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.

Objective: Anacardium occidentale, Achyranthes aspera, and Aegle marmelos are the common plants found in North and South India. The present study identifies the active phytochemicals and antioxidant properties in various extracts derived from dried bark, whole aerial parts, and leaves of the above plants. Materials and Methods: Phytochemical screening included extracts of pet ether, hydroalcoholic, and aqueous. The antioxidant activity was determined by measuring total phenolic contents (TPC), 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity (RSA), and total flavonoid content (TFC). Results: The phytochemical screening of A. occidentale, A. aspera, and A. marmelos of dried bark, whole aerial parts, and leaves revealed the presence of flavonoids, phenols, tannins, and proteins. It also contains alkaloids and glycosides. Hydroalcoholic extract of A. occidentale, A. aspera, and A. marmelos showed highest TPC 0.125 mg/g, 0.256 mg/g, and 0.254 mg/g, respectively. TFCs 0.094 mg/g, 0.145 mg/g, and 0.121 mg/g and highest DPPH RSA with the half maximal inhibitory concentration of 125 μg/mL, 105.58 μg/mL, and 98.89 μg/mL compare to the standard ascorbic acid of 21.65 μg/mL. Conclusion: This study showed that the hydroalcoholic extract of A. occidentale, A. aspera, and A. marmelos is potential source of natural antioxidants.

As in other districts of Nepal, medicinal plants have played a significant role in the life of local people of Baitadi and Darchula districts by providing products for trade, subsistence and traditional therapies. Present study analyzed the pharmacological activities of the species which had the highest informant consensus factor. The use of Asparagus racemosus as galactogogue with consensus factor 0.97, Berberis asiatica for eye troubles with 1.0, Cordyceps sinensis as tonic and longevity with 0.97, Curculigo orchoides as tonic and aphrodisiac with 0.96, Nardostachya grandiflora for epilepsy with 0.97 and Phyllanthus emblica as diuretic with 0.97 possessed the highest consensus factors and greatest affinity to the Ayurveda and phytochemical findings. Phytochemical screening and validity assessments of the medicinal plant widely used in traditional therapies are worthwhile. The findings with the maximum affinity of informant consensus factors and phyto-chemical validations provide the potential to identify which plants are most likely to be useful in the treatment of diseases.

Phytochemicals are a complex group of bioactive non-nutrient compounds of the plant kingdom and an integral part of the human diet. The present research was carried out to screen the phytochemicals in raw and germinated foxtail millets. The screening showed the presence of carbohydrates, alkaloids, fixed oils and fats, terpenoids and cardiac glycosides in both raw and germinated foxtail millets. Amino acids were not detected in raw but present in germinated, indicating in prominent in the bio-availability of amino-acids due to germination. The absence of quinones indicated that extracts have not undergone any oxidation during storage.

The objective of this study is to search families of chemical compounds and to evaluate subacute toxicity of decoction of Landolphia owariensis liana bark on wistar rat. To identify the family compound chemical staining reactions and / or precipitation was used. Subacute toxicity study was conducted using OECD method 404. 15 rats of both sexes were divided into five groups. They were received for each lot, distilled water (control), 50, 300, 2000 and 5000 mg/kg body weight of decoction every 24 hours orally for 28 days (OECD 404). Body weights, hematological, biochemical and histological parameters of the liver and kidneys were analyzed. The results of phytochemical screening showed that the decoction of L. owariensis contains sterols, polyterpenes, polyphenols and flavonoids. It is rich in chemical substances with antioxidant properties (polyphenols and flavonoids). For toxicity assessment, no significant changes in body weight between control and treated groups and no physiological disturbances were observed after 28 days of treatment. Analyzes of hematological and biochemical parameters revealed no toxicity of the decoction. No mortality was also recorded for the methods used. It is nontoxic to rats, even at high doses (5000 mg/kg body weight). As a result, liana bark of this plant could be used for effective therapeutic purposes.

AbstractAnatomical analyses found that leaves of Euphorbia nicaeensis ssp. glareosa are isolateral, amphistomatous, with two layers of palisade cells on the adaxial and one on the abaxial side. Laticifers are present by vascular bundles, in palisade and spongy tissue. Stem laticifers are located in the pericyclic ring, adjacent to the phloem, in cylinder parenchyma and medullar rays. The structure of pleiochasium and dichasium peduncle is similar to the stem structure. Plants from typical steppe habitat show more xeromorphic features. Phytochemical screening of extracts showed presence of catecholes, flavonoids, tannins, saponins, free quinone derivatives and absence of anthocyanins, leucoanthocyanins, alkaloids, steroid compounds and essential oils. Our results showed that the examined taxon was partially susceptible to the action of reactive oxygen species, such as O2·− and ·OH. The higher quantities of ROS thus provoked an antioxidative response from the plant, both in an enzymatic and non-enzymatic manner. Stable anatomical structure, presence and distribution of laticifers and effective antioxidant properties when exposed to ROS, make Euphorbia nicaeensis subsp. glareosa potentially interesting for further pharmaceutical and phytochemical examinations.
