Objective: The aim of this study was to investigate anthelmintic efficacy of D. regia and S. oleosa leaves. Material and methods: Firstly plant leaves material was defatted with petroleum ether and prepared hydro-alcoholic extracts. Hydroalcoholic extract taken and was evaluated separately for anthelmintic activity on adult Indian earthworm Pheretima posthuma, using Albendazole as reference standard, paralysis and death time was noted. Results and Conclusion: The results represented that the hydroalcoholic extract of D. regia was more potent than S. oleosa extract. Conclude that S. oleosa leaves could be used for development of novel anthemintic treatment.

Keywords: Plant extracts, anthelmintic, Pheretima posthuma, earthworm, Albendazole


Only a handful of anthelmintic compounds are currently available; these are classified into several families that such as benzimidazoles, macrocyclic lactones, imidazothiazoles, and cyclic Octadepsipeptides etc. Various studies recently have been showed the presence of gastrointestinal nematodes that are resistant to the main marketed available anthelmintic drugs on cattle farms. These drugs having various side effects, consequently, we believe the research of herbal plants species that could have antiparasitic activity, because many of these herbal plants have been used as traditional medicine in the olden days (Rajeshwari et al., 2014). Medicinal plants were the potent source of several pharmacological activities. Hence, the need for the investigation of the plants for the treatment has attained a great interest and in present investigation our objective was to investigate anthelmintic efficacy of D. regia and S. oleosa leaves.

Drosera regia (Gulmohar) tree is a class of the family Fabaceae. It is an ornament plant also called as flame tree. It is commonly known for its beautiful flowers. But it also has some pharmacological properties such as anti-diabetic activity, anti-bacterial activity, anti-diarrheal property, hepatoprotective/cytotoxic property, anti-microbial activity and antiinflammatory activity. It belongs to the family of Leguminosae. The phytochemically gulmohar contains sterols, phenolic compounds, triterpenoids, and falvonoids. Its flowers yielded saponins, flaonoids, carotenoides, tannins, steroids, alkaloids, and sterols. The bark of plant has sitosterol, carotene, hydrocarbons phytotoxins, saponins, alkaloids, and flavonoids. The stem bark of plant four triterpenes contains like as sitosterol, stigmasterol, lupeol, epilupeol, and an aromatic compound pmethoxybenzaldehyde. Their leaf contains sitosterol and lupeol (Shuhane et al., 2016).

Schleichera oleosa (Kusum) is well recognized tree of medicinal significance in India. All parts of this plant are using in Indian traditional healing. Kusum based natural formulations are very popular among the healers of current generation. Schleichera oleosa, belonging to the Sapindaceae family, has been reported to possess antimicrobial, antioxidant, anticancer activity, and can be used for the making of biodiesel. The plant contains low tannin levels therefore it can be used as fodder for livestock. This species contains important phytochemicals such as terpenoids, betulin, betulinic acid etc. Most of literature reveals that this medicinal plant can be used as a substitute to synthetic compounds for use in preventing and treating numerous diseases (Anuragi et al., 2017).

Materials and Methods

Plant Material

The plant leaves of D. regia and S. oleosa leaves were obtained from Botanical garden of Rani Durgavati University, Jabalpur MP, India, during the month of January. The standard drug, Albendazole was purchased from local market of Bhopal, Madhya Pradesh, India and test sample. All the other reagents were purchased of analytical reagent grade and used.

Preparation of plant extracts

Dried and powdered leaves of D. regia and S. oleosa were defatted firstly to remove fatty material, using petroleum ether solvent. The marc of plant material was kept for 1 week into ethanol and water mixture solvent (70:30). Then after 1 week filtered, evaporated and concentrated to dry residue. The residue was dried at desiccators. Finally the marc was macerated with distilled water (3 days) to obtain aqueous extract.

Evaluation of anthelmintic activity

Earth-worm Pheretima postuma was taken from Jawaharlal Nehru Krishi Vishwavidyalaya (JNKVV), Jabalpur Madhya Pradesh India. All earthworms were having equal size (4-7cm approximately). The anthelmintic activity was performed in-vitro by using adult Pheretima postuma worms owing to their physiological and anatomical similarity with the intestinal round worms.  The anthelmintic activity was investigated on adult Indian earthworm suitable to its anatomical and physiological similarity like the intestinal roundworm parasites of human beings. Eighteen groups, each consisting of six earthworms of about equal size were released in to 10 ml of suspension. Each group was treated with one of the following: vehicle standard albendazole (25 mg/ml, 50 mg/ml and 100 mg/ml), Hydroalcoholic extract of D. regia and S. oleosa. Observations were finished for the time taken to paralysis and death of individual worms. The death time was concluded when the worms lost totally their motility followed with fading away of their body colour (Tiwari et al., 2016; Gupta et al., 2015).

Results and Discussion

In vitro investigation results indicated that the hydroalcoholic extract of D. regia and S. oleosa leaves of plant extract at 100 mg/ml inhibited almost completely the mobility of isolated worms which is comparable with the reference standard drug albendazole. The present investigation, therefore, reveals that the hydroalcoholic extract D. regia was more potent than the S. oleosa at the doses of 25, 50 and 100 mg/ml. The results of anthelmintic activity reveal concentration dependent nature of different extracts. Potency of the herbal extracts was found to be inversely proportional to the time taken for paralysis and death of the worms. The phenolic compounds of both of plant leaves to produce anthelmintic activities (Gupta et al., 2013).

In conclusion, the traditional use of stem of D. regia and S. oleosa plant extract as an anthelmintic drug has been confirmed in our study. Further, it would be interesting to isolate the possible phytochemical constituents who might be responsible for the anthelmintic activity possible mechanism (s) of action can be elucidated. It might have some other antimicrobial activity.
