A Review on Pharmacognosy, Pre-Phytochemistry and Pharmacological Analysis of Tridax Procumbens

Pharmacognostical parameters for the leaves of Tridax procumbens L were studied with the aim of drawing the pharmacopoeial standards for this species. Macroscopical and microscopical characters, pre-phytochemical and pharmacological Studies. The determination of these characters will aid future investigators in their Pharmacological analyses of this species. The Pre-phytochemical screening revealed the presence of alkaloids, carotenoids, flavonoids (catechins and flavones), fumaric acid, fl-sitosterol, saponins and tannins. It is richly endowed with carotenoids, saponins, oleanolic acid and ions like sodium, potassium and calcium. Luteolin, glucoluteolin, quercetin and isoquercetin have been reported from its flowers. It has known for its number of pharmacological activities like hepatoprotective activity, antiinflammatory, wound healing, antidiabetic activity, hypotensive effect, immunomodulating property, bronchial catarrh, dysentery, diarrhoea and to prevent falling of hair promotes the growth of hair, and antimicrobial activity against both gram-positive and gram-negative bacteria. The leaf juice possesses antiseptic, insecticidal and parasiticidal properties, as a remedy against conjunctivitis and is used also to check haemorrhage from cuts, bruises and wounds insect repellent. It is also used as bioadsorbent for chromium (VI). This review focus on folk occurrence and the wide pharmacological activities of Tridax procumbens.
