Objective: To investigate phytochemicals and biological activities of Capparis cartilaginea extracts.Methods: The methanolic extracts of leaves, stem and twigs of C. cartilaginea were screened for their phytochemicals. The essential oil of the leaves was hydrodistilled by a Clevenger apparatus and analyzed by gas chromatography-mass spectrometry (GC-MS). The leaves extract of C. cartilaginea was evaluated for its anti-inflammatory effect, using formalin-induced paw edema. The leaves, stem and twig extracts were assessed for their antioxidant activity, using free radical scavenging assay, cytotoxic activity, using 3-[4,5-dimethylthiazole-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay and antibacterial activity, using the microdilution method.Results: All extracts of C. cartilaginea contained alkaloids, carbohydrates, protein, coumarin, phytosterols, bitter principles, phenols and tannins. The essential oil of the leaves was mainly composed of isopropyl isothiocyanate (69.4%), butane,1-isothiocyanate (26.97%) and isobutyl isothiocyanate (3.26%). The leaves extract at doses of 200 and 400 mg/kg, significantly inhibited paw edema at the 3rd h (49.1%, 54.0%, respectively) and this effect was comparable to that of diclofenac (58.87%). The leaves extract showed the highest antioxidant activity with IC50 value of 91.71 µg/ml. The twigs extract exhibited the highest cytotoxic activity against human lung carcinoma (A549) with IC50 of 57.5 µg/ml. The leaves and stem extracts exhibited antibacterial activity against Staphylococcus aureus with minimum inhibitory concentration (MIC) of 5.0 mg/ml. Conclusion: The leaves extract of C. cartilaginea is a potential source of bioactive compounds that could have a role in anti-inflammation. Twigs extract of the C. cartilaginea possesses a potential cytotoxic effect on human lung cell line.

Essential oils (EOs) from Citrus are the main by-product of Citrus-processing industries. In addition to food/beverage and cosmetic applications, citrus EOs could also potentially be used as an alternative to antibiotics in food-producing animals. A commercial citrus EO—Brazilian Orange Terpenes (BOT)—was fractionated by vacuum fractional distillation to separate BOT into various fractions: F1, F2, F3, and F4. Next, the chemical composition and biological activities of BOT and its fractions were characterized. Results showed the three first fractions had a high relative amount of limonene (≥10.86), even higher than the whole BOT. Conversely, F4 presented a larger relative amount of BOT’s minor compounds (carvone, cis-carveol, trans-carveol, cis-p-Mentha-2,8-dien-1-ol, and trans-p-Mentha-2,8-dien-1-ol) and a very low relative amount of limonene (0.08–0.13). Antibacterial activity results showed F4 was the only fraction exhibiting this activity, which was selective and higher activity on a pathogenic bacterium (E. coli) than on a beneficial bacterium (Lactobacillus sp.). However, F4 activity was lower than BOT. Similarly, F4 displayed the highest antioxidant activity among fractions (equivalent to BOT). These results indicated that probably those minor compounds that detected in F4 would be more involved in conferring the biological activities for this fraction and consequently for the whole BOT, instead of the major compound, limonene, playing this role exclusively.

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.

Oregano (Poliomintha longiflora) essential oil (Ooil) is a product of high commercial value and many applications, including chemotherapy. Aiming to achieve the best use of this resource, the present study focuses on the characterization of separated fractions of Ooil by fractional vacuum distillation at low pressure. Four fractions (F1–F4) and undistilled oil (Unoil) were separated from Ooil and analyzed for their chemical composition and biological activities, such as antioxidant and antimicrobial activities. Gas chromatography–mass spectrometry shows differences in the composition among the fractions and Ooil. The amount of monoterpenes oxygenated (MO), sesquiterpenes hydrocarbon (SeH) and monoterpenes hydrocarbon (MH) varied between the fractions in ranges of 1.51–68.08, 3.31–25.12 and 1.91–97.75%, respectively. The major concentrations of MO and SeH were observed in F4 and Unoil. On the other hand, the highest concentrations of MH were found in F1 and F2, while the lowest were in F4 and Unoil. These results were correlated with the biological activity. Free-radical scavenging activity varied among fractions, with F4 and Unoil showing the highest activity. The antimicrobial test showed that F4 and Unoil had the highest activity in almost all cases. The correlation between the variables studied in the different fractions allows the definition of the particular properties for each one of them.

Nutmeg (Myristica fragrans) essential oil has antimicrobial, antiseptic, antiparasitic, anti-inflammatory, and antioxidant properties. We have recently demonstrated that hydrodistillation of nutmeg essential oil by applying magnesium aluminometasilicate as an excipient significantly increases both the content and amount of bioactive substances in the oil and hydrolats. In this study, we aimed to compare the antioxidant, antimicrobial, and anti-inflammatory activity of hydrolats and essential oil obtained by hydrodistillation in the presence and absence of magnesium aluminometasilicate as an excipient. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging method revealed that magnesium aluminometasilicate did not significantly improved antioxidant activity of both essential oil and hydrolat. Antibacterial efficiency was evaluated by monitoring growth of 15 bacterial strains treated by a range of dilutions of the essential oil and the hydrolats. Essential oil with an excipient completely inhibited the growth of E. faecalis, S. mutans (referent), and P. multocida, whereas the pure oil was only efficient against the latter strain. Finally, the anti-inflammatory properties of the substances were assessed in a fibroblast cell culture treated with viral dsRNR mimetic Poly I:C. The essential oil with an excipient protected cells against Poly I:C-induced necrosis more efficiently compared to pure essential oil. Also, both the oil and the hydrolats with aluminometasilicate were more efficient in preventing IL-6 release in the presence of Poly I:C. Our results show that the use of magnesium aluminometasilicate as an excipient might change and in some cases improve the biological activities of nutmeg essential oil and hydrolats.

The chemical components, as well as the antibacterial and antioxidant activities of the essential oil (EO) and crude extracts prepared from Rhodiola crenulata were investigated. The essential oil was separated by hydrodistillation, and gas chromatography-mass spectrometry (GC-MS) was used to identify its constituents. A total of twenty-seven compounds was identified from the EO, and its major components were 1-octanol (42.217%), geraniol (19.914%), and 6-methyl-5-hepten-2-ol (13.151%). Solvent extraction and fractionation were applied for preparing the ethanol extract (crude extract, CE), petroleum ether extract (PE), ethyl acetate extract (EE), n-butanol extract (BE), and water extract (WE). The CE, EE and BE were abundant in phenols and flavonoids, and EE had the highest total phenol and total flavonoid contents. Gallic acid, ethyl gallate, rosavin and herbacetin were identified in the EE. The antibacterial activity results showed that the EO exhibited moderate inhibitory activity to the typical clinic bacteria, and EE exhibited the strongest antibacterial activity among the five extracts. For the compounds, ethyl gallate showed the strongest inhibitory activity to the test bacteria, and its minimum inhibitory concentration (MIC) value and minimum bactericidal concentration (MBC) value for all the tested bacteria was 0.24 mg/mL and 0.48 mg/mL, respectively. The results of antioxidant activity showed that both CE and EE exhibited strong antioxidant activities in the DPPH radical scavenging and Fe2+ reducing power tests, however, EO showed relatively weaker antioxidant ability. Ethyl gallate and rosavin exhibited excellent activity in the DPPH radical scavenging assay, and their IC50 value was 5.3 µg/mL and 5.9 µg/mL, respectively. Rosavin showed better reduction power activity than the other three compounds. These results could provide more evidence for the traditional use of R. crenulata, and would be helpful for improving its application further.

Diploknema butyracea (Roxb.) H.J. Lam is a multipurpose tree used by the Nepalese indigenous people for medicinal purposes such as rheumatism, asthma, and ulcer and other purposes such as cooking and lighting. However, there is no scientific evidence for the medicinal uses of this plant. The present study aimed to explore the phytochemical constituents, estimate the total phenolic content, evaluate antioxidant activity, and investigate the in vivo anti-inflammatory and analgesic activities of aqueous extract of Diploknema butyracea (Roxb.) H.J. Lam bark (ADBB). Phytochemical screening was performed using standard methods. The total phenolic content was determined using the Folin–Ciocalteu method. The in vitro antioxidant activity was determined using 2, 2-diphenyl-1-picrylhydrazyl radical scavenging assay and nitric oxide radical scavenging assay. For the in vivo studies, the plant extract was given in three different doses (50, 100, and 200 mg/kg body weight) to male albino Wistar rats. Anti-inflammatory and analgesic studies were carried out using the carrageenan-induced rat paw edema and the hot plate method, respectively. Results revealed the presence of different phytoconstituents such as flavonoids, tannins, glycosides, terpenoids, and carbohydrates together with a considerable amount of phenolic compounds. Antioxidant assays indicated the potent antioxidant activity of the plant extracts. The higher dose of D. butyracea (200 mg/kg) exhibited a maximum and significant inhibition (53.20%) of rat hind paw edema volume at 4 h and showed a greater increment in latency time (12.15 ± 1.81 sec) in the hot plate test at 120 min. The present study demonstrated the antioxidant, anti-inflammatory, and analgesic potential of ADBB, which supports its traditional medicinal use.

This study evaluated the antioxidant and anti-inflammatory properties of Marantochloa leucantha (Marantaceae). The in vitro antioxidant activity of the extracts and solvent fractions was evaluated by 1,1-diphenyl- 2-picrylhydrazyl (DPPH) radical scavenging and ferric reducing antioxidant potential (FRAP) assay models and in vivo anti-inflammatory activity by the rat paw edema model. The phytochemical screening indicated the presence of tannins, terpenoids, steroids, flavonoids, reducing sugar and phenolics. The antioxidant assay showed that all the extracts exhibited high antioxidant activity comparable with ascorbic and gallic acid controls. In DPPH model, a 250 μg/ml EtOAc fraction of the leaves showed antioxidant activity of 93.9 ± 1.7 % (EC50 0.82 μg/ml) and a 1000 μg/ml of same stem fraction produced 91.9 ± 0.3 % activity (EC50 1.38 μg/ml). In the FRAP model, EtOAc fraction exhibited 31.1±0.7 and 92.0 ± 2.2 μM Fe2+/g of dried leaves and stem, respectively at 1000 μg/ml FeSO4 equivalent. The anti-inflammatory potential of the plant showed that the crude stem extract and fractions at 200 - 600 mg/kg exhibited significant (p < 0.01) dose-related inhibition of paw edema in rats. A 200 mg/kg EtOAc fraction showed 18.8 % inhibition compared to 31 % observed in diclofenac-treated rats in 2 h post albumin challenge. These findings validated the folkloric use of this plant in the treatment of diseases associated to the oxidative stress and could further provide promising lead compounds with potent antioxidant and anti-inflammatory activities Dhaka Univ.

The essential oil yield, volatile profile and antioxidant activity, of 37 samples collected from the Rosmarinus officinalis shrubs growing wild in the different ecosystems of the provinces of Taourirt and Jerada (Oriental region in the east of Morocco), were studied in order to determine the effect of the habitat and how the vegetal associations are influencing the volatile variability of their essential oil. The essential oil compositions were determined by gas chromatography-mass spectrometry (GC-MS). The yield of the essential oil extraction ranged from 1.09 to 2.81 %. The major components found were 1.8-cineol (37.71-65.02 %), camphor (6.09-27.49 %), α-pinene (3.08-9.98 %) and β-pinene (2.83-11.7 %). The interpretation of these results revealed that the variability is attributed to varieties and genetic background rather than the ecosystems. The antioxidant activity was determined by 1,1-diphenyl-1-picrylhydrazyl (DPPH) assay which revealed a strong radical scavenging capacity for all the samples with some variability which can be explained by the variability of the content of monoterpenes oxygenated.
