In the present study, the petroleum ether and alcoholic extract of Morinda citrifolia L. (Noni) leaves were subjected to preliminary screening for antimicrobial and anthelmintic activity. The alcoholic extract exhibited significant anti bacterial, antifungal activity, comparable to the standard drug tetracycline. The petroleum ether and alcoholic extract were evaluated for Anthelmintic activity...

The ethanolic extract of the plant Pistia stratiotes (Araceae) was investigated for activity against Indian earthworms Pheretima posthuma and nematode Ascardi galli. Various concentrations (10, 20, 50 mg/ml) of ethanolic extract were tested, which involved determination of time of paralysis and time of death of the worms. It was compared with Piperazine citrate (15 mg/ml) and Albendazole (20 mg...

Two kinds of amphoteric glycosphingolipid analogues from the earthworm Pheretima hilgendorfi were synthesized as follows: The key reaction is a coupling of a phosphocholine group at the position C-6 of 1 and 6 which was attempted using 2-chloro-2-oxo-1,3,2-dioxaphospholane, followed by reaction of the resulting cyclic phosphate intermediate with anhydrous trimethylamine to give 2 and 7. Subsequ...

Two kinds of glycosphingolipid analogues from the earthworm Pheretima hilgendorfi were synthesized as follows: the trisaccharide 2-(tetradecyl)hexadecyl alpha-D-mannopyranosyl-(1-->4)-beta-D-galactopyranosyl-(1-->6)-beta-D- galactopyranoside (13) and the tetrasaccharide 2-(tetradecyl) hexadecyl alpha-D-galactopyranosyl-(1-->6)-[alpha-D-mannopyranosyl-(1-->4)]-beta-D - galactopyranosyl-(1-->6)-b...

Tephrosia purpurea is a copiously branched herbaceous perennial plant distributed throughout the tropics which is used in the treatment of bronchitis, diuretic, pimples, tonic, laxative, cough, and tumour. The present study is an attempt to explore the anthelmintic activity of aqueous and methanolic extract of leaves of plant Tephrosia purpurea . The various concentrations of aqueous and methan...

Since Bhat and Barker (1948) reviewed the existing literature and reported on the isolation and characteristics of an oxalate-decomposing Vibrio, only two attempts appear to have been made to study the problem of oxalate decomposition by microorganisms. One of the studied reported (Janota, 1950) relates to the utilization of oxalate by Psudomonas extorquens Basalik, whereas the other by Muiller...

The Pheretima complex within the Megascolecidae family is a major earthworm group. Recently, the systematic status of the Pheretima complex based on morphology was challenged by molecular studies. In this study, we carry out the first comparative mitogenomic study in oligochaetes. The mitogenomes of 15 earthworm species were sequenced and compared with other 9 available earthworm mitogenomes, w...
