Pheretima (family Megascolecidae) has been documented as a potent agent for the treatment of cough and breathing difficulty in traditional Chinese medicine for nearly 2000 years. The water extract of Pheretima was separated into three fractions of the ethanolic precipitate, the alkaline fraction and the acidic fraction. Among the three fractions, the acidic fraction showed the most potent spasm...

Petroleum ether (60-80°C), chloroform, ethyl acetate, ethanol and aqueous extract of aerial parts of Melothria heterophylla Lour. were evaluated separately for anthelmintic activity on adult Indian earthworms (Pheretima posthuma), using albandazole and piperazine citrate as reference standards. The results indicated that the ethanol extract of M. heterophylla Lour (EEMH) was more potent than th...

Ethanolic and Chloroform extract of leaves of Justicia beddomei were evaluated separately for anthelmintic activity on adult Indian earthworms Pheretima posthuma, using Piperazine citrate as reference standard. The results indicated that ethanolic extract was more potent than the chloroform extract.

Three types of glycoclusters related to an amphoteric glycosphingolipid found in the earthworm Pheretima hilgendorfi were synthesized. The glycoclusters were prepared from a common precursor and a simple approach for the rational design of a glycocluster was developed.

New species of ciliates belong to genus Metaradiophrya was recorded from intestine of Pheretima elongata, collected from Aurangabad district (M.S.). In the present study, morphological characteristics of this ciliate and its similarities and differences were discussed compared with other species of this genus.

The lipid composition of the earthworm, Pheretima asiatica (Annelida), was analyzed. Four glycerophospholipids, together with four known glycosphingolipids, were isolated in pure form. The former four were 1-alkyl 2-acyl glycerophosphocholines possessing a C17:0 and/or C18:1 fatty acid residue. Their structures, including the position and geometry of the double bond, were determined on the base...

The aim of present study was to evaluate antihelmintic potential of crude extract of root of Butea monospermous using Pheretima posthuma as test worm. Butea monosperma is distributed all over India and has been used by triable as well a local people widely. Popularly known as 'dhak' or 'palas', commonly known as ‘Flame of forest’. It has been found to have antimicrobial, wound healing, antifung...

The silica skeleton of the deep-sea sponge Euplectella aspergillum was recently shown to be structured over at least six levels of hierarchy with a clear mechanical functionality. In particular, the skeleton is built of laminated spicules that consist of alternating layers of silica and organic material. In the present work, we investigated the micromechanical properties of the composite materi...

A series of sulfonamide derivatives HR1-HR5 were synthesized in one step reaction (nucleophilic substitution reaction SN2). Structures of new products were confirmed by elemental and spectral analysis i.e., FTIR, UV, 1H NMR, 13C NMR, EIS-MS. In-vitro, antibacterial and anti-fungal activity of newly synthesized compounds was investigated against two bacterial strains: Escherichia coli and Staphy...
