Loxophlebal A, a new antibacterial formylated phloroglucinol was isolated from the mother liquor obtained after separation of sideroxylonals from the chloroform-methanol extract of leaves of Eucalyptus loxophleba ssp lissophloia. The structure of loxophlebal A was determined to be 3-desformyl sideroxylonal A by spectroscopic methods including 1D- and 2D-NMR. The stereochemistry of loxophlebal A...

Natural dyes are gaining interest due their expected low risk to human health and to the environment. In this study, the wash fastness of a natural coloring matter from the liquid waste produced in the steam treatment of eucalyptus wood in textile fabrics was investigated. Specifically, eucalyptus wood extract was used to dye cotton, nylon and wool in an exhaust dyeing process without the addit...

The aim of this study is to determine the effect of the aqueous extract of the leaves of Eucalyptus globules on blood glucose level in fasted rats, and to find a new medical adjunct to anti-diabetes drugs. The aqueous extract of Eucalyptus was administered in various doses (150-400 mg/kg) orally. Blood glucose level was checked 2-6 h after treatment. The study showed that oral administration of...

Experiments were conducted to study the bioefficacies of different plant/weed derivatives that affect the development of the pulse beetle, Callosobruchus maculates F. (Coleoptera: Bruchidae) fed on black gram, Vigna mungo, seeds. Plant extracts, powder, ash and oil from nishinda (Vitex negundo L.), eucalyptus (Eucalyptus globules Labill.), bankalmi (Ipomoea sepiaria K.), neem (Azadirachta indic...

Background: Bacillus subtillis bacteria can cause meningitis, endocarditis, and eye infections, while Enterococcus meningitis in neonates endocarditis adults. Therefore, it is important to use hand sanitiser avoid bacterial infections. Eucalyptus an essential oil-producing plant that inhibit growth kill with its compounds, namely linalool pinocarveol. Purpose: To make a good eucalyptus oil test...

The leaves of Eucalyptus robusta Smith (Myrtaceae) are used in China to prepare the anti-malari­ al traditional medicine “Da Ye An” [1], Previous work on the extract of the leaves has yielded the bisphloroglucinol robustaol [21 as well as the robustadials A and B [3], The known phenols euglobal la, and Ia2, originally reported from E. globulus [4], were also isolated [3]. In a broad screening f...

To evaluate the effect of eucalyptus, sappan, and cinnamon leaf bark extract on percentage S. mutans biofilm formation. The test group was divided into a negative control (1% Dimethyl sulfoxide), treatment (eucalyptus, leaves at concentrations 50%, 25%, 12.5%, respectively), positive (0.2% chlorhexidine). Each concentration barks extract, Brain Heart Infusion Broth (BHI-B), bacteria according t...

the aim of this study was to investigate the allelopathic effects of eucalyptus camaldulensis on germination and early seedling growth of festuca arundinacea under laboratory condition in order to determine the effect of pretreatments on decreasing the destructive effects of allelopathic compounds. the chemical stimulators used in this study included 3 levels of gibberellic acid, 3 levels of sa...

OBJECTIVES To investigate Eucalyptus (gum tree) pollen allergy in children in relation to geography, particularly vegetation, and its relationship to asthma. METHODS Males (n = 180) and females (n = 200) aged 9 to 14 participated. Some were healthy (asymptomatic), some had asthma, and some had other symptoms associated with atopy. School students were from three urban coastal schools and one ...

Tuberose (Polianthes tuberosa) is one of the most important cut flowers with fragrant buds. To prolong vase life of tuberose, proper preservative solution applying is necessary. For this purpose, two types of chemical and natural treatments were used. Applied treatments were benzyladenine (50, 100, and 150 mg l-1), the extracts of rosemary and Eucalyptus (12, 25 and 50%) and sour orange fruit e...
