The synthesis of a proline-rich cyclic heptapeptide, fanlizhicyclopeptide A (8), previouslyisolated from the fruits of Annona squamosa (sugar-apples), is described via coupling oftetrapeptide l-prolyl-l-tyrosyl-l-leucyl-l-proline methyl ester with tripeptide Boc-glycyl-lvalyl-l-proline followed by cyclization of the linear fragment having seven amino acid units.Structure of the synthesized cycl...

The aim of the present study was to evaluate the anthelmintic activity of ethanolic and aqueous extract of leaves and bark of Tamarindus indica Linn using Pheretima posthuma and Tubifex tubifex as test worms. The time of paralysis and time of death were studied and the activity was compared with piperazine citrate as reference standard. The alcohol and aqueous extract of bark of Tamarindus indi...

BACKGROUND Rubus fruticosus is used in tribal medicine as anthelmintic and an antispasmodic. In the current work, we investigated the anthelmintic and antispasmodic activities of crude methanol extract of fruits of R. fruticosus on scientific grounds. Acute toxicity and brine shrimp cytotoxicity activity of the extract were also performed. METHODS Acute toxicity study of crude methanol extrac...

Artocarpus lakoocha Roxb (Moraceae) is cultivated in Uttar Pradesh, Bengal, Khasi Hills and Western Ghats. Objectives of the present study were to determine antibacterial, antioxidant, anthelmintic and insecticidal efficacy of methanol extract of A. lakoocha fruit pericarp. Antibacterial activity was tested against by Agar well diffusion method. Antioxidant activity in terms of free radical sca...

The anthelmintic activity of the Imethanolic extract of the root bark of Carissa carandas was evaluated on adult Indian earthworm (Pheretima posthuma) using albendazole as a reference standard. The extract caused paralysis followed by the death of worm at the tested dose level. The extract at the highest tested concentration has anthelmintic activity comparable with that of standard drug albend...

Background: The plant Gmelina arborea has been traditionally used in India for several medicinal purposes like anthelmintic, diuretic, anti-inflammatory, antibacterial and antidiabetic. Aims: The aim of the present study is to explore the anthelmintic and antidiabetic activities of G. arborea bark extracts using ethanol, ethyl acetate, n-butanol and petroleum ether as solvents. Material and met...

We measured in vitro anthelmintic activity in extracts from 85 species of Australian native shrub, with a view to identifying species able to provide a degree of worm control in grazing systems. Approximately 40% of the species showed significant activity in inhibiting development of Haemonchus contortus larvae. The most active extracts showed IC50 values of 60-300 microg/ml. Pre-incubation wit...

Combretum mucronatum Schumach. & Thonn. is a medicinal plant widely used in West African traditional medicine for wound healing and the treatment of helminth infections. The present study aimed at a phytochemical characterization of a hydroalcoholic leaf extract of this plant and the identification of the anthelmintic compounds by bioassay-guided fractionation. An EtOH-H2O (1:1) extract...

BACKGROUND Leaves of Caesalpinia bonducella (L.) Roxb. have been traditionally used as an herbal remedy to treat the intestinal helminthic infections in traditional medicine of India. AIM This study was undertaken to evaluate the potential in vitro and in vivo anthelmintic effects of C. bonducella leaf extract against Syphacia obvelata (Nematoda) and Hymenolepis diminuta (Cestoda). MATERIAL...

Present study was carried out to investigate the anthelmintic potential of petroleum-ether extract of Portulaca oleracea against Pheretima posthuma as a species of earthworm. Various concentrations (25‐100 mg/ml) of petroleum-ether extract were evaluated for anthelmintic activity by recording the time required for paralysis and death of worms. Albendazole was used as standard. Result indicates ...
