The present work investigates the effect of ripening stage on the chemical composition of essential oil extracted from peel of four citrus: bitter orange (Citrus aurantium), lemon (Citrus limon), orange maltaise (Citrus sinensis), and mandarin (Citrus reticulate) and on their antibacterial activity. Essential oils yields varied during ripening from 0.46 to 2.70%, where mandarin was found to be ...

Bitter orange (Citrus aurantium) extract and its primary protoalkaloid p-synephrine are used widely in weight loss/weight management and sports performance products. Because of structural similarities, the pharmacological effects of p-synephrine are widely assumed to be similar to those of ephedrine, m-synephrine (phenylephrine), and endogenous amine neurotransmitters as norepinephrine and epin...

Aerial parts of Citrus aurantium L. were subjected to headspace (HS) and hydro-distillation (HD) techniques after drying, and then headspace volatiles and the essential oil were analyzed by GC/MS. Results of GC/MS analysis led to identification seventeen (99.8%) and sixteen (99.9%) constituents in samples extracted by HS methods in leaf and flower, respectively. (E)-β-ocimene (2.5%), Linalool (...

in this study, the effect of four citrus rootstocks {sour orange (citrus aurantium), bakraeii (c. reticulata × c. aurantium, mexican lime (c. aurantifolia) and volkamerlemon (c. volkameriana)} on orlando tangelo leaf chlorophyll content and mineral element concentrations (n, p, k, ca, na, mg, fe, zn, mn, cl, cu, and b) have been evaluated in completely randomized design with four replications. ...

This article is a literature review dealing with the various ways that tree ring data can be used for analysis of rockfall activity. Typically, this type of research has been done using historical archives, lichenometric studies, or through frequency-volume statistics. The overall purpose of this paper is to present a literature review study about the current state of tree ring research as it p...

Introduction: Epidemiological studies suggest that dietary limonoids and phytosterols offer protection from some types of cancers (1). In the present study, cancer preventive components from sour orange (Citrus aurantium L.) were isolated and identified for the first time. Isolated compounds were tested for the inhibition of human colon cancer cells (HT-29) proliferation, apoptosis. Methods: So...
