Optimal defense (OD) theory predicts that within a plant, tissues are defended in proportion to their fitness value and risk of predation. The fitness value of leaves varies greatly and leaves are protected by jasmonate (JA)-inducible defenses. Flowers are vehicles of Darwinian fitness in flowering plants and are attacked by herbivores and pathogens, but how they are defended is rarely investig...

The change of essential oil ratios and components five different basil genotypes harvested at times (00:00, 06:00, 12:00, 18:00) in day was investigated. Plants were grown under the field conditions oils plants extracted by hydro-distillation method. Identification performed GC-MS. It G5 genotype that had highest content all plant parts, regardless time day. (2.8%) obtained from dry leaves samp...

Fumagillin (1), a meroterpenoid from Aspergillus fumigatus, is known for its antiangiogenic activity due to binding to human methionine aminopeptidase 2. 1 has a highly oxygenated structure containing a penta-substituted cyclohexane that is generated by oxidative cleavage of the bicyclic sesquiterpene β-trans-bergamotene. The chemical nature, order, and biochemical mechanism of all the oxygenat...

The chemical compositions of essential oils obtained from Ocimum basilicum var. thyrsiflora (1.39 % dry weight) and Ocimum basilicum (0.61 %) were analyzed by GC–MS. Seventy-three constituents representing 99.64 % of the chromatographic peak area were obtained in the O. basilicum var. thyrsiflora oil, whereas 80 constituents representing 91.11 % observed in the essential oil of O. basilicum wer...

There have been efforts to overcome the problem in treatment of cancer using medicinal plants. It has been shown that Citrus essential oil of contains different terpens with antitumor activities. In this study we sought to determine the cytotoxicity of essential oils of Iranian Citrus limon (L.), C. medica (L.), C. sinsensis (L.) peels on cancer cell lines. Essential oils were prepared by hydr...
