditional medicine for the treatment of diabetes and kidney stone problems. The seeds are reported to be antiseptic. The leaves of Ravenala madagascariensis Sonn., have close resemblance with Musa leaf. Hence pharmacognostical standardization will contribute to the differentiation of Ravenala madagascariensis Sonn. leaves from that of Musa paradisiaca. The anatomy of leaf showed squarish upper epidermis. The lower epidermis was stomatiferous. Cyclocytic stomata, druses, raphides, mesophyll with tannin bodies, lobed sclereids remain the characteristic features of the leaf microscopy. Physicochemical parameters were evaluated and fluorescence analysis were carried out.
Thus the study employs the correct identification of standardization of the drug in crude form.
