Topical Wound Healing, Antimicrobial and Antioxidant Potential of Mimosa pudica Linn root Extracted using n-Hexane Followed by Methanol, Fortified in Ointment Base

Mimosa pudica Linn is an ornamental perennial herb belonging to the taxonomic group of Magnoliopsida and family Leguminaceae. Besides its ornamental use, Mimosa pudica is also a popular plant among folk healers to treat several diseases including bleeding disorders such as menorrhagia, dysentry with blood, mucus and piles, and wound healing. In this study, roots of Mimosa pudica was successively extracted with hexane, ethyl acetate, and methanol to evaluate the folkloric assert of plant in view of antioxidant, antibacterial, and wound healing potential. Methanolic extract showed concentration dependent elevation in inhibition for radical scavenging assay following dpph with maximum effect of 73.43% against standard ascorbic acid equivalent to 250 µg/ml, however IC50 of extract with n-hexane and ethyl acetate exhibited relatively poor antioxidant efficacy. Minimum inhibitory concentration demonstrated higher inhibitory action in range of 1.25-0.625 mg/ml against tested gram positive Staphylococcus aureus -MTCC737, and Bacillus subtilis-MTCC110 and 2.5 mg/ml for gram negative Salmonella typhi-MTCC15442, Escherichia coli-MTCC118 micro-organism for methanolic extract compared to ethyl acetate extract, however hexane extract showed MIC > 2.5 mg/ml. Among the tested solvent system for column chromatography, fractionation with diethyl ether: methanol (1:4) demonstrated single clear spot with Rf value 0.72 for methanolic extract indicated presence of flavonoid as major phytoconstituents. The results of spectral analysis following fourier transform spectroscopy, nuclear magnetic resonance, and mass spectroscopy for purified isolated compound confirmed identity of isolated flavonoid from methanolic fraction with chemical name 7,8,3’,4’-tetrahydroxy-6-methoxy-flavone. Thus, overall results demonstrated that Mimosa pudica root extract have potential antioxidant and antimicrobial efficacy. Furthermore, the Mimosa pudica root extracted with n-hexane followed by methanol fortified in a pharmaceutical formulation ointment base demonstrated excellent wound healing efficacy compared to marketed povidone-iodine ointment. Therefore, traditional claim for the use of Mimosa pudica root as potential antioxidant, antimicrobial, and wound healer in topical drug delivery have been proven by the present study.

Abstract Background Abrus precatorius possesses various therapeutic properties including anticancer potentials. This study evaluated the anti-proliferative activities of fractions of methanol root extract of A. precatorius on breast and cervical cancer cells and their immunomodulatory effect. Phytochemical screening was done by FTIR and GCMS. In vitro anti-proliferative effect was evaluated on human breast cancer (AU565) and cervical cancer (HeLa) cells and on murine fibroblast (NIH 3 T3) cells. Antioxidant activity was performed via DPPH radical scavenging assay. The immunomodulatory potential of fractions was evaluated by inhibition of phagocytes oxidative burst (ROS), Nitric oxide (NO) and proinflammatory cytokine TNF-α. Results A. precatorius fractions showed different chemical groups and were somewhat selective in antiproliferative activity against studied cancer cells. Ethyl acetate fraction showed the most significant antiproliferative activity with IC50 values of 18.10 μg/mL and 11.89 μg/mL against AU565 and HeLa cells respectively. Hexane fraction significantly (p < 0.05) inhibited HeLa cells (IC50 18.24 ± 0.16 μg/mL), whereas aqueous fraction showed mild inhibition (IC50 46.46 ± 0.14 μg/mL) on AU565 cell proliferation. All fractions showed no cytotoxicity against NIH-3 T3 murine fibroblast normal cells. All fractions showed potent and significant (p < 0.001) DPPH radical scavenging activity as well as suppressed phagocytic oxidative burst. Hexane (< 1 μg/mL), ethyl acetate (< 1 μg/mL), and butanol (5.74 μg/mL) fractions potently inhibited the cytokine TNF- α, hexane (< 1 μg/mL) and ethyl acetate (< 1 μg/mL) fractions also potently inhibited NO. Conclusions The antiproliferative activities and suppressive effect on the phagocytic oxidative burst, NO and proinflammatory cytokine might be due to the synergistic actions of bioactive compounds especially flavonoids present in the assayed fractions and therefore, suggest chemotherapeutic use of A. precatorius in cancer treatment.

ABSTRACT: In the present study, antibacterial and antioxidant [1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity] activities of a weed, slender amaranth (Amaranthus viridis L.) were investigated. Extracts of different plant parts were prepared in n-hexane, chloroform and ethyl acetate. Antibacterial activity was measured by using 100 mg mL-1 concentration extracts against 4 deadly phytopathogenic bacterial species viz. Pseudomonas syringae Van Hall, Ralstonia solanacearum Smith, Erwinia carotovora (Jones), Holland and Xanthomonas axonopodis Hasse. In antioxidants assays, 10, 20 and 30 mg mL-1 extracts were used keeping DPPH as control. In these bioassays, ethyl acetate fraction of A. viridis leaf exhibited the best antibacterial and antioxidants activity. Ethyl acetate leaf fraction showed the highest inhibition zone diameter (IZD) where it caused 21 mm IZD against P. syringae and 19 mm IZD against E. carotovora. This extract also showed 22, 52 and 84% antioxidant activity at 10, 20 and 30 mg mL-1 concentrations, respectively. Previously there is no report available that describes antibacterial activity of root extract of A. viridis against P. syringae. Moreover, antioxidant activity of stem and root extracts in n-hexane, chloroform and ethyl acetate was investigated first time in the world. It was concluded that the biological activities observed during the present investigation may be due to the presence of bioactive constituents that can be harnessed as natural antibacterials and antioxidants.

Background: This study examined the in vitro antibacterial property of extracts of Moringa oleifera and the effect of different concentrations of the ethyl-acetate extract on cutaneous wound using an ointment delivery base. The aim of the study was to screen the extracts with best antibacterial property and evaluate effectiveness of different concentrations of the best extract when delivery is modified to ensure prolonged contact and reduced frequency of administration using an ointment base delivery vehicle. Materials and Methods: Dried and pulverized leaves of Moringa oleifera were screened for secondary metabolites. Successive gradient extraction was carried out using n-hexane, ethyl acetate and methanol. Leaf extracts were screened against clinical wound isolates of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae and Proteus mirabilis using agar cup diffusion technique. The ethyl acetate extract was investigated for its healing efficiency on excision wound model in rats. The study made use of wistar rats (150-180 kg), randomized into Gentamicin, M. oleifera ointment (5% and 3.25%), and ointment base treatment groups. Treatments were applied topically on days 0, 7 and 14. The percentage wound closure rate was measured and histopathology of the healed wounds carried out. Results: In vitro antimicrobial screening showed that ethyl-acetate extract was effective against the test isolates. Topical application of ointment with 3.25% of the plant extract resulted in faster wound closure rate, rapid epithelization, resolution of granulation tissue, and remodeling at histology. Conclusion: This may be due to less interference by components of M. oleifera which appear to retard wound healing at higher concentrations. Therefore, M. oleifera 3.25% ointment preparation is recommended topically for wound healing.

Rumex crispus is a perennial plant that grows in humid environments across Korea. Its roots are used in traditional Korean medicine to treat several diseases, including diseases of the spleen and skin and several inflammatory pathologies. In this study, different solvent fractions (n-hexane, dichloromethane, ethyl acetate, n-butanol, and aqueous fractions) from an ethanol extract of R. crispus roots were evaluated for the presence and composition of anthraquinone compounds and antioxidants by checking for such things as free radical scavenging activity, and electron and proton atom donating ability. In addition, anti-inflammatory activity was measured by NO scavenging activity and inflammatory cytokine production; furthermore, anti-cancer activity was measured by apoptosis-inducing ability. Polyphenolic and flavonoid compounds were shown to be abundant in the dichloromethane and ethyl acetate fractions, which also exhibited strong antioxidant activity, including free radical scavenging and positive results in FRAP, TEAC, and ORAC assays. HPLC analysis revealed that the dichloromethane fractions had higher anthraquinone contents than the other fractions; the major anthraquinone compounds included chrysophanol, emodin, and physcione. In addition, results of the anti-inflammatory assays showed that the ethyl acetate fraction showed appreciable reductions in the levels of nitric oxide and inflammatory cytokines (TNF-α, IL-1β, and IL-6) in Raw 264.7 cells. Furthermore, the anthraquinone-rich dichloromethane fraction displayed the highest anticancer activity when evaluated in a human hepatoma cancer cell line (HepG2), in which it induced increased apoptosis mediated by p53 and caspase activation.

Phytochemical Constituents

The objective of the present study is to investigate the phytochemical constituents by qualitative and quantitative analysis, pharmacological activities such as antioxidant, antidiabetic, anti-inflammatory, thrombolytic and antibacterial activities of different crude extracts from bark of Sterculia urens Roxb. Further, the preparative HPLC isolation and spectroscopic characterization of the bioactive phytochemical constituents were also carried out. Different solvents such as n-hexane, ethyl acetate, methanol and water were used to prepare the crude extracts from the bark using Soxhlet extraction apparatus. DPPH free radical scavenging assay (antioxidant), α-amylase inhibition assay (antidiabetic), albumin denaturation assay (anti-inflammatory), blood clot lysis method (thrombolytic) and well-diffusion method (antibacterial) were performed for the determination of pharmacological activities of the bark extracts. The preparative HPLC analysis was carried for the separation and purification of bioactive compounds and the identification of isolated compounds was carried using 1H NMR, 13C NMR and mass spectroscopy. The quantitative estimation studies confirmed that methanolic extract contains 7.75 ± 0.141 GAE/g of phenolic compounds, 10.47 ± 0.033 mg of QE/g of flavonoids and 8.70 ± 0.047 mg/g of terpenoids. The ethyl acetate extract contains 2.16 ± 0.126 GAE/g of phenolic compounds whereas the aqueous extract contains 16.53 ± 0.055 mg/g of saponins. High DPPH radical scavenging was observed for methanolic extract with IC50 concentration of 85.38 ± 0.213 μg/mL. The α-amylase inhibition activity with IC50 concentrations of 145.67 ± 1.87, 98.36 ± 0.47 and 194.47 ± 0.55 μg/mL for ethyl acetate, methanol and aqueous extracts respectively. The albumin denaturation inhibition activity was found to be very high for methanolic extract with IC50 values of 132.08 ± 0.13 μg/mL which is near to the standard (107.13 ± 0.13 μg/mL). The % clot lysis of the methanolic extract in thrombolytic activity was found to be similar to the 100 μL of streptokinase (62.36 ± 0.140 %). Two terpenoids (One known terpenoid mansonone G and one new terpenoid) were isolated from the methanolic extract using preparative HPLC separation. Three known flavonoids (farrerol, apigenin and 6-hydroxyluteolin) and one new flavonoid were also isolated from the methanolic extract. The results suggested that bark extracts of Sterculia urens Roxb. having rich phytochemical constituents with high pharmacological activities.
