PHARMACOGNOSTICAL STANDARDISATION OF PLUMERIA ACUTIFOLIA (POIR) BARK (original) (raw)

Abstract

Plumeria acutifolia (Poir) syn Plumeria rubra (Linn) is a herbal plant belonging to genus Plumeria of Apocynaceae family. The Plumeria acutifolia Poir syn Plumeria rubra L isa native of Maxico. It is also known as Frangipani, Temple tree, Jasmine tree, Pogoda tree. It is a medicinal and ornamental plant widely used in perfumery. The root bark is bitter, pungent, carminative, laxative, ulcers and useful in leprosy. In Mumbai (India), it is used as an intermittent, like cinchona. In Ayurveda system of medicine it is used in malaria, fever, antiseptic and stimulant. The microscopy shows bark composed of cork cells and small size scelenchymatous cells. The cortex is wide and parenchymatous, numbers of sclereids are widely distributed in cortex region. The cortex also shows the presence of calcium oxalate crystals. The water soluble, chloroform soluble, alcohol soluble and petroleum ether soluble extractive values were determined. The total ash, water soluble ash, acid insoluble and sulphated ash were observed. The preliminary phytochemical screening revealeds the presence of carbohydrate, alkaloids, glycosides, tannins, iridoids and saponins in various bark extract of plant. The pharmacognostical studies of plant have been carried out. This study will help curb substituation and adulteration of the plant material.

Dried Bark of Plumeria acutifolia (Poir) The foaming index, swelling index and pH of the extract are tabulated in Table 7. It is the quick method for the resolution study of crude drug of suspicious specimen, when physical and chemical methods produce inadequate results. The plant material may be identified from their adulterants on the basis of fluorescence nature. Results are described in Table 4. Quantitative Studies The successive extracts obtained were subjected to investigation for various phytoconstituents present, like alkaloids, carbohydrates, glycosides, terpenoids, sterols, tannins, phenolic compounds, saponins, iridoids, protein and amino acid.
