Chemical Composition of the Essential Oils of Four Cultivated Eucalyptus Species in Iran as Medicinal Plants (E. microtheca, E. spathulata, E. largiflorens and E. torquata)
The leaves of four cultivated Eucalyptus species, Eucalyptus microtheca var. Microtheca F. Muell., Eucalyptus spathulata, Eucalyptus largiflorens and Eucalyptus torquata were collected in spring from Kashan and Isfahan provinces (central region of Iran). After drying the plant materials in shade, their essential oils were obtained by hydro-distillation. The oils were analyzed by capillary gas c...

متن کاملThe phytochemistry and ethnobotany of the southern African genus Eucomis (Hyacinthaceae: Hyacinthoideae)
The endemic African genus Eucomis (Hyacinthaceae) has long been one of the most highly regarded sources of ethnomedicines in southern Africa, attracting the attentions of toxicologists, pharmacologists and phytochemists. This chapter reviews the ethnobotany of this small group of fourteen described taxa (ten species), and the known phytochemistry. Six taxa (five species) have been recorded used...
متن کاملOn weakly e*-open and weakly e*-closed Functions
The aim of this paper is to introduce and study two new classes of functions called weakly $e^{*}$-open functions and weakly $e^{*}$-closed functions via the concept of $e^{*}$-open set defined by Ekici cite{erd1}. The notions of weakly $e^{*}$-open and weakly $e^{*}$-closed functions are weaker than the notions of weakly $beta$-open and weakly $beta$-closed functions defined by Caldas and Nava...
