“…Kapoor et al (2009) recently demonstrated that the protective effect of piperine is most likely due to its antioxidant activity. Although a few reports on the antioxidant activity of cultivated P. nigrum are available in the literature (Singh et al 2008;Topal et al 2008;Aziz et al 2009;Misharina et al 2009 ), there seems to be no mention of the influence of organogenesis on antioxidant activity in P. nigrum. In the study reported here, we established an in vitro system for the production of P. nigrum from leaf explants of potted plants and conducted 1, 1-diphenyl-2-picrylhydrazyl (DPPH8)-based antioxidant assays to evaluate the antioxidant activity of the main secondary metabolites in different in vitro-derived tissues.…”

The organogenic potential and antioxidant potential (1, 1-diphenyl-2-picrylhydrazyl-scavenging activity) of the medicinal plant Piper nigrum L. (black pepper) were investigated. Callus induction and shoot regeneration were induced from leaf explants of potted plants cultured on MS medium supplemented with different plant growth regulators. The best callogenic response was observed on explants cultured for 30 days on MS medium supplemented with either 0.5 or 1.5 mg l -1 6-benzyladenine (BA) ? 1.0 mg l -1 a-naphthaleneacetic acid. Subsequent transfer of the callogenic explants onto MS medium supplemented with 1.5 mg l -1 BA ? 1.0 mg l -1 gibberellic acid (GA 3 ) achieved 85% shoot organogenesis after 30 days of culture. The maximum number (7.2) of shoots/explant was recorded for explants cultured in MS medium supplemented with 1.0 mg l -1 BA. Following the transfer of shoots to an elongation medium, the longest shoots (5.4 cm) were observed on MS medium supplemented with 1.0 mg l -1 BA ? 1.0 mg l -1 GA 3 . The elongated shoots were rooted on MS medium supplemented with different concentrations of indole butyric acid. An assay of the antioxidant potential of the in vitro-grown tissues revealed that the antioxidant activity of the regenerated shoots was significantly higher than that of callus and the regenerated plantlets.

“…Although a few reports on the antioxidant activity of cultivated P. nigrum are available in the literature. [26][27][28][29][30] The aim of the investigation presented in this paper is to evaluate the antibacterial and antioxidant activities of various extracts of Piper nigrum on several mastitis pathogens, as there is a significant lack of information on such activities in literature.…”

Objective / Purpose: Bacteria causes one of the most common types of chronic mastitis. The most common causative organisms of mastitis include: Staphylococci, Streptococci and coliforms. The scope of this work was to research the antibacterial effects of Piper nigrum extracts against mastitis pathogens, and its antioxidant capacity. Materials and Methods: In our study, 2 Staphylococcus aureus and 5 Coagulase Negative Staphylococcus were used for experiments. Additionally, Piper nigrum were collected from Mugla herbalists in Turkey. The plant extracts were tested by disc diffusion assay for antibacterial activity. The antioxidant activities of plant extracts were also determined by ABTS [2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)] method. Results: The methanol extract of plant showed maximum inhibition zone against 2 bacteria. MIC values of extracts are 6500 μg/mL. The value found in ABTS method is highly effective (75.7%). Discussion/Conclusion: As a result, the in vitro studies indicate that the extracts of Piper nigrum have significant antibacterial and antioxidant activities. In addition to, the plant extracts could be used in treating mastitis caused by the test bacteria.

“…The activity of α-and γ-terpinenes is comparable to that of α-tocopherol. This has been established both for juniper essential oils [34] and for pure terpene hydrocarbons: terpinolene, α-terpinene and γ-terpinene [35]. Myrcene, α-and β-pinene only exhibit lipid peroxidation in the second stage; sabinene, limonene, α-pinene and myrcene demonstrate anti-radical activity in relation to DPPH radical.…”

“…Anti-radical activity depends on the oil components, namely their chemical nature and concentration [34]. Regardless of its origin, juniper berry essential oil contains predominantly terpene hydrocarbons.…”

SummaryJuniperus communis L. (Cupressaceae) is a plant widely cultivated in the Northern hemisphere. Juniper berries, the fruit of Juniperus communis L. are a highly valued, essential oil-rich plant material used traditionally in folk medicine as antiseptic, diuretic, antirheumatic, anti-inflammatory, antibacterial and antifungicidal agent. This paper reviews information on extraction methods of the essential oil from the juniper berries, its chemical composition and antimicrobial as well as antioxidant properties.
