Acalypha indica Linn. also known as Acalypha spicata, A. ciliata, Indian Acalypha, belonging to family euphorbiaceae, is an erect annual herb occurring in waste places and along the road sides through out plains of India, ascending hills in Orissa1.
Leaves and twings contain alkaloids like acalyphine, acalyphamide, amides, quinine, sterols and cyanogenic glycosides. Plant contains kaemperol, sitosterol, triacetonamine2, and New amides like auranthiamide and its acetate succinimide, 2-methylanthraquinone, tri-o-methylellagic acidwere isolated from leaves of Acalypha indica Linn3.
The extract of whole plant was reported for post coital antifertility activity4, The aqeous extract of Acalypha indica Linn. shown neuroprotection and neurotherapy effect5, extract of leaves has shown antibacterial activity6 and anti-inflammatory activity7, Different extracts of Acalypha indica Linn. shown Larvicidal and ovicidal activity against Anapheles stephensi8, Antibacterial activity of biosythesized silver nanoparticles from Acalypha indica Linn. has been reported9.
In folk medicine leaves are known to be used in treatment of in ringworm infection rheumatoid arthritis, scabies, snake bite10, Root & leaves used in treatment of skin diseases, constipation, ulcer, bronchitis11.
Although various studies have been carried out with respect to plant parts for phytochemical and pharmacological activity but not much data is available to establish certain traditional uses mentioned for Acalypha indica Linn.
So based on existing phytochemical data & folklore medicine the present studies have been taken up to establish/provide scientific data for antioxidant & anthelmintic activity of leaf. There fore in present studies it is proposed to isolate the chemical constituents from leaves of Acalypha indica Linn. & to carry out in vitro antioxidant & in-vivo anthelmintic activity.
6.2-Review of Literature:
Four different extracts of whole plant of Acalypha indica Linn. were tested for post-coital antifertility activity in female albino rats. Of these, only petroleum ether and ethanol extracts were found most significant activity. But activity is reversible on withdrawal of extract4.
Aqueous extract of Acalypha indica Linn. were studied for Neuro- protection and neuro-therapy effect ex vivo on musculus gastrocnemius frog. Studies were done on two groups of frog, the parameters measured in this study are electrical activities such as amount and duration (in second) of repolarization, depolarization, resting potential, and height of spike after electrical stimulation. Extract showed both activities5.
Different extracts of leaves of Acalypha indica Linn. were evaluated for antibacterial activity against both gram positive and gram-negative bacteria. All extracts shown activity against various strains of gram positive and in gram negative only on Pseudomonas aeruginosa6.
Fresh juice of Acalypha indica Linn. leaf were evaluated for anti-inflammatory activity on four groups of albino rats which are pretreated orally with control, standard, (indomethacin), in combination of Both Acalypha indica & Indomethacin, Acalypha indica juice was effective in inhibition of paw Volume and oedema7.
Different leaf extract of Acalypha indica Linn. were tested for larvicidal, ovicidal, and oviposition attractancy against Anapheles stephensi. Hatchability of ovicidal activity was observed, the percent hatchability was inversely proporitional to concentration of extract and directly proportional to the eggs. Result of extracts having promising activity8.
Silver nanoparticles were rapidly synthesized using leaf extract of Acalypha Indica Linn. The antibacterial activity of synthesized silver nanoparticles showed effective inhibitory activity against water borne pathogens Viz., Escherichia Coli and Vibrio cholerae9.
6.3 - Objective of the Study: Collection of drug i.e. (leaf of Acalypha indica) and preparation of the extract of the drug (maceration / soxhlet) and Isolation of phytoconstituents from the extract, based on phytochemical screening by column chromatography/seperation method. Identification of isolated phytoconstituents by UV, IR, and NMR spectroscopy. Different extracts / isolated compounds would be studied for in vitro antioxidant activity by DPPH & superoxide radical method12. And in-vivo anthelmintic activity by using earth worm Pherentima posthuma13.
Materials and Methods:
