A preliminary pharmacognostical study on leaves and flowers of Michelia champaca L. Magnoliaceae

Abstract

The present investigation was conducted to establish pharmacognostical profile for the leaves and flowers of Michelia champaca L. (Magnoliaceae) in order to establish its complete profile to aid in its identification and avoid confusion in taxonomic level for different species of the same genus. The study included macroscopical, organoleptical, microscopical and preliminary phytochemical analysis of the leaves and flowers. The study of the organoleptical evaluation revealed the presence of colour, odour and texture. The microscopic analysis showed the differences in cell structures, arrangement and shape of leaves and flowers. The physical characters of various solvent extracts showed the presence of colour, odour and consistency of the powdered leaves and flowers. Finally, the preliminary phytochemical analysis confirmed for the presence of alkaloids, saponins, tannins, glycosides, carbohydrates, amino acid, flavonoids and sterols in both leaves and flowers. The present findings may be used to establish the authenticity of leaves and flowers of Michelia champaca L. for their proper identification and standardization in order to collect raw plants for the preparation of herbal drugs.

In silico Study of Chromane Ring Compound Rubranonoside from Plumeria rubra as Anticancer Potential

“…Cancer is characterized by uncontrolled cell division by overcoming the signalling pathways involved in normal cell proliferation leading to apoptosis, extensive angiogenesis and metastasis. If the cell cycles particular checkpoints are targeted then it may provide lead for novel method of treatment [10]. The regulatory proteins, cyclins and their effector counterparts the cyclin dependant kinases have been identified as prominent targets in cell cycle mechanism.…”

Antioxidant Activity and Phytochemical Screening of Michelia Champaca L. Flowers

“…according to the book "The Tretise of Indian Medicinal plants" 5 Preliminary phytochemical analysis of various extracts of Michelia champaca L. leaves and flowers showed the presence of alkaloids, tannins, glycosides, carbohydrates, amino acids, flavonoids and sterols. 6 Antibacterial and free radical scavenging activity of Michelia champaca L. was done on its flowers. In this study hexane and ethyl acetate extract showed strong antioxidant activity with IC50 values of both extracts were found to be 10µg/ml and 250 µg/ml respectively.…”
