Abstract: The present paper deals with the phytochemical screening of therapeutic importance from Strychnos potatorum L.f., an important medicinal plant. This study involves the preliminary screening, quantitative determination and the qualitative thin layer chromatographic separation of secondary metabolites from the root, stem bark and seeds (collected and market) of S.potatorum. Further, HPLC alkaloid profile of the seed has been studied. The generated data has provided the basis for its wide use as the therapeutant both in the traditional and folk medicines.

TL;DR: These natural coagulants produce a 'low risk' water; however, additional disinfection or boiling should be practised during localised outbreaks/epidemics of enteric infections.
Abstract: Seeds of the plant species Strychnos potatorum and Moringa oleifera contain natural polyelectrolytes which can be used as coagulants to clarify turbid waters. In laboratory tests, direct filtration of a turbid surface water (turbidity 15-25 NTU, heterotrophic bacteria 280-500 cfu ml(-1), and fecal coliforms 280-500 MPN 100 ml(-1)), with seeds of S. potatorum or M. oleifera as coagulant, produced a substantial improvement in its aesthetic and microbiological quality (turbidity 0.3-1.5 NTU, heterotrophic bacteria 5-20 cfu ml(-1) and fecal coliforms 5-10 MPN 100 ml(-1)). The method appears suitable for home water treatment in rural areas of developing countries. These natural coagulants produce a 'low risk' water; however, additional disinfection or boiling should be practised during localised outbreaks/epidemics of enteric infections.

Abstract: The ability of three plant materials, seeds such as Moringa oleifera , Strychnos potatorum and Phaseolus vulgaris , to act as natural coagulants was tested using synthetic turbid water formulated to resemble the drinking water. An improved and alternative method for the extraction of the active coagulant agent M. oleifera , S. potatorum , P. vulgaris seeds was developed and compared with the conventional water extraction method. In the new method the seeds were extracted using different solvents of NaCl and NaOH to extract the active coagulant agent from natural coagulants. In addition, ultrasound was investigated as a potential method to assist the extraction process. Batch coagulation experiments were conducted to evaluate the performance of the extracted coagulant achieved through various schemes. The optimum turbidity removal at different values of initial synthetic wastewater turbidity from 100 to 500 NTU was investigated. Sodium chloride at 0.5 M was found to provide a high turbidity removal of >99% compared to NaOH and distilled water extract. Among these three coagulant M. oleifera seed extracts is the highest performance in turbidity removal. The optimum coagulant dosage showed the coagulation with blended coagulant M. oleifera , S. potatorum and P. vulgaris . The study was carried out for initial turbidity of the sample such as 100 NTU (low), 250 NTU (medium) and 500 NTU (high). For the natural coagulant dosage was found to be 250–1000 mg/L respectively. It was found that the percentage of removal is highest in M. oleifera .

TL;DR: Reduced enzymic and nonenzymic antioxidant levels and elevated lipid peroxide levels were restored to normal by administration of SPP and SPE, and Histopathological studies further confirmed the hepatoprotective activity of SPE when compared with the CCl4 treated control groups.
Abstract: Strychnos potatorum Linn. seeds are used in the Indian traditional system of medicine for the treatment of hepatopathy, nephropathy, gonorrhoea, leucorrhoea, gastropathy, bronchitis, chronic diarrhoea, strangury, renal and vesicle calculi, diabetes and eye diseases. The present study describes the hepatoprotective and antioxidant activities of the seed powder (SPP) and aqueous extract (SPE) of Strychnos potatorum seeds against CCl4-induced acute hepatic injury. Hepatic injury was achieved by injecting 3 ml/kg, s.c. of CCl4 in equal proportion with olive oil. Both SPP and SPE at the doses 100 and 200 mg/kg, p.o. offered significant (p < 0.001) hepatoprotective action by reducing the serum marker enzymes like serum glutamate oxaloacetate transaminase (SGOT) and serum glutamate pyruvate transaminase (SGPT). They also reduced the elevated levels of ALP and serum bilirubin. Reduced enzymic and nonenzymic antioxidant levels and elevated lipid peroxide levels were restored to normal by administration of SPP and SPE. Histopathological studies further confirmed the hepatoprotective activity of SPP and SPE when compared with the CCl4 treated control groups. The results obtained were compared with Silymarin (50 mg/kg, p.o.), the standard drug. In conclusion, SPE (200 mg/kg, p.o.) showed significant hepatoprotective activity similar to that of the standard drug, Silymarin (50 mg/kg, p.o.).

TL;DR: SPP and SPE showed reduction in rat paw edema volume and it could significantly normalize the haematological and biochemical abnormalities in adjuvant induced arthritic rats in both developing and developed phases of FCA induced arthritis.
Abstract: Strychnos potatorum Linn (Loganiaceae) is a moderate sized tree found in southern and central parts of India, Sri Lanka and Burma. In traditional system of medicine, Strychnos potatorum Linn seeds were used for various ailments including inflammation, diabetes etc. To investigate the folkloric use of the seeds the present study was carried out on Freund's adjuvant induced arthritic rats. The present study states the effect of the aqueous extract (SPE) and the whole seed powder (SPP) of Strychnos potatorum Linn seeds on the Freund's complete adjuvant (FCA) induced arthritic rat paw edema, body weight changes and alterations in haematological and biochemical parameters in both developing and developed phases of arthritis. Histopathology of proximal interphalangeal joints and radiology of hind legs were studied. In FCA induced arthritic rats, there was significant increase in rat paw volume and decrease in body weight increment, whereas SPP and SPE treated groups, showed significant reduction in paw volume and normal gain in body weight. The altered haematological parameters (Hb, RBC, WBC and ESR) and biochemical parameters (blood urea, serum creatinine, total proteins and acute phase proteins) in the arthritic rats were significantly brought back to near normal by the SPP and SPE treatment at the dose of 200 mg/kg/p.o in both developing and developed phases of arthritis. Further the histopathological and radiological studies revealed the antiarthritic activity of SPP and SPE by indicating fewer abnormalities in these groups when compared to the arthritic control group. In conclusion, both SPP and SPE at the specified dose level of 200 mg/kg, p.o. showed reduction in rat paw edema volume and it could significantly normalize the haematological and biochemical abnormalities in adjuvant induced arthritic rats in both developing and developed phases of FCA induced arthritis. Further the histopathological and radiological studies confirmed the antiarthritic activity of SPP and SPE.
