Synergistic antibacterial activity between Thymus vulgaris and Pimpinella anisum essential oils and methanol extracts
Journal of ethnopharmacology, 2007Co-Authors: Firas A. Al-bayatiAbstract:Essential oils (EOs) and methanol extracts obtained from aerial parts of Thymus vulgaris and Pimpinella anisum seeds were evaluated for their single and combined antibacterial activities against nine Gram-positive and Gram-negative pathogenic bacteria: Staphylococcus aureus, Bacillus cereus, Escherichia coli, Proteus vulgaris, Proteus mirabilis, Salmonella typhi, Salmonella typhimurium, Klebsiella pneumoniae and Pseudomonas aeruginosa. The essential oils and methanol extracts revealed promising antibacterial activities against most pathogens using broth microdilution method. Maximum activity of Thymus vulgaris and Pimpinella anisum essential oils and methanol extracts (MIC 15.6 and 62.5 μg/ml) were observed against Staphylococcus aureus, Bacillus cereus and Proteus vulgaris. Combinations of essential oils and methanol extracts showed an additive action against most tested pathogens especially Pseudomonas aeruginosa.

extraction kinetics and anethole content of fennel foeniculum vulgare and anise seed Pimpinella anisum extracts obtained by soxhlet ultrasound percolation centrifugation and steam distillation
Web Science, 2011Co-Authors: Patricia F Leal, Talyta S Almeida, Glaucia H C Prado, Juliana M Prado, Angela M A MeirelesAbstract:Foeniculum vulgare (fennel) and Pimpinella anisum (anise) extracts were obtained by Soxhlet, cold percolation, ultrasound assisted extraction, and centrifugal extraction using ethanol as solvent; anise extracts were also obtained by steam distillation. Soxhlet presented the highest yields for both fennel and anise seed (16.8% and 23.3%, respectively). The highest anethole content among ethanolic extracts was obtained for centrifugal extraction (6.8 mg/g and 143 mg/g for fennel and anise extracts, respectively). Steam distillation presented low yield (0.26%), but high anethole content (68–98%, area). Anise ethanolic extracts also tested positive for flavonoids.

economic analysis of rosemary fennel and anise essential oils obtained by supercritical fluid extraction
Flavour and Fragrance Journal, 2007Co-Authors: Camila G Pereira, Angela M A MeirelesAbstract:In the present work, economic analysis of the production of extracts and essential oils of rosemary (Rosmarinus officinalis), fennel (Foeniculum vulgare) and anise (Pimpinella anisum) by supercritical fluid extraction and steam distillation are discussed. The manufacturing cost (COM) was determined considering that the COM can be obtained in terms of the costs of investment, operational labour, raw materials, waste treatment and utilities. The manufacturing cost was also estimated considering that the essential oil content in SFE extracts varies (50–100%). The analysis showed that the supercritical fluid extraction is economically viable to obtain these vegetable extracts and essential oils. The higher costs of essential oils obtained by steam distillation were mainly caused by the lower yield and the higher energy consumption of this process. Copyright © 2007 John Wiley & Sons, Ltd.

Screening of Endophytic Bacteria from Purwoceng Roots (Pimpinella pruatjan Molk.) Antibacterial Activity Against Staphylococcus aureus
Journal of Biological Science and Education, 2021Co-Authors: Gp SartikaAbstract:Most antimicrobial agents, antifungus or antibacterial have been isolated from plants. Purwoceng (Pimpinella pruatjan Molk.) is one of the potential plants that produced an antibacterial agent. But, the status of purwoceng as an endemic plaint in Central Java is "endangered". The endophytic bacteria of the roots can produce an antibacterial agent. The research was performed by purified the endophytic bacteria isolate, the antagonism test as an antibacterial against Staphylococcus aureus also performed, and the data obtained were analyzed descriptively Keywords: Staphylococcus aureus, antibacterial, incubation, Purwoceng, secondary metabolit

a comparative study of the phenolic compounds and the in vitro antioxidant activity of different brazilian teas using multivariate statistical techniques
Food Research International, 2014Co-Authors: Acacio Antonio Ferreira Zielinski, Charles Windson Isidoro Haminiuk, Aline Alberti, Alessandro Nogueira, Ivo Mottin Demiate, Daniel GranatoAbstract:Abstract A total of 51 Brazilian teas from the species Camellia sinensis, Peumus boldus, Matricaria recutita, Baccharis trimera, Cymbopogon citratus, Pimpinella anisum, Mentha piperita, and Ilex paraguariensis were analyzed in terms of phenolic compounds, color and in vitro antioxidant capacity using ferric reducing antioxidant power (FRAP) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) assays. Data were processed using principal component analysis (PCA), hierarchical cluster analysis (HCA) and linear discriminant analysis (LDA). Significant (P
