Abstract

The aqueous, methanol and chloroform extracts of Tridax procumbens Linn belonging to the family Asteraceae were evaluated for anthelmintic activity. The dried powder of whole plant of Tridax procumbens was extracted and the anthelmintic activity was studied. Aqueous, methanol and chloroform extracts collected were tested for anthelmintic activity against Indian adult earthworm Eisenia fetida and recorded the time taken for induction of paralysis and death. Two concentrations (50 mg/ml and 100 mg/ml) of aqueous, methanol and chloroform extract were evaluated in the bioassay involving determination of time of paralysis (P) and time of death (D) of the worms. Albendazole (100 mg/ml) was used as reference standard and normal saline solution as a control. Comparative results of present study indicated that the aqueous, methanol and chloroform whole plant extracts of Tridax procumbens Linn shows significantly dose depending pharmacological activity on the Indian earthworms.

Introduction

Helminths parasite infections are global problems with serious social and economic reverberation in the countries. The diseases affect the health status of a large fraction of the human population as well as in animals. To treat parasitic infections anthelmintics are used. Anthelmintics or antihelminthics are group of antiparasitic drugs that expel parasitic worms (helminthes) from body either by stunning or killing them without causing significant damage to the host. They may also be called vermifuges those that stun or vermicides (those that kill). They are used to treat people who are infected by helminthes, a condition called helminthiasis. This includes both flat worms, e.g., flukes and tapeworms and round worms, i.e., nematodes.

They are of immense importance for human tropical and veterinary medicine. Since this drugs used to treat the parasitic infections but they associated with numerous number of side effects hence, the discovery and development of new drugs derived from plant sources is required which cause less harm to human being and animals [1,2].

It is said that nature is enriched with uncountable number of medicinal resource. Long before the existence of medical facilities plant extracts were being used for human well being to prevent themselves from various chronic and infectious diseases. The new era of drug development process is searching for some natural compounds which have great medicinal value that’s why the demand of plant based therapeutics seems to be increasing in current scenario due to the growing recognition that they are natural products, having no or less side effects one of the plant that can be used as herbal medicine is Tridax procumbens. Commonly known as coat buttons or tridax daisy is a species of flowering plant in the Asteraceae family.

T.procumbens has diverse pharmacological properties such as immunomodulatory, anti oxidant, anti hepatotoxic, analgesic, anti diabetic, anti inflammatory, antifungal, and antimicrobial activities. The plant contains secondary metabolites such as flavonoids, alkaloids, tannins, carotenoids, saponins etc. The aim of this project is to evaluate the anthelmintic activity of whole plant extracts of Tridax procumbens L. as an alternative source of effective remedies for nematodiasis [3,4].

MATERIALS AND METHODS

Collection and authentication of plant

Fresh whole plant (leaves, stems, roots and flowers) of Tridax procumbens were collected from Thube farm Donwade, Dowade region of Bhagur in the month of February and authenticated by Ayurvedic doctor of S.M.B.T Ayurveda College and Hospital, Dhamangaon, Tal. Igatpuri, Dist. Nashik. After collection, dried leaves and other debries were removed. The plant washed under running tap water to remove soil. It was dried under shade for a period of 7 days and then pulverized in mechanical grinder to obtain coarse powder. The dried powder was stored in air tight bottles, and later subjected to extraction process (Figure 2) [8].

Extraction methodology

Aqueous extract

The coarse powdered material of Tridax procumbens (30 g) was subjected to soxhlet extraction with 450 ml of water as solvent for 6 hours and then filtered off. Following extraction process, the extract was concentrated on water bath until syrup consistency and then again evaporated to dryness.

Methanol extract

The coarse powdered material of Tridax procumbens (30 g) was subjected to soxhlet extraction with 450 ml of Methanol as solvent for 5 hours and then filtered off. Following extraction process, the extract was concentrated on water bath until syrup consistency and then again evaporated to dryness [9].

Chloroform extract

The coarse powdered material of Tridax procumbens (30 g) was subjected to soxhlet extraction with 450 ml of water as solvent for 4 hours and then filtered off. Following extraction process, the extract was concentrated on water bath until syrup consistency and then again evaporated to dryness [10].

Worms collection

Adult Indian earthworms, Eisenia fetida (Lumbricidae) were used to evaluate in vitro anthelmintic activity.

•Scientific name: Eisenia fetida

•Common name: Red worm, Tiger worm, Manure worm, Stink worm, Fish worm, striped worm etc.

•Habitat: Usually found in garden compost but also occurs in wet, decaying leaf litter, organic-rich soils and manure heaps

•Size: Typical size of adult is 6-9 cm.

•Collection: The earthworms were collected from vermicompost/Gandul khat, Adgaon, Nashik. They were washed with water and then by normal saline to remove soil.

The earthworms are 6-9 cm in length was used for the anthelmintic study. The earthworm resembles both anatomically and physiologically to the intestinal roundworms parasites of human being, hence can be used to study anthelmintic activity (Figure 3) [11].

Drugs and chemicals

Albendazole tablet IP (MANKIND PHARMA LTD) were used as reference drug and for control, normal saline solution (sodium chloride 0.9%w/v and dextrose 5% w/v injection IP) is used. The other chemical used are ethanol, methanol, and chloroform of analytical grade.

Phytochemical analysis

Phytochemical analysis of the extracts was performed according to standard procedures mentioned in trease and evans Pharmacognosy book.

Anthelmintic activity

In this the Indian adult earthworms (Eisenia fetida) of 6-9 cm length were used. The earthworms are divided into 8 groups, of 4 earthworms in each group. The aqueous, chloroform, and methanol (50,100 mg/ml, each) extracts was dissolved in normal saline solution and final volume was adjusted to 10 ml. similarly the reference drug solution of 10 mg/ml was prepared and adjusted to volume 10 ml. The extracts and standard drug solution were freshly prepared before starting the experiments. Take 8 petri plates, label each plate according to extract:

•Aqueous,

•Methanol,

•Chloroform,

•Standard

•For control.

The extracts of different concentration, Standard and control solutions were poured in respective labelled petri plate. All the earthworms first, washed by tap water than by normal saline solution before they released in to petri plate.

Observations, were made for the time taken to paralyze (paralysis was said to occur when earthworm didn’t revive in normal saline solution) and time of death (death was concluded when earthworms lost their motility and followed with their body color fading away). All the results were expressed as a mean ± SEM of 4 earthworms in each group (Figures 4 and 5).

CONCLUSION

On the basis of the results obtained at the end of the study we can conclude that the methanol and chloroform extract of Tridax procumbens Linn. Shows potent anthelmintic activity to that of standard anthelmintic drug i.e Albendazole.

Further studies using in vitro models are required to carry out and establish the effectiveness and pharmacological rationale for the use of Tridax procumbens Linn as an anthelmintic drug. The drug can be further explored for the isolation and characterization of the active constituents responsible for anthelmintic activity.
