Objectives:Ethanol extract of the stem of Bauhinia purpurea Linn. was subjected to analgesic and anti-inflammatory activities in animal models.Materials and Methods:Albino Wistar rats and mice were the experimental animals respectively. Different CNS depressant paradigms like analgesic activity (determined by Eddy's hot plate method and acetic acid writhing method) and anti-inflammatory activity determined by carrageenan induced paw edema using plethysmometer in albino rats) were carried out, following the intra-peritoneal administration of ethanol extract of Bauhinia purpurea Linn. (BP) at the dose level of 50 mg/kg and 100 mg/kg.Results:The analgesic and anti-inflammatory activities of ethanol extracts of BP were significant (P < 0.001). The maximum analgesic effect was observed at 120 min at the dose of 100 mg/kg (i.p.) and was comparable to that of standard analgin (150 mg/kg) and the percentage of edema inhibition effect was 46.4% and 77% for 50 mg/kg and 100 mg/kg (i.p) respectively. Anti-inflammatory activity was compared with standard Diclofenac sodium (5 mg/kg).Conclusion:Ethanol extract of Bauhinia purpurea has shown significant analgesic and anti-inflammatory activities at the dose of 100 mg/kg and was comparable with corresponding standard drugs. The activity was attributed to the presence of phytoconstituents in the tested extract.

Antioxidant constituents from natural resources possess multifacetedness in their multitude and magnitude of activity and provide enormous scope in correcting imbalance. [4-6] "Sitopaladi churna" (SPC) is a polyherbal Ayurvedic medicine prescribed for pleurodynia, intercostal neuralgia, cold, cough associated with bronchitis, pneumonia, tuberculosis, burning sensation in extremities, supportive agent for allergy, viral respiratory infection, digestive impairment and in pharyngeal and chest congestion. The ingredients present in Sitopaladi churna have been reported to possess antioxidant activity. [7-9] But there is no scientific proof to support antioxidant potential of Sitopaladi churna. The present study therefore carried out to investigate the antioxidant potential of aqueous and methanolic extract of Sitopaladi churna.
Terminalia tomentosa bark belongs to the family Combretaceae. The plant bark is astringent and useful in the treatment of ulcers, vata, fractures, hemorrhages, bronchitis, and diarrhea. Phytochemical investigation of T. tomentosa bark confirms the presence of flavonoids, polyphenols, and tannins. The plant has not been investigated for its anti-inflammatory and antiarthritic activity. The present study was undertaken to explore its possible anti-inflammatory and antiarthritic activity. Anti-inflammatory activity of alcoholic and aqueous extracts of the bark was assessed by in vivo methods. In vivo antiarthritic potential of the extracts was evaluated by Complete Freund's Adjuvant (CFA) induced arthritis in Wistar rats. Our findings showed that the alcoholic and aqueous extracts exhibited anti-inflammatory activity at 500 mg/kg oral dose in carrageenan-induced hind paw edema and carrageenan-induced air pouch inflammation models. We also found alcoholic as well as aqueous extracts of the bark restored the altered blood and serum parameters caused by the Complete Freund's Adjuvant-induced arthritis in Wistar rats. This study shows that the T. tomentosa bark extracts possess anti-inflammatory activity and have pronounced effects on adjuvant arthritis also. Future studies are necessary to provide deeper insight into the exact mechanism of the action of anti-inflammatory and antiarthritic activity of T. tomentosa.
Background: Homonoia riparia Lour. (Family: Euphorbiaceae) is an important medicinal plant in Indian and Chinese systems of medicine used in the treatment of various medical conditions like urolithiasis, renal problems, and inflammation. This is the first report on the pharmacognostical standardisation and phytochemical evaluation of whole plant of Homonoia riparia Lour. Objective: To establish the pharmacognostical and physicochemical standardisation parameters of whole plant of Homonoia riparia Lour. Materials and Methods: The plant was studied for the morpho-anatomical characters, standardisation parameters such as ash value, extractive value, fluorescence analysis, loss on drying, swelling index, foaming index according to Indian Pharmacopoeia and WHO guidelines. Phytochemical analysis was also performed by standard methods. Quantification of gallic acid in Homonoia riparia was carried out using HPTLC technique. Results: The detailed microscopy of root revealed the presence of cork, cork cambium, pericyclic fibres, thick walled parenchyma and starch granules. The distinguishing characters of stem are presence of sclereids, xylem, phloem, fibres. Leaf microscopy showed the presence of anomocytic stomata, bicollateral vascular bundles ensheathed by fibres. Rosette crystals are present in all the parts of the plant. Starch grains are abundantly present in root and stem but absent in leaves. Various physicochemical parameters were also determined. Phytochemical screening of the extract and HPTLC quantification of gallic acid was also performed. Conclusion: The present study provides pharmacognostical, physicochemical and phytochemical details of the whole plant of Homonoia riparia which are useful in laying down standardization and pharmacopoeia parameters.
Background:Macrosolen parasiticus (L.) Danser belonging to Loranthaceaea (mistletoe family) is a parasitic plant that grows on different host plants such as mango, jack fruit, peepal, neem tree, etc., This study was aimed to investigate the anti-cancer activity of methanolic and aqueous extract of stem of M. parasiticus.Objectives:To investigate the in vitro cytotoxic potential of the methanolic and aqueous extracts from stems of M. parasiticus against MCF-7 breast cancer cells by brine shrimp lethality (BSL) bioassay, MTT assay and sulforhodamine B (SRB) assay.Materials and Methods:The extracts were tested in human breast cancer cell lines in vitro for percentage cytotoxicity, apoptosis by acridine orange/ethidium bromide staining, LD50 and IC50 values after treatment with M. parasiticus extracts.Results:In BSL bioassay, aqueous extract showed more significant (P < 0.01) cytotoxicity with LD50 82.79 ± 2.67 μg/mL as compared to methanolic extract with LD50 125 ± 3.04 μg/mL. The methanolic extract of M. parasiticus showed IC50 97.33 ± 3.75 μg/mL (MTT) (P < 0.05) and 94.58 ± 3.84 μg/mL (SRB) (P < 0.01) assays against MCF-7. The aqueous extract of M. parasiticus demonstrated higher activity with IC50 59.33 ± 3.3 μg/mL (MTT) (P < 0.01) and 51.9 ± 1.87 μg/mL (SRB)(P < 0.01) assays, after 48 h of exposure and thus showed significant dose-dependent cytotoxic activity.Conclusion:The finding demonstrated that both extracts of M. parasiticus showed significant cytotoxic activity, however aqueous extract demonstrated higher activity against MCF-7 breast cancer cells.
Objective: The aim of the study was to evaluate whether Vernonia cinerea (VC) regenerates the proximal renal tubular cells in cisplatin-induced necrosis in male Swiss albino mice.Methods: The crude aqueous extract (CAE) of VC was fractionated from non-polar to polar using different solvents. Mice were injected a single dose of cisplatin (15 mg/kg) on day 1, which took 5 days to cause maximal renal damage. From day 6, CAE and all fractions were orally administered (200, 300, and 400 mg/kg) for 5 continuous days. On day 11, blood was collected to estimate urea and creatinine. Kidney was collected for histology and grading was done.Results: Cisplatin induced proximal renal tubular damage (grade 5) in corticomedullary junction, characterized by necrosis, proximal tubular dilatation, inflammation and vasodilation. Aqueous fraction (AF) did not show any regeneration; whereas, 400 mg/kg dose of CAE and butanol fraction (BF) showed a significant reduction (p<0.001) in proximal tubular damage (Grade 3) and 50–75% regeneration of proximal tubular epithelial cells.Conclusion: This is the first study to demonstrate the regenerative potential of Neichitti kashayam (CAE of VC) and its BF in cisplatin-induced proximal tubular damage in kidney. Further study is warranted to find out the dose regimen for complete regeneration, lead compounds, and molecular mechanism.
Standardization of herbal formulations is essential in order to assess the quality of drugs, based on the concentration of their active principles. This article reports on standardization of Ajmodadi churna, a polyherbal ayurvedic medicine used as a carminative and an antispasmodic, and is a strong wormifuge, and helps in all painful conditions like sciatica and stiffness in back and also restores normal digestive functions. Ajmodadi churna was prepared as per Ayurvedic Formulary of India. In-house preparation and the marketed drug have been standardized on the basis of organoleptic characters, physical characteristics, and physico-chemical properties. The set parameters were found to be sufficient to evaluate the churna and can be used as reference standards for the quality control/quality assurance laboratory of a Pharmaceutical house.
