Achyranthes aspera Linn. is a well-known plant drug in Ayurvedic, Unani-Tibbi, Siddha, Allopathic, Homeopathic, Naturopathic & Home Remedies. The present communication deals with the pharmacognostic evaluation on the different parts of Achyranthes aspera Linn. (Amaranthaceae). Macroscopic and microscopic examinations of the different organ, observations and differential microchemical test has been carried out for the authentication of the samples. Physiochemical values such as the Moisture contents, percentage of total ash, acid insoluble ash, acid soluble ash, extractive values like petroleum ether-soluble extractives, ethanol-soluble extractives, methanol-soluble extractives and water-soluble extractives were calculated as well as colour reactions of powder and extract with different chemicals were performed. The extracts were subjected to qualitative screening test for various constituents. This revealed the presence protein, glycosides, alkaloids, tannins and phenolic compound, steroid reducing sugars and saponin glycosides. These observations will help in the Pharmacognostical identification and standardization of the drug in the crude form and also to distinguish the drug from its adulteration.

Weed Plant

Cassia obtusifolia Linn. is commonly known as “Takla” or “Chakunda” in India, a common weed, also used as vegetable Family-Caesalpiniaceae. Macroscopic and microscopic examinations of the different organ, observations and differential microchemical test have been carried out for the authentication of the samples. Physiochemical values such as the Moisture contents, percentage of total ash, acid insoluble ash, acid soluble ash, water soluble ash, extractive values like petroleum ether-soluble extractives, ethanol-soluble extractives, methanol-soluble extractives and water-soluble extractives were calculated as well as colour reactions of powder and extract with different chemicals were performed to observe fluorescence analysis. The extracts were subjected to qualitative screening test for various constituents. This revealed the presence protein, glycosides, alkaloids, tannins and phenolic compound, steroid reducing sugars, saponin glycosides and fats. These observations will help in the Pharmacognostical identification and standardization of the plant as a drug in the crude form and also to distinguish the material from its adulteration.

Objectives: In this study, systematic pharmacognostic study and preliminary phytochemical screening of the bark of Cascabela thevetia L. were carried out. Methods: The selected plant part was collected, processed and stored in an airtight container. From the bark different pharmacognostic studies like macroscopic and microscopic evaluation, physicochemical parameters, fluorescence analysis were done. Powdered bark was successively extracted by petroleum ether, chloroform, ethyl acetate, and methanol using a Soxhlet apparatus and finally macerated with the hydro-alcoholic solvent system (30:70). The preliminary phytochemical analysis and thin layer chromatography of the extracts were done to find the nature and number of the different phytoconstituents present. Results: Transverse microscopy reveals the presence of crystal oxalate, cork cell, starch granules, vascular bundle, phloem fiber, parenchyma cells, and collenchyma cells. Powder microscopy also showed the presence of cork cell, fiber and calcium oxalate crystal. Results obtained in different physicochemical analysis like total ash, acid insoluble ash, water soluble ash, alcohol-soluble extractive, water-soluble extractive, and moisture content were 8.67%, 0.83%, 5.33%, 4.53%, 12.27%, and 7.83% respectively. Phytochemical analysis showed the presence of alkaloid, flavonoid, triterpenoid, phytosterol, tannin, saponin, anthraquinone, carbohydrate and fatty acid in the different extracts. TLC (Thin Layer Chromatography) study revealed 4 spots in petroleum ether, chloroform, ethyl acetate, and methanol extracts and 3 spots in the Hydro-alcoholic extract with different solvent systems. Conclusion: The results obtained from the study will provide a reliable basis for identification, purity, and quality of the plant.

Pergularia daemia belongs to the family Asclepiadaceae, known to have anticancer, anti-inflammatory activity. Aim of the present study was to evaluate qualitative and quantitative phytochemical and antioxidant properties of ethanolic extracts of leaf, stem and root parts of P. daemia . Preliminary phytochemical analysis and in vitro antioxidant properties were evaluated by standard methods. The qualitative phytochemical analysis of P. daemia showed presence of flavonoids, tannins, alkaloid, phytosterol, carbohydrate, phenol, saponin, glycosides, terpenoids, steroids proteins and reducing sugars. Quantitative analysis showed polyphenol, flavonoid, flavonone, flavone and flavonol in P. daemia leaves, stem and root in considerable quantity. The in vitro antioxidant activity of P. daemia clearly demonstrated that leaf, stem and root parts have prominent antioxidant properties and was effective in scavenging free radicals.

AbstractThe effect of maleic hydrazide (MH) per se on bright tobacco was determined by comparing plants treated with MH to those without MH under conditions of good chemical sucker control. Sequential applications of each of five contact-type agents with MH one week later (Group I) were compared to dual applications of each of the same contact agents (Group II). In Group II suckers missed during applications were individually wetted to ensure excellent control. Sucker control was measured as 95 % for Group I and assumed to be 99 % for Group II. There were no agronomic differences between Groups I and II. In the visual warehouse appraisal, there was only a statistical difference for thin-bodied tobaccos between the two groups and a trend for slightly more heavy-bodied tobaccos in Group I. The chemical and physical analyses showed that filling value at 13 % moisture and equilibrium moisture content (EMC) measured at 60 % relative humidity were significantly lower in Group I than Group II. The result for EMC was questioned. Actual values for total alkaloids, total volatile bases minus nicotine, total ash, and alkalinity number of water-soluble ash were lower and reducing sugars were higher where MH was used. Except for EMC, the findings in this study reflected those established in studies where MH-treated and normally hand-suckered tobaccos were compared, but the differences here were generally not as great.

Antibacterial Potential

There is an alarming increase in the problem of resistance towards antibiotics amongst most of the pathogenic bacterial strains in recent years. This has drawn the attention of researchers around the world to search for novel and eco-friendly antibacterial compounds. Several biological sources have been explored in this respect but medicinal plants have taken a centre stage out of all. Plants have been known as a reservoir of number of bioactive compounds specially the antibacterial ones since time immemorial. Therefore, the present investigation was undertaken to analyze the antibacterial potential of the medicinal plant Achyranthes aspera. This study revealed that highest antibacterial activity was observed in the methanolic extract of stem against almost all test Bacteria. It showed maximum activity against E.coli (30 mm), followed by S. aureus (28 mm), Enterococcus sp.(25mm), Salmonella typhi ( 20 mm) and least activity was recorded in same extract against K.pneumoniae (6 mm). Four phytochemicals were screened in various solvent extracts. They are alkaloid, flavonoids, saponins and tannins.

<p>Shilajit (asphaltum)  is produced  by the long term humification  of dead plant material  and organic vegetable matter  by different micro-organisms and has great potential for the treatment of a variety of human conditions.  This treatise reviews its origin, sources, chemical composition, biological  and  commercial importance. Phytochemical analysis was done by standard methods to evaluate  different Shilajit (asphaltum) classes of compounds in different samples of shilajit  which are responsible for their  biological activity.  Shilajit`s anti-microbial activity has been evaluated  against four different bacterial strains viz., <em>Escherichia coli, Psuedomonas aeuroginosa</em>, <em>Klebisella pneumonia</em> and <em>Staphylococcus aureus. </em>Phytochemical analysis illustrated  that shilajit contains  terpenoids, cardiac glycosides, saponins and reducing sugars. Surprisingly,  some classes of compounds are absent in shilajit  viz., alkaloids, flavonoids, tannins and anthraquinones. . Shilajit showed no response towards halophytic bacteria and  negligible activity was shown towards other strains of bacteria. Since   anti-microbial activity is based on environmental factors  its activity varied  between locations.</p>
