INTRODUCTION

The Medicinal plants are useful for healing as well as for curing of human diseases because of the presence of phytochemical constituents. Phytochemicals are naturally occurring in the medicinal plants, leaves, vegetables, and roots that have defence mechanism and protect from various diseases. Phytochemicals are primary and secondary compounds. Chlorophyll, proteins, and common sugars are included in primary constituents and secondary compounds have terpenoid, alkaloids and phenolic compounds. Medicinal plants play a major role in meeting the medical and health needs of about 70% of populations in developed and developing countries, which serve as an important resource for the treatment of various maladies and illnesses [1].

In developing countries, there is an increasing attempt to incorporate the traditional medicines, especially herbal preparations in the local healthcare systems and modernized people are increasingly turning to herbal medicine [2]. Globally, about 85% of the traditional medicines used by different ethnic groups inhabiting various terrains for primary health care are derived from plants, especially in India; medicinal plants are widely used by all sections of the population with an estimated 7500 species of plants used by several ethnic communities [3]. The medicinal importance of a plant is due to the presence of some special substances like alkaloids, glycosides, resins, volatile oils, gums and tannins etc. The active principles usually remain concentrated in the storage organs of the plants [4].

The plant Crateva magna belonging to family Capparaceae is a well-known plant in the herbal world for its wide range of use in medicinal purposes. It is used as an anti spasmodic, hypotensive, anti inflammatory, hypoglycemic, anti protozoal, Anthelmintic, analgesic purposes. It is also used to increase appetite and for the treatment of various diseases e. g. rheumatism and nephrotoxicity, arthritis, urinary disorders [5]. The root, bark and leaf is used to treat fever, urticaria, snake bite poisoning, diseases of vatam, urinary calculi, ulcers, skin eruptions [6]. Since time immemorial medicinal plants have been in use to treat various diseases which includes peptic ulcer, cancer, diabetes, arthritis, hepatitis, acute and chronic inflammations and neurodegenerative diseases [7]. Medicinal plants are important sources for new chemical substances with potential therapeutic effects [8].

MATERIALS AND METHODS

Identification and authentication

The selected plant Crateva magna (Lour) DC. (Leaf) was collected from Places in and around Trichirappalli, identified using Flora of Presidency of Madras and authenticated by the Botanist of St. Joseph’s College, Trichirappalli and a voucher specimen was deposited at RAPINAT Herbarium, Department of Botany, St. Joseph’s College Trichirappalli, Tamilnadu, India.

Tests for identity, purity, and strength

Determination of botanical standards [9]

The Microscopic studies of Crateva magna (Lour) DC. (Leaf) was examined. Physicochemical constants such as Foreign matter, Total ash, moisture content, Acid insoluble ash, and water soluble ash and Extractive value such as Hexane, Chloroform, Ethyl acetate, Alcohol was determined [10]. The Preliminary Phytochemical Analysis of various extracts was also determined [11]. The HPTLC Analysis [12] and LC MS Analysis [13] also analyzed.

Preliminary phytochemical analysis of dry powder and aqueous extract of Crateva magna (Lour) DC. (Leaf) showed the presence flavones, steroids, glycosides, sugar, alkaloids, quinones, phenols, coumarin and lignin.

TLC, HPTLC Profiles of Crateva magna (Lour) DC. (Leaf)

Stationary phase: Silica Gel 60 F254

Use of high-performance liquid chromatograms, thin-layer chromatography, atomic absorption spectroscopy, gas chromatography and where necessary more sophisticated techniques such as NMR and LC/MS has now become common in complementary medicines manufacturing industries to ensure the quality of plant materials and final product [14]. The emphasis on good manufacturing practice has steadily increased over years. This spectrum indicates may be the presence of bioactive compounds.
