The volatile constituents of the essential oils of the peel, flower (neroli) and leaves (petitgrain) of bitter orange (Citrus aurantium L.) growing in Greece were studied by GC-MS. The analytical procedures enabled the quantitative determination of 31 components. More specifically, the components of the essential oils identified were: twelve in the peel, twenty-six in the flowers, and twenty an...

Isolates of citrus exocortis viroid (CEV) from a single sweet orange citrus source have been selected by sequential passage through the alternative hosts citron, Gynura aurantiaca, a hybrid tomato Lycopersicon esculentum x L. peruvianum, and from disorganized callus culture of the hybrid tomato. The distinctions in symptom expression, titre and electrophoretic mobility among the CEV isolates, o...

Changes in gene expression of Mexican lime plants in response to infection with a severe (T305) or a mild (T385) isolate of Citrus tristeza virus (CTV) were analyzed using a cDNA microarray containing 12,672 probes to 6875 different citrus genes. Statistically significant (P<0.01) expression changes of 334 genes were detected in response to infection with isolate T305, whereas infection with T3...

A total of 39 aroma compounds were detected in the essential oil of Citrus nagato-yuzukichi Tanaka (nagato-yuzukichi) by gas chromatography-mass spectrometry (GC-MS). The essential oil was characterized by a high percentage of monoterpene hydrocarbons (12 components, 90.52%). The composition pattern of essential oil in C. nagato-yuzukichi was fairly similar to that of Citrus sudachi Hort. ex Sh...

Jeruk nipis (Citrus aurantifolia S.) merupakan salah satu tanaman obat tradisional yang digunakan secara luas untuk berbagai penyakit termasuk infeksi. Penelitian ini bertujuan menguji aktivitas ekstrak etanol 70% dan 96% daun Citrus terhadap mikroba penyebab infeksi pada manusia, antara lain Staphylococcus aureus, Salmonella typhi, Escherichia coli, Candida albicans in vitro.

The aim of this research is to comparatively study the phytochemical and antimicrobial properties of Bryophyllum pinnatum and Citrus aurantifolia leaf extracts and their synergy. Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, and Pseudomonas aeruginosa, Aspergillus niger, Mucor mucedo, Penicillium notatum and Candida albicans, were used as test organisms and the antimicrobial a...

The Lime oil of Citrus aurantifolia was microencapsulated by coacervation technique employing gelatine and alginates as the shells, calcium chloride cross linker. Optimization core/shell ratio, speed temperature stirring carried out. Structure shape microcapsules were characterized particle size analyzer (PSA) scanning electron microscope (SEM) respectively. properties such as, yield, distribut...
