Flemingia vestita (Family: Fabaceae), is a leguminous root crop commonly found in the northeastern region of India. The tubers are anthelmintic and eaten unpeeled by the natives against gastrointestinal worm infection. The present study deals with the pharmacognostic studies on the rhizome of crude drug F. vestita. Our preliminary phytochemical studies of the powdered rhizome revealed the presence of alkaloid, carbohydrate, protein, amino ac-ids, phenol, tannic acid flavonoid, phytosterols, saponins, fat, oil, gum and mucilage. The physico-chemical, morphological, histological parameter may be proposed as parameters to establish the authencity of F. vestita.

Pharmacognostic evaluation is the first and foremost step to determine the identity and to assess the quality and purity of the crude drug. Notonia grandiflora is a perennial succulent plant, widely used in traditional medicinal system without standardisation. Notonia grandiflora has reported to possess various pharmacological activities such as analgesic and antinociceptive, anti-inflammatory, antimicrobial, antibacterial, antifungal, and antipyretic. In the present study, pharmacognostic studies of root, stem, and leaf of Notonia grandiflora is carried out in order to standardize the plant. For standardization of plant material morphological and anatomical characterization was carried out. Physico-chemical parameters viz. ash content, extractive values, heavy metal content was carried out. Transverse section of Notonia grandiflora root shows periderm, cortex xylem parenchyma showing tracheids and phloem. Stem shows epidermis covered externally by cuticle, cortex, vascular bundles and pith. Calcium oxalate crystals, leaf and branch traces were also present in the cortical region of the stem. Leaf lamina showed palisade cells and spongy parenchyma in mesophyll region and anisocytic type of stomata. Powder characters and physico-chemical parameters such as moisture content, extractive values, ash content and heavy metal analysis were performed. The results of current study could be served as a diagnostic tool for the standardization of this medicinal plant and will be helpful in characterization of the crude drug.

A genus of plant belongs to the family Solanaceae well distributed in India more than 26 species which are found naturalised in India. Solanum torvum Sw. is a medium sized flowering plant in the Solanaceae family that is found in India, Malaysia. Transverse section of lamina showed the adaxial part has thick, short hump; the midrib and the adaxial hump have thin, angular epidermal cells. The upper part of adaxial hump has a few layers sclerenchyma cells. The inner layer of the adaxial midrib also has few layers of thick walled cells. The ground tissue consists of wide circular thin walled parenchyma cells with narrow inter cellular spaces. The vascular system of the midrib showed bi-collateral structure. Non glandular, profusely branched, thick walled, lignified epidermal trichome occurs as both on the veins and lamina. Physico-chemical standards such as Foreign Matter, Total Ash, Water Soluble Ash, Sulphated Ash, Loss on Drying, Water Soluble Extractive, Alcohol Soluble Extractive and Crude Fiber Content in percentage were estimated. Preliminary phytochemical screening of appropriate solvent extracts showed the presence of Alkaloids, Amino Acids, Carbohydrates, Cellulose, Lignin, Fats & Fixed Oils, Flavonoids, Glycosides, Tannins, Proteins, Starch, Steroids and Triterpenoids and absence of Volatile Oil, Mucilage and Pectin. Microscopic analysis and other parameters were informative and provide valuable information in the identification, standardization of Solanum torvum leaves.

The present work focus to evaluate the physicochemical and preliminary phytochemical studies on the seeds of family Caricaceae. The plants resources which are used in pharmaceutical formulation standardization was carried out on the basis of organoleptic properties, physical characteristics, and physico-chemical properties. Different Physicochemical parameters ash values, extractive values, loss on drying, foreign matter, fluorescence analysis, and pH were evaluated. Macroscopical characteristics and Physicochemical parameters like total ash, acid insoluble ash and water soluble ash were found to be 83.7%, 71.7% and 61.5% w/w respectively. Hexane, ethyl acetate, ethanol and water soluble extractive values (hot)were 7.6%, 11.6%, 27.4%, 37.5%w/w respectively. The pH of 1% and 10% aqueous solution was found to be 3.57 and 3.78 respectively. Preliminary phytochemical screening showed the presence of Tannins, Proteins and amino acids, Glycosides, Phenolic compounds, Carbohydrates, Saponins, Alkaloids and Flavonoids. Thin layer chromatographic studies also had been done on ethanolic and hexane extracts. HPTLC fingerprinting is a valuable method for the quantitative determination of phytochemicals present in plant extract. These studies aim to investigating referential information for correct identification and standardization of this plant secondary metabolites.

Morinda umbellataLinn. (Family Rubiaceae) is commonly known as “Nuna” in Tamil and “Pitadaru” in Sanksrit. The leaves in conjunction with certain aromatics in the form of decoction are used in diarrhoea and dysentry. The genuine sample ofM.umbellatawas collected. As part of the study genuine leaf, stem and root samples were collected and subjected to anatomical investigations. The air-dried leaf powder was extracted with different solvent systems such as petroleum-ether (40-60° C), benzene, chloroform, ethanol and sterile water and preliminary phytochemical analysis of the extracts including TLC and paper chromatographic assays were done and the Rfvalues were determined. Physico-chemical characters, fluorescence characters and extractive values of the leaf powder in different solvent systems were also determined. The pharmacognostical parameters studied, may be used as a tool for the correct identification of the plant and also to test the adulterants if any.

Fracturing under ultrahigh vacuum (UHV, p ≤ 10-9 Torr) produces membrane fracture faces devoid of contamination. Such clean surfaces are a prerequisite foe studies of interactions between condensing molecules is possible and surface forces are unequally distributed, the condensate will accumulate at places with high binding forces; crystallites will arise which may be useful a probes for surface sites with specific physico-chemical properties. Specific “decoration” with crystallites can be achieved nby exposing membrane fracture faces to water vopour. A device was developed which enables the production of pure water vapour and the controlled variation of its partial pressure in an UHV freeze-fracture apparatus (Fig.1a). Under vaccum (≤ 10-3 Torr), small container filled with copper-sulfate-pentahydrate is heated with a heating coil, with the temperature controlled by means of a thermocouple. The water of hydration thereby released enters a storage vessel.
