Prevention And Cure

Nature is a unique source of structures of high phytochemical diversity, many of them possessing interesting biological activities and medicinal properties. Phytochemicals ensure safe, eco-friendly and most effective drug for animal use. Veterinarians use these phytochemicals with the knowledge from traditional system and modern pharmacology. High cost of allopathic medicine is one of the major contributing factors in loss of productive livestock and animal productivity. Many plants have been identified which show promising abilities in disease prevention and cure. Phytochemicals can be used either by feeding whole plant parts or by the process of extraction of these chemicals and delivering in concentrated forms. The pharmacological activities of plants are attributed to certain active principles, namely alkaloids, glycosides, fats, oils, tannins, saponins etc. The use of cheap and easily available phytochemicals can thus be made by taking a leaf out of the ethno-veterinary practices. Although the effects of natural remedies may seem slower, the results are sometimes better on the long run especially with respect to chronic diseases. The horizon of phytochemicals has to be explored and exploited to create a “green treatment” protocol to develop an ecofriendly and toxin free production system that is beneficial for existence of both human and animal population in the near future.

As per WHO reports, about three-quarters (65-80%) of the world’s population seek plants or plant-derived natural products for various diseases. The slow discovery of new synthetic molecules and rising resistance in microbes against existing ones has triggered an alarm for speeding up the development process for new molecules. Traditional system(s) of medicine and plant resources has been foresighted again by researchers to circumvent the situation. This review represents various plant genera which, either as a whole plant or their parts, have been reported possessing antimicrobial properties during the last decade. Before 2007, literature is already well cited in various books and reviews.

Cannabis sativa L. is a controversial crop due to its high tetrahydrocannabinol content varieties; however, the hemp varieties get an increased interest. This paper describes (i) the main categories of phenolic compounds (flavonoids, stilbenoids and lignans) and terpenes (monoterpenes and sesquiterpenes) from C. sativa by-products and their biological activities and (ii) the main extraction techniques for their recovery. It includes not only common techniques such as conventional solvent extraction, and hydrodistillation, but also intensification and emerging techniques such as ultrasound-assisted extraction or supercritical CO2 extraction. The effect of the operating conditions on the yield and composition of these categories of phenolic compounds and terpenes was discussed. A thorough investigation of innovative extraction techniques is indeed crucial for the extraction of phenolic compounds and terpenes from cannabis toward a sustainable industrial valorization of the whole plant.

Abstract Background In modern therapeutics, various human pathological disturbances were treated with the plant-based products. Waltheria indica Linn, a perennial herb, was commonly used in traditional medicine worldwide against various ailments such as cough, dysentery, diarrhea, bladder disorder, hemoptysis, inflammations, neuralgia, wounds, and ulcers. Main body The shrub was majorly distributed in tropical, subtropical regions and exists in many distinct local forms. Both the crude extracts and purified compounds from the whole plant and its parts showed wide pharmacological properties like antioxidant, analgesic, sedative, anti-bacterial, anti-fungal, and anti-parasitic. The phytochemical profile and traditional usage highlight the potency of the plant in the treatment of microbial infections and inflammatory diseases. Yet, additional studies are required for the confirmations of its traditional uses against other diseases. More detailed understanding of anti-cataract, anti-diabetics, asthma, anemia, and anti-cancer mechanism has to be explored. Though many research articles on the proposed plant are available, there has been a rising concern in the therapeutic property, especially on the alkaloids and flavonoids from this plant for drug design. Conclusion This article aims in a systematic and updated review on distribution, botany, traditional uses, phytocompounds, and relevant biological activities from each part of the plant. The information was collected from databases like PubMed, ScienceDirect, Web of Science, Google Scholar, books, dissertation, and reports via academic libraries that included more than 100 articles published since 1937. This ethnopharmacological study of the plant may create new insight into drug discovery to develop important novel leads against various biological targets.

Specific Symptoms

The terms used to describe symptoms of delayed senescence in soybean often are used inconsistently or interchangeably and do not adequately distinguish the observed symptoms in the field. Various causes have been proposed to explain the development of delayed senescence symptoms. In this article, we review published reports on delayed senescence symptoms in soybean, summarize current research findings, provide examples of terms related to specific symptoms, and present an overview of the results of a multi-state survey directed to soybean growers to understand their concerns about delayed soybean senescence. Some of these terms, such as green bean syndrome and green stem syndrome, describe symptoms induced by biotic factors, while other terms describe symptoms associated with abiotic factors. Some delayed senescence terms involve the whole plant remaining green while other terms include just the stem and other plant parts such as pods. In the grower survey, 77% reported observing soybean plants or plant parts that remained green after most plants in the field were fully mature with ripe seed. Most respondents attributed these symptoms to changes in breeding and choice of cultivars. At the end of this article, we standardized the terms used to describe delayed senescence in soybean.

Background: Developing the high-efficiency and low-risk small-molecule green-nematocide is the key of effective control of the nematodes. Paeonol, is a naturally occurring phenolic compound, isolated from the root bark of Paeonia suffruticosa and the whole plant of Cynanchum paniculatum. Due to its crucial phenolic ketone skeleton, modern biological science research has indicated that paeonol has a wide range of biological activities. The structural modification of paeonol into paeonol carbonyl hydrazone derivatives is a potential approach for the development of novel nematodes, which showed more toxicity than paeonol. However, there are no reports on the nematicidal activity of paeonol carbonyl hydrazone derivatives to control Heterodera glycines. Results: We always endeavor to discover and develop biorational natural products-based pesticidal agents, 4 significant intermediates and 21 novel 3/5(3,5)-(di)nitro/chloropaeonol carbonyl hydrazone derivatives were prepared, and their structures well characterized by 1H NMR, HRMS, MS, and mp. Due to the steric hindrance, the substituents on the C=N double bond of all hydrazine compounds adopted E configuration. Results of nematicidal activity revealed that, among all compounds, especially 5-nitropaeonol (5) and 3,5-dinitropaeonol (7) displayed the most potent nematicidal activity H. glycines in vivo with LC50 values of 0.0323 and 0.0367 mg/mL, respectively. Conclusion: It suggested that for the 3/5(3,5)-(di)nitro/chloropaeonol carbonyl hydrazone derivatives, a nitro group introduced at C5 position of 1 was necessary for obtaining the potent compound as nematicidal agents. These preliminary results will pave the way for further modification of paeonol in the development of potential new nematicides.

Roots effect is not generally considered in studies assessing the performance of crops in response to green manuring. However, such effect can contribute to a better understanding of crop rotation. The aim of this study was to assess the effect of root and shoot of two legumes on the production of cabbage. The experiment was conducted in pots of 10 liters containing substrate of 2:1 soil/sand. The experiment was arranged in a factorial scheme (2x3 + 2) in a randomized block design with five replicates using two legume species (Crotalaria juncea L. and Canavalia ensiformis L), three plant parts (root, shoot, or whole plant), and two additional treatments (mineral fertilization with 100% and 50% of the recommended dose of N for growing cabbage). Pots with legume treatments received mineral fertilizer with 50% of the recommended dose of N for growing cabbage. The experimental plot consisted of a pot containing one plant of cabbage. Legumes were grown in pots and harvested at 78 days. The root biomass was determined in extra pots. Production was assessed using head fresh and dry weight. The application of the whole plant of both legume species reduced cabbage production. However, root or shoot of both legume species was equivalent to 50% of mineral N fertilization required for the cultivation of cabbage.

Phytotoxic effects of invasive weed Parthenium hysterophorus were studied by using whole plant, leaf and root aqueous extracts at 0, 2.5, 5.0, 7.5 and 10% (w/v) concentrations against germination and early seedling growth of wheat and canola. Studies were carried out both in Petri plates with filter paper as substratum placed in controlled conditions and soil-filled plastic pots placed in open environments. Pronounced variation was noted for phytotoxic activity of different plant parts of parthenium, aqueous extract concentrations, test species, and bioassay techniques. Aqueous parthenium extracts either inhibited or delayed the germination and suppressed seedling growth of test species over control. For both test species, all the germination attributes were suppressed to a greater extent in Petri plates than in plastic pots. Leaf extracts were more suppressive to germination of test species than whole plant and root extracts. Increasing extract concentration beyond 2.5% caused significant reduction in seedling dry biomass of both test species. Aqueous parthenium extract diminished chlorophyll contents of wheat and canola by 32-63% and 29 69%, respectively. Nevertheless, an increase of 9-172% and 22-60% in phenolic contents of wheat and canola was recorded. Canola appeared to be more susceptible than wheat at all extract concentrations. Present study concluded that bioassays conducted under controlled condition using filter paper as substratum may be misleading due to over estimation of allelopathic response and variation in potential of receiver and donor species. Furthermore, it implies that threshold concentrations of allelochemicals for test species in Petri plates are rarely reached under field conditions.
