Anti-ulcer activity of the Solanum nigrum L. extracts was studied in rats by using pylorus ligated ulcer model. Rantidine was used as the standard drug for comparison. The animals were sacrificed after 19 hrs after the ligation. Stomach was dissected out and contents were drained into tubes and were centrifuged at 1000 rpm for 10min and volume was noted. The PH of gastric juice was recorded using a PH meter. The contents were subjected for analysis of free and total acidity. The numbers of ulcers per stomach was noted and severity of ulcers scored. Then the blood samples were collected and subjected to estimation of serum calcium and alkaline phosphatase level. The results revealed that 200 and 400mg/kg dosages of Solanum leaf extracts showed significantly comparable anti ulcer-activity as that of Rantidine, showing an anti-ulcer activity of the extracts. Thus Solanum nigrum leaves may reduce the acidity of the gastric juice and also prevent the mucosal damage and ulcer...

The aim of present study was to determine whether pharmaceutical and pharmacological activity of aspirin would enhance in form of inclusion complex with β–cyclodextrin or not.Aspirin (Acetyl salicylic acid) a non steroidal anti-inflammatory drug, was formulated in to inclusion complex with β–cyclodextrin (β–CD) by solvent evaporation. The phase-solubility curve was AL type and Kst was found to be 127.8 M-1. FT-IR and microscopic examinatinos were revealed confirmation of inclusion formation. Solubility and permeability of aspirin was enhanced in presence of β–CD. Similarly the pharmacological activity i.e. analgesic and anti-inflammatory activity were also enhanced in presence of β –...

The scientific basis of medicinal plants often claimed that the valuable ethnobotanical medicinal-related information was true. Hence, researchers always develop deep interest in finding natural resources like medicinal plants to combat infectious diseases instead of using modern pharmaceutical drugs that can lead to vast antibiotic resistance issues. In this present study, various leaf extracts of Persicaria chinensis (L.) H. Grosswere investigated for their antibacterial and antifungal activities against various Gram-positive and Gram-negative bacteria and fungi by disc diffusion method. The aqueous, chloroform, methanol, and petroleum ether extracts of P. chinensis leaves were prepared by cold maceration technique and preliminary phyto-constituent investigation was carried out on the extracts. The antibacterial and antifungal activities were assessed by measuring the diameter of the zone of inhibition, and the results were compared with standard antibiotics, amoxicillin and fluconazole respectively. All leaf extracts possessed antibacterial and antifungal activity against the selected pathogenic bacteria and fungi. Nevertheless, methanol and aqueous extracts and reference drugs (amoxicillin and fluconazole) showed comparable efficacy in inhibiting certain microbial growths....

This paper deals with the significance and importance of medicinal plants.New flavone glycoside A, m.p. 222-224oC, m.f. C34H42O20, [M+] 770 (FABMS) has been isolated from the stems of Sesbania aculeata Pers. along with three known compounds Kaempferol 3-O-a-L-rhamnopyranosyl-(1®2)-b-D-glucopyranoside, (B) and Mearnsetin-3-O-a-L-rhamnopyranoside (C) Gehuain(isoflavone) (D). The compound A was characterized as 5, 7, 8-trihydroxy-6, 4’-dimethoxy flavone-7-O-a-L-rhamnopyranosyl-1®4)-O-b-D-xylopyranosyl-(1®4)-galactopyranoside by various chemical degradations and spectral analysis. Compound was subjected to antioxidant, antibacterial activity. Compound A showed potent antioxidant activity, of which the methanol and chloroform fraction demonstrated the strongest. Antioxidant activity with the IC50 value of 52.40 μg/ml and 60.15 μg/ml,...

Methanolic extracts of two Indian medicinal plants Juniperus communis and Solanum xanthocarpum, were examined for their antimicrobial potential against selected bacteria and fungi. The purpose of screening is to justify and authenticate the use of Indian medicinal plants in ethno medicinal or folklore as traditional treasure to cure various ailments. In present investigations attempts were made to screen the Indian medicinal plants as antimicrobial agent. The extracts were tested against selected test bacteria and fungi through disc diffusion assay where Tetracycline and Mycostatin were used as standard. Indian medicinal plants have a traditional background that they have potentials to use as antimicrobial agents. The results showed that alcoholic extract possess excellent antimicrobial activity against selected test bacteria and fungi. The present results therefore offer a scientific basis for traditional use of the various extracts of Juniperus communis and Solanum...
