Dittrichia viscosa which belongs to the Asteraceae family is frequently used to treat hematomas and skin disorders in Mediterranean herbal medicine. This study aims to validate its antioxidant effects and its potential on healing wounds. The ethanolic extract of D. viscosa leaves was formulated as 2.5% and 5% (w/w) in ointment bases on the beeswax and sesame oil. During this study, the ethanolic D. viscosa extract, ointments containing 2.5% and 5% of D. viscosa extract, and the vehiculum were assessed for their total phenol content (TPC), caffeoylquinic acid content (CQC), and antioxidant activities using complementary methods (TAC, the DPPH, ABTS, FRAP, and the BCB). The effects on wound healing of obtained ointments were evaluated by excision of the wound in a mice model for 12 days. Subsequently, the excised wound areas were measured at the 3rd, 9th, and 12th days. The skin tissues were isolated for histological studies. The ointments containing D. viscosa extract (2.5%, 5%) possessed a considerable TPC, CQC, radical scavenging potential, and antioxidant activities compared to the vehiculum. Treated animals with ointments containing D. viscosa extract at 2.5% and 5% showed almost and totally healed wounds compared to the vehiculum and control groups, evidenced by good skin regeneration and reepithelialization. The present work showed the role of D. viscosa antioxidants exerted by its polyphenolic compounds, in particular, caffeoylquinic acids, in enhancing wound healing.

The study aimed at evaluating the antioxidant profile of a medicinal epiphyte Viscum album L. harvested from three tree species, namely, Populus ciliata L, Ulmus villosa L., and Juglans regia L. The crude extracts were obtained with ethanol, methanol, and water and were evaluated for the total phenol content (TPC), total flavonoid content (TFC), and antioxidant activities using total reducing power (TRP), ferric reducing antioxidant power (FRAP), 1, 1-diphenyl 1-2-picryl-hydrazyl (DPPH), superoxide radical scavenging (SOR), and hydroxyl radical scavenging (•OH) assays. Our results showed that crude leaf extracts of plants harvested from the host Juglans regia L. exhibited higher yields of phytochemical constituents and noticeable antioxidative properties. The ethanolic leaf samples reported the highest phenols (13.46 ± 0.87 mg/g), flavonoids (2.38 ± 0.04 mg/g), FRAP (500.63 ± 12.58 μM Fe II/g DW), and DPPH (87.26% ± 0.30 mg/mL). Moreover, the highest values for TRP (4.24 ± 0.26 μg/mL), SOR (89.79% ± 0.73 mg/mL), and OH (67.16% ± 1.15 mg/mL) were obtained from aqueous leaf extracts. Further, Pearson correlation was used for quantifying the relationship between TPC, TFC, and antioxidant (FRAP, DPPH, SOR, OH) activities in Viscum album L. compared to their hosts. It was revealed that the epiphyte showed variation with the type of host plant and extracting solvent.

Abstract Incidence of various dreadful microbial infections and the development of antibiotic resistance by infection causative microbes are the main reasons for reducing aquaculture productivity. Hence, there is an immense need for the discovery of alternative and efficient treatment for quick recovery of diseased fishes. In the present study, Suaeda maritima leaf extracts (hexane, diethyl ether, ethanol, and water) were screened for in vitro and in vivo antibacterial and antioxidant activities. Out of all the four extracts, ethanolic extract showed highest antibacterial activity against S.aureus (4.9±1.3 mm), B.subtilis (1.6±0.3 mm), K.pneumonia (4.2±1.8 mm), and P.aeruginosa (4.1±1.2 mm). Similarly, antioxidant activity was also higher for ethanolic extract (500 µg/ml) based on DPPH radical scavenging ability (71.6±1.4 %) and reducing potential (149 μg/mL) assays. Further, ethanolic extract was purified consecutively via column chromatography and preparative TLC where an active fraction was selected based on highest antibacterial (10.1±1.4 mm) and antioxidant properties (82.3±2.8 %). Active fraction was loaded onto mass spectroscopy and identified the presence of four active constituents such as 1,2,9,10-tetramethoxy-6-methyl-5,6,6a,7-tetrahydro-4H-dibenzo[de,g]quinolin-3-yl) methanol; 3',7-Dimethoxy-3-hydroxyflavone; Saponin and (19R)9acetyl19hydroxy10,14dimethyl20oxopentacyclo[11.8.0.0<2,10>.0<4,9>.0<14,19>]henicos-17-yl-acetate. Besides, in vivo studies were conducted on Catla catla fingerlings infected with P. aeruginosa under laboratory conditions. The fingerlings were segregated into 5 groups, among which group 4 and 5 were treated with crude and purified extracts. Both the extracts were efficient in treating infected fingerlings and recorded 100% survival rate which is even better than group-3 treated with a synthetic antibiotic (77%). Hence, S. maritima leaf extract can be considered as a possible alternative medicine in aquaculture

The presence of natural antioxidant in plants is well known. Plant phenolics constitute one of the major groups of components that act as antioxidant and free radical terminator. Hence, this study focused on investigating the antioxidant activity of Celery plant (Apium graveolens L). The fresh leaves were collected, crushed and extracted with ethanol and acetone by maceration. The radical scavenging properties of the extracts were determined by measuring changes in absorbance of DPPH radical at a wave lenght of 517 nm by UV and ascorbic acid is used as the standard. It showed that the crude ethanolic extract has higher antioxidant activity compared to ascorbic acid and acetone extract with less scavenging activity. The values were (IC50 114.6 µg/mL) for ascorbic acid, (IC50 112 µg/mL) for the crude ethanolic extract and (IC50172 µg/mL) for crude acetone extract. The result shows that Celery plant grown in Jos possess good antioxidant properties which may be linked to the presence of phenolics and flavonoids in the plant, which justifies its use as a medicinal plant. This can be further investigated for the isolation and identification of active compounds of medicinal utilities.

Bacillus Clausii

Humans and plants are experiencing different kinds of diseases. Many of these diseases are mainly caused by microorganisms like fungi, bacteria and viruses that adversely affect their hosts. Bioactive compounds produced by bacteria can be used to treat the infections caused by these microorganisms. Free radicals that can cause serious damage to the cell can be repressed by antioxidants that are produced by bacteria as secondary compounds. The current case study was therefore planned to investigate the antimicrobial and antioxidant potentials of the organic and aqueous extracts of Bacillus clausii KP10 isolated recently by our group from hot springs of Tatta Pani, Poonch, Azad Kashmir. The antimicrobial activities were assessed using well diffusion method against two Gram positive bacteria; B. subtilis, and S. aureus, and two Gram negative bacteria; E. coli and P. multocida and three fungal strains; A. niger, A. parasiticus and A. ustus. Antioxidant activities of the extracts were done by DPPH free radical scavenging assay. In our experiments the maximum zones of inhibition were shown by ethanolic extract against P. multocida (21 mm), S. aureus (13 mm) and methanol soluble fraction showed zone of inhibition against A. ustus (21 mm) as compared to the standard ciprofloxacin for bacteria and as antifungal agents with terbinafine. In our studies n-hexane fraction of B. clausii KP10 showed maximum 88.67% antioxidant activity. Finally, results were analyzed statistically through analysis of variance (ANOVA). Hence it is proved that the bioactive fractions obtained from B. clausii KP10 are good source of antimicrobials and antioxidants and they can be used as medicines in future for the respective treatments.

The aril (mace) of Myristica fragrans, known as Dok-Chan, is a spice that has long been used for treating stomach discomfort, peptic ulcer, and nausea. It is an ingredient in many remedies in Thai traditional medicine, e.g., Ya-Hom-Thep-Bha-Jit, Ya-Hom-Nao-Wa-Kot, and Ya-That-Bun-Job, which are used to treat dyspepsia and other gastrointestinal tract symptoms. The aqueous and ethanolic extracts of mace were used for all tests. Anti-H. pylori activities were determined by the disc diffusion method and agar dilution. Anti-inflammatory activity was determined by the LPS-induced nitric oxide (NO) inhibition in a RAW264.7 cell line, and cytotoxicity was determined against gastric cancer cell lines (Kato III) using the sulphorhodamine B (SRB) assay. The DPPH radical scavenging and ABTS radical cation decolorization assays were used to determine the antioxidant activities. The result found that the ethanolic extract of mace exhibited antimicrobial activity against H. pylori ATCC 43504 and six clinical strains with MIC values of 125–250 μg/ml. The aqueous extract MICs against H. pylori ATCC reference strain and six clinical strains were 500 μg/ml compared with 0.5 μg/ml for the positive control, clarithromycin. The inhibitory effect of LPS-induced NO release and cytotoxic activity of the ethanolic extract had IC50 values of 82.19 μg/ml and 26.06 μg/ml, respectively, and the EC50 values for the DPPH and ABTS antioxidant assays were 13.41 μg/ml and 12.44 μg/ml, respectively. The mace extract also had anticancer properties. In conclusion, the ethanolic mace extract had anti-H. pylori, anti-inflammatory, antioxidant, and anticancer activities. These data support further preclinical and clinical investigation to see if the mace extract could have a role in treating patients with dyspepsia, peptic ulcers, and possibly gastric cancer.

In current research, the synthesis of gold nanoparticles was achieved via reducing of gold ions in aqueous solution with Garcinia mangostana (G. mangostana) peel extract. The optimum concentration of gold (Au) solution, concentration ratio of Au solution and extract, temperature, time and pH, the synthesized AuNPs (G. mangostana-gold nanoparticles) were studied by using UV-Vis, FT-IR, AAS, AFM, SEM and Zitasizer. The absorbance peak is noticed between 535-550 nm via UV-Vis spectroscopic method. The SEM, AFM analysis were proofed the particle as spherical in structure and their size between 15-100nm. Therefore, mechanism of AuNPs synthesis had been suggested. Also, the antibacterial activity was examined using different bacteria as well as free radical scavenging activity was tested using 1, 1-Diphenyl-2-picrylhydrazyl (DPPH). The AuNPs produced through biosynthesized method indicated a much elevated antioxidant activity as compared to peel extract of G. mangostana. Toxicity of the NPs and extract were tested via giving orally dose 50 mg/b.w. to mice. Diagnosis of the data (pathological changes) indicated that the AuNPs was non-toxic. The G. mangostana peel extract and AuNPs synthesized by this extract were converted to a cream and used as a wound healing cream. As a results, the AuNPs exhibited important role in wound healing progression compared to control, which may be attributed to their anti-inflammatory, antibacterial and antioxidant activities. Therefore, this research confirms its important use of AuNPs and can be utilized as promising agents for in the development of new drugs.

Hepatoprotective and antioxidant activity of Lannea coromandelica bark extract (LCBE) was investigated on thioacetamide induced hepatotoxicity in rats. Hepatotoxicity was induced by thioacetamide (TAA) administration (100 mg/kg. s.c). LCBE at different doses (400 and 200 mg/kg) were administered orally to male wistar rats. Thioacetamide caused elevation of serum concentration of AST, ALT, ALP, serum bilirubin and also reduced serum concentration of total protein, albumin, sodium, potassium in animals as compared to control (p < 0.05) but LCBE treated rats showed maximum reduction of AST [(138±5.1) IU/L], ALT [(71 ±2.7) IU/L], ALP [(140 ±1.9) IU/L] with the high dose (400 mg/kg bw) of combined aqueous and alcoholic bark extract. Whereas, serum bilurubin, cholesterol, sugar and LDH content were varied with the treatments but showed higher with the only ethanolic extract at dose of 400 mg/kg. The IC50 value was observed as (83.28 ±2.12) µg/mL, for DPPH radical scavenging activity. Result concluded that ethanolic extract and combined aqueous and alcoholic bark extract of L. coromandelica showed a potential hepatoprotective and antioxidant activities might be due to the presence of phenolic groups, terpenoids and alkaloids.
