Abstract

Peristrophe paniculata is one of the traditional medicinal plant have been using in treatment of different diseases. The present study was carried out to provide scientific evidence about its medicinal use and phytochemical variation in different parts (stem, leaves and root) of it. Phytochemical studies were carried out for hexane, ethyl acetate and hydro alcoholic extracts using standard test procedures and antioxidant activity was carried on different free radicals i.e., superoxide, hydroxyl and 1, 1- diphenyl-2-picrylhydrazyl (DPPH). Hydroalcoholic, ethyl acetate and hexane extracts of P. paniculata were found to possess concentration dependent free radical scavenging activity on superoxide, hydroxyl and DPPH free radicals. Qualitative phytochemical screening of P. paniculata extracts revealed the presence of diverse in phytochemical constituents like steroids, terpenoids, flavonoids, alkaloids, glycosides, phenols, tannins and carbohydrates. The extracts of different parts gave negative and positive results for the amino acids, oils and saponins. The selected plant extracts showed concentration dependent percentage of inhibition on tested free radicals along with the standard drug ascorbic acid. The hexane extract of all parts of P. paniculata showed lower activity compared to ethyl acetate and hydroalcoholic extracts. Hydroalcoholic extract showed better activity. The variation in the activity and phytochemical constituents in them maybe due to the compounds present in them either as individually or in mixtures. The further research is need to evaluate more pharmacological activities and in isolation of the bioactive compounds from P. paniculata.

Introduction

Medicinal plants play a central role in traditional medicines and are precursors for the modern pharmaceuticals/Allopathic medicines. Most of the natural products found in medicinal plants are the compounds biosynthetically derived from primary metabolites such as amino acids, carbohydrates and fatty acids and are generally categorized as secondary metabolites [1,2]. The high technology tests such as computer tomography scans, magnetic resonance imaging, endoscopies, radiotherapies and biopsies are expensive and often treatments frequently have side effects such as allergies, vomiting, headaches etc. whereas traditional remedies usually have none [3,4]. So, the traditional medicine is largely gaining popularity over allopathic medicine because of rising costs of medical care, free from side effects in several cases, easy availability of drugs from natural sources and etc. Different drugs from different parts of different plant sources shows various therapeutic activities and different biologically and pharmacologically active compounds were identified [5,6].

From earliest times and even today almost all drugs are intimately linked with plants and these plant products have extensive use in the ethno-medicine and traditional system of medicine. The untapped wealth of plant kingdom increased interest on medicinal plants enormously over last three decades. Thereby become target for the search of new drugs and lead molecules for treatment of different diseases [7-9]. In recent years, a comprehensive search on medicinal plants, pharmaceutical drugs recently published in clinical reports suggest the effectiveness of herbal remedies, their availability, low cost. Thus, the present study was carried out on evaluation of In-vitro antioxidant potential of different extracts of Peristrophe paniculata.

Peristrophe paniculata (Peristrophe bicalyculata) belongs to family Acanthaceae, is an erect, perennial plant with stems that can become more or less woody; it can grow up to 150 cm tall. Widespread through subtropical and tropical Africa, E. Asia-China, India, Nepal, Myanmar, through tropical Asia to Australia. Forest undergrowth, hedges, and wasteland. Weedy areas, roadsides at elevations from 600-2,200 meters [10]. The plant P. paniculata can be used as a green manure and has medicinal potential. Leaf juice have been used for healing fractured bones and plant material maceration used as antidote to snake poison and the plant material was also used for treatment of hypertension, cardiovascular diseases [9-13]. There is very few phytochemical and biological works were reported on P. paniculata [14-17].

Materials and Methods

Chemicals and drugs

The chemicals and solvents used in the current study were analytical grade from S.D. Fine Chemicals Pvt. Ltd., Mumbai. 1,1-diphenyl-2-picrylhydrazyl (DPPH) from Sigma Chemical Company, U.S.A., Riboflavin from Loba Chemic., Mumbai. Deoxyribose from Sisco Research Laboratories Pvt Ltd., Mumbai, Nitroblue tetrozolium from Sisco Research Laboratories Pvt Ltd., Mumbai.

Collection of plant material and preparation of extracts

The plant material was collected at Palnadu region, Andhra Pradesh, India, during the month November, 2017. The authentication of the plant was done by Rtd. Dr. Prayaga Murthy. Pragada, Department of Botany, Government Degree College, Yeleswaram, E. Godavari, Andhra Pradesh. Different parts of the plant were separated and shade dried. Then, plant materials were powdered and separately extracted using maceration process with hexane, ethyl acetate, and hydroalcoholic (ethanol (70% v/v)) were concentrated to dryness under vacuum using rotavapour.

Phytochemical analysis

Phytochemical studies were carried out for hexane, ethyl acetate and hydro alcoholic extracts of P. paniculata stem, leaves and roots separately to detect the presence of different phytochemical constituents like steroids, terpenoides, tannins, flavanoids, saponins, glycosides, amino acids etc. by using standard procedures [18-20].

In vitro antioxidant activity

For the assessment of antioxidant activity, the extract of B. roxburghii was dissolved in Dimethyl sulphoxide (DMSO). The results were showed in mean ± SEM. The Percentage Inhibition and 50% Inhibition Concentration’s (IC50) were calculated [18,21]. The each values were studied against blank in every assay of scavenging activity.

Superoxide radical scavenging activity

Superoxide scavenging activity of the selected plant extract was evaluated as per method [22]. It is by absorption of light at 560 nm induction of superoxide free radical generation by riboflavin and corresponding reduction by nitroblue tetrazolium.

Hydroxyl radical scavenging activity

The hydroxyl radical scavenging activity is measured as per established method. It was studied by the competition between deoxyribose and the extract’s antioxidant molecules for hydroxyl radicals generated from the Fe+2/EDTA/H2O2 system [23].

2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity

The DPPH radical scavenging activity was measured as per methods [24,25]. This method is based on measure of color absorbance of alcoholic DPPH solution (Blue color) after addition of antioxidant solution (Extract/Compound). If antioxidants present in the test compound blue color yellow color due to diphenyl-picrylhydrazine.

Calculation of percentage inhibition

The percentage inhibition of superoxide production by the extract was calculated using the formula: Inhibitory ratio=(A0- A1)/A0+100

Where, A0 is the absorbance of control; A1 is the absorbance with addition of plant extract/ ascorbic acid.

Calculation of 50% inhibition concentration

The optical density obtained with each concentration of the extract/ascorbic acid was plotted taking concentration on Xaxis and percentage inhibition on Y-axis. The graph was extrapolated to find the 50% inhibition concentration of extract/ ascorbic acid.

The extracts of P. paniculata root showed more percentage of inhibition at 320 μg. The IC50 values for the root extracts were not able to detect because they showed minimal below 50% inhibition on free radicals production. The percentage of inhibition on superoxide radical of hydroalcoholic, ethyl acetate and hexane extracts of P. paniculata root at 320 μg were found to be 19.4 ± 0.25, 38.3 ± 0.78 and 25.45 ± 0.75 respectively. The percentage of inhibition on hydroxyl radical of hydroalcoholic, ethyl acetate and hexane extracts of P. paniculata root at 320 μg were found to be 20.8 ± 0.6, 35.1 ± 0.8 and 39.3 ± 0.4 respectively. The percentage of inhibition on DPPH radical of hydroalcoholic, ethyl acetate and hexane extracts of P. paniculata root at 320 μg were found to be 12.28 ± 0.29, 14.35 ± 0.62 and 22.1 ± 0.13 respectively (Table 6). Among the samples, better DPPH free radical scavenging activity was found in hydroalcoholic root extract of P. paniculata.

Discussion

Free radicals are produced during metabolisms of the body. If they were produced in the normal level, the body produced antioxidants were sufficient to neutralize them without affecting the body [26]. Present day lifestyle are generating more oxidants in the body and the naturally available antioxidants in the body are not sufficient to neutralize excess amount [26,27]. The excess production of the oxidants in the body leading to unbalance physiological functions can causing different diseases like lipid peroxidation, DNA damage, atherosclorosis (oxidated LDL is more atherogenic), cancers, neurodegenerative and inflammatory bowel diseases and accelerated aging [28-30]. So, it is important to identify antioxidants without side effects and easily available and consumable [31].

Medicinal plants have attracted great attention for their potent biological activities, no side effects and economic viability over the past years. The biological activities (properties) of medicinal plants may be due to the presence of diverse group of chemical compounds like steroids, glycosides, phenolics, glycosides, anthocyanins, flavonoids etc. [32-34]. The search of biologically active compounds from medicinal plants has always been of great interest to scientists looking for new sources of useful drugs against different hazardous diseases. Many plant species have been investigated in the search for antioxidants but generally there is still a demand to find more information concerning the antioxidant potential of plant species [18,21,35,36]. Many studies have shown that natural antioxidants in medicinal plants closely related to their biofunctionalities, such as the prevention or suppression of aging and many diseases associated with oxidative stress, cancer, cardiovascular diseases, rheumatoid arthritis, autoimmune diseases and AIDS [37].

The present work carried out to identify variability in the presence of phytochemical compounds in different parts and antioxidant capacity of different parts of traditional medicinal plant, P. paniculata and we succeeded in identification of the medicinal value of P. paniculata scientifically. The phytochemical analysis of different parts extracts showed presence of different phytochemical compounds in them (Tables 1-3). The hexane extracts of P. paniculata showed mainly presences of steroids, terpenoids, oils and carbohydrates. Ethyl acetate extracts showed mainly presences of glycosides, flavanoids, alkaloids, phenols, tannins etc. Hydralcoholic extracts showed the presences of maximum compounds in them but have little variability compared to hexane and ethyl acetate extracts. The variation in the presence of phytochemical compounds may be due to their solubility in the solvents used for their extraction [38]. The presence of compounds may also varies from one region to other regions, because of their geographical variation.

The concentration dependent percentage inhibition of tested plants extracts varies from one free radical to other on tested free radicals. The hydralcoholic extract showed more activity on superoxide free radical and DPPH free radicals, hexane extract showed less activity. Among three parts extracts of P. paniculata, stem extracts showed more percentage inhibition on free radicals and the phytochemical analysis of different parts extracts showed presence of different phytochemical compounds in them. In recent decades, there were many scientific reports on medicinal plants about their antioxidant activities [25,38]. So, the results of the present study provide scientific evidence for its traditional medicinal uses.
