TL;DR: In this article, the suitability of Strychnos potatorum seed flakes (SPSF) on effective removal of diazinon residues in water was investigated.
Abstract: Objectives: Contamination of pesticide residues due to agricultural activities is a major concern of aquatic pollution and most of the agriculture based rural communities in developing countries are still consuming water from those contaminated water bodies. Therefore, development of readily available user-friendly low cost pesticide contaminant removal methods is still in need for above communities. In this study the suitability of Strychnos potatorum seed flakes (SPSF) on effective removal of diazinon residues in water was investigated. Methods: SPSF was prepared and characterized using SEM and FTIR analysis. Batch adsorption studies, isotherm studies and thermodynamic studies were carried out to determine the removal efficiency of diazinon by SPSF. Findings: The maximum removal of diazinon residues (75.9%) was obtained within 10 min at pH 6. Therefore, SPSF are efficient adsorbent for diazinon removal due to fast and efficient removal of diazinon at ambient conditions. The removal of diazinon residues by SPSF was expressed with Langmuir isotherm model. The maximum adsorption capacity of SPSF, obtained from Langmuir isotherm for diazinon adsorption was found to be 2.5mg/g. Thermodynamic studies revealed that the removal of diazinon by the SPSF was spontaneous and exothermic at relatively low temperatures. Novelty: The SPSF adsorbent is a naturally available cost effective and ecofriendly adsorbent which has not been extensively studied for the removal of frequently used pesticides such as diazinon. The findings of the study revealed that the SPSF adsorbent can be considered as a promising remedy for house hold purification of diazinon contaminated waters.

TL;DR: In this article, the effect of bed height, flow rate, and initial concentration of PIE in terms of color removal efficiency was evaluated in a fixed-bed adsorption column (FBC) for water-based paint industry effluent.
Abstract: The study was focused on, to make use of the agro-based material Strychnos potatorum as an adsorbent, for the treatment of simulated water-based paint industry effluent (PIE) in a fixed-bed adsorption column (FBC). The influence of bed height, flow rate, and initial concentration of PIE were evaluated in terms of color removal efficiency. The highest color removal was achieved at a larger breakthrough time, and lengthier mass transfer zone was viewed at the lowest flow rate, lowest initial concentration, and highest bed height used in this study. For a successful design of a FBC, breakthrough curves were made and the experimental data were fitted using well-established models such as: Thomas/Bed depth service time (BDST), Adams–Bohart, Yoon–Nelson, and Wang. From the plot of these models, parameters like adsorption capacity and rate constants were calculated. Mass transfer models like Weber–Morris, Boyd, Urano–Tachkawa, and Mathews–Weber were applied to identify the rate-limiting step of the overa...

TL;DR: A protocol for germination of Strychnos potatorum using zygotic embryo culture as an embryo rescue method will be useful to overcome seed dormancy and for rapid multiplication and conservation of S. Potatorum.
Abstract: The present study reports a protocol for germination of Strychnos potatorum (ver. Tel. Chilla) using zygotic embryo culture as an embryo rescue method. A 100% germination rate was obtained by culturing the embryos on full-strength Murashige and Skoog’s medium (MS) containing 20 g/L sucrose in comparison to McCown and Lloyd’s Woody Plant Medium (WPM). Germination rates decreased when the sucrose concentration was lower or higher than 20 g·L−1. WPM/MS medium containing glucose at levels 30, 20, 15 g·L−1 showed a smaller percentage of germination and at quarter strength, WPM/MS medium with glucose did not respond. Multiple shoot formation was found at 1.0–2.0 mg/L BAP; 3.0 mg/L Kn; 2.0 mg/L TDZ on MS medium with 20 g·L−1 sucrose. Germination rates improved when the embryos were placed upright (vertically) in the medium. The in vitro germinated seedlings were acclimatized in a walk-in-chamber and maintained in the green house with the survival rate of 65%–75%. These plants were transferred to the field and were found to be phenotypically normal, healthy and similar to donor plants. This protocol will be useful to overcome seed dormancy and for rapid multiplication and conservation of S. potatorum using zygotic embryo culture.

TL;DR: The results reveal that, the drug treatment decreased the LPO levels in plasma and tissues, either by interception of the formation or by scavenging the active oxygen species, and SPE was found to show higher antioxidant activity when compared with SPP.
Abstract: The Indian system of medicine provides Strychnos potatorum Linn. seeds for the treatment of various ailments like jaundice, bronchitis, diabetes, renal and vesicle calculi, conjunctivitis, chronic diarrhoea, dysentery etc. The present study involves the effect of crude powder (SPP) and aqueous extract (SPE) of S. potatorum Linn seeds on in vivo antioxidant defense system against Freund’s complete adjuvant (FCA) induced arthritis in rats at the dose of 200 mg/kg/p.o for 14 and 28 days and in vitro antioxidant activity against Ferrous thiocyanate (FTC) and Thiobarbiturate (TBA) induced lipid peroxidation. The antioxidant defense system parameters studied in plasma and tissues of arthritic rats were found to be altered significantly. These alterations observed in arthritic rats may be due to the increased oxidative stress in the tissues, which were significantly reduced in SPP and SPE treated arthritic rats. The results reveal that, the drug treatment decreased the LPO levels in plasma and tissues, either by interception of the formation or by scavenging the active oxygen species. The raise in enzymic and nonenzymic antioxidants level may be due to the sparing effect of antioxidant defense system as the drugs SPP and SPE have scavenged the free radicals by various antioxidant phytochemicals like steroids, triterpenes and polyphenolics present in it either by individual or by combined action. In in vitro total antioxidant analysis by FTC and TBA methods, SPE was found to show higher antioxidant activity when compared with SPP. Key words: Strychnos potatorum, enzymic and non-enzymic antioxidants, free radical scavenging, lipid peroxidation.
