In-vitro anti-cholinesterase activity of essential oil from four tropical medicinal plants

The toxic effect of essential oil from waste cinnamon leaf (Cinnamomum burmanii) against pests of cocoa fruit Helopeltis antonii (Hemiptera; Miridae), has been done in Green House, Research Station Spice and Medicinal Plants, Laing Solok, West Sumatra in April to May 2016. The experiment aimed to determine repellant and lethal concentrations of essential oil from waste s cinnamon leaf (C. burmanii) for H. antonii. There were 5 treatments arranged in Complately Randomized Design with 4 replications. The treatments tested were essentialoil concentration f (0.05 ml/tube, 0.1 ml/tube, 0.2 ml/tube and 0.5 ml/tube) and control. The results showed that the effective repellent concentration were 0,05 ml/tube and 0,1 ml/tube which repelled H. antonii 0,03 % . The effecive lethal concentration was 0,05 ml/tube which killed H. antonii 57,50 %. Concentration used was highly toxic which killed l H. Antonii within six hours so of the repellent nature was notobserved.

Ethanol Extracts

The objective of this study was to evaluate the in vitro antifungal properties of ethanol extracts and essential oils of medicinal plants from Serbia against Candida albicans (C. albicans) ATCC 10231. Ethanol extracts of fifteen plants were investigated, and their effects were compared with those of three different essential oils. The sensitivity of C. albicans to all plants was tested by the agar dilution method. The assay plates were estimated to contain 300, 150, 75, and 37.5 µg/ml of active extracts and 100, 50, 25, and 12.5 µg/ml of active essential oils. Inocula were applied to agar surfaces, giving approximately 106 cfu/ml of C. albicans. No inhibitory effects were observed for ethanol extracts of Hypericum perforatum and Salvia officinalis (MIC > 300 µg/ml). The most effective were the ethanol extract of Aesculus hippocastanum (MIC = 37.5 µg/ml) and the essential oil of Satureja kitaibelii (MIC = 12.5 µg/ml). Other plants showed MIC from 25 to 300 µg/ml. As far as we know, the inhibitory effects of these medicinal plants against the reference strain of C. albicans have not been commonly investigated in our country. Although the essential oil of Satureja kitaibelii shows strong activity against C. albicans, these results need clinical evaluation..

The GC-MS analysis of the essential oil from Tanacetum corymbosum revealed the presence of 38 compounds, including terpenes - germacrene D, (Z)-β-farnesene, g-elemene, β-caryophyllene, aliphatic - palmitic and linoleic fatty acids, fatty alcohol n-octadecanol, higher alkane n-heneicosane as the major constituents. The in vitro antimicrobial assessment of the ethanolic extract showed promising antibacterial/antifungal activities against five Gram-(+), Gram-(-) and phytopathogenic bacteria species and two fungi strains. The data obtained in this study may be useful both for researchers and for producers interested in new or less studied species of medicinal plants in healthcare and their biological activities.

The aim of this study is to establish an improved shoot regeneration of potential medicinal plants, Melaleuca alternifolia. The essential oil of these plants is useful in the cosmetic and pharmaceutical industries. Despite the importance of this species, in vitro regeneration was limited. Therefore, the present study use various concentrations of plant growth regulators to improve shoot regeneration of these plants. The present study shows that axillary shoot gave the best response to the treatment containing 0.5mg/L BAP and 0.1mg/L NAA. The average number of shoots is 23 with 77% of shooting. For rooting experiment, 35% of axillary shoot were rooted when cultured on MS medium supplemented with 1.5mg/L IBA. In vitro plantlet was later developed after 3 months.

Anti Inflammatory

Artemisia jordanica (AJ) is one of the folkloric medicinal plants and grows in the arid condition used by Palestinian Bedouins in the Al-Naqab desert for the treatment of diabetes and gastrointestinal infections. The current investigation aimed, for the first time, to characterize the (AJ) essential oil (EO) components and evaluate EO’s antioxidant, anti-obesity, antidiabetic, antimicrobial, anti-inflammatory, and cytotoxic activities. The gas chromatography-mass spectrometer (GC-MS) technique was utilized to characterize the chemical ingredients of (AJ) EO, while validated biochemical approaches were utilized to evaluate the antioxidant, anti-obesity and antidiabetic. The microbicidal efficacy of (AJ) EO was measured utilizing the broth microdilution assay. Besides, the cytotoxic activity was estimated utilizing the (MTS) procedure. Finally, the anti-inflammatory activity was measured utilizing a COX inhibitory screening test kit. The analytical investigation revealed the presence of 19 molecules in the (AJ) EO. Oxygenated terpenoids, including bornyl acetate (63.40%) and endo-borneol (17.75%) presented as major components of the (AJ) EO. The EO exhibited potent antioxidant activity compared with Trolox, while it showed a weak anti-lipase effect compared with orlistat. In addition, the tested EO displayed a potent α-amylase suppressing effect compared with the positive control acarbose. Notably, the (AJ) EO exhibited strong α-glucosidase inhibitory potential compared with the positive control acarbose. The EO had has a cytotoxic effect against all the screened tumor cells. In fact, (AJ) EO showed potent antimicrobial properties. Besides, the EO inhibited the enzymes COX-1 and COX-2, compared with the anti-inflammatory drug ketoprofen. The (AJ) EO has strong antioxidant, antibacterial, antifungal, anti-α-amylase, anti-α-glucosidase, and COX inhibitory effects which could be a favorite candidate for the treatment of various neurodegenerative diseases caused by harmful free radicals, microbial resistance, diabetes, and inflammations. Further in-depth investigations are urgently crucial to explore the importance of such medicinal plants in pharmaceutical production.
