Anxiolytic Effect of Citrus aurantium L. on Patients with Chronic Myeloid Leukemia
The bone marrow aspiration procedure is used in hematological diseases and consists of a painful, invasive procedure causing anxiety‐associated symptoms. The present study assessed the effect of Citrus aurantium L. essential oil on the treatment of anxiety, in the moment that precedes the collection of medullary material in patients with chronic myeloid leukemia (CML). Volunteers from both sexes were divided into groups receiving either the C. aurantium essential oil through inhalation, diazepam (10 mg), or the placebo. The evaluation was performed through psychometric scales [State‐Trait Anxiety Inventory (STAI)] an...

Optimization of microwave assisted extraction of pectin from sour orange peel and its physicochemical properties
Publication date: 20 April 2016 Source:Carbohydrate Polymers, Volume 140 Author(s): Seyed Saeid Hosseini, Faramarz Khodaiyan, Mohammad Saeid Yarmand Microwave assisted extraction technique was used to extract pectin from sour orange peel. Box–Behnken design was used to study the effect of irradiation time, microwave power and pH on the yield and degree of esterification (DE) of pectin. The results showed that the optimum conditions for the highest yield of pectin (29.1%) were obtained at pH of 1.50, microwave power of 700W, and irradiation time of 3min. DE values of pectin ranged from 1.7% to 37.5%, indicating ...

A new phenolic glycoside and two new monoterpenoid furocoumarins from Aurantii Fructus Immaturus.
Abstract
A new phenolic glycoside, citrauranoside A (1), and two new monoterpenoid furocoumarins, citraurancoumarin A (2) and citraurancoumarin B (3), along with four known compounds (4-7) were isolated from the young fruit of Citrus aurantium L. The structures were elucidated by their comprehensive analysis including 1D, 2DNMR, IR and mass spectra.

The effects of cognitive reappraisal following retrieval-procedures designed to destabilize alcohol memories in high-risk drinkers
Conclusions
This study provides partial preliminary support for the idea that a common psychotherapeutic strategy used in the context of putative memory retrieval-destabilization can alter accessibility of alcohol semantic networks. Further research delineating the necessary and sufficient requirements for producing alterations in alcohol memory performance based on memory destabilization is still required.

Absence of furanocoumarins in Advantra Z® (Citrus aurantium, bitter orange) extracts.
This study examined the furanocoumarin content of four standardized bitter orange extracts (Advantra Z®) by liquid chromatography-mass spectroscopy. The results indicated that the total furanocoumarin content of each of the four extracts was less than 20 μg/g, amounts insufficient to exert significant effects on the metabolism of susceptible drugs in human subjects at the doses commonly used for these extracts.

Aqueous extraction of pectin from sour orange peel and its preliminary physicochemical properties.
Abstract
Sour orange peel, a by-product of the fruit juice industry, was used as a source of pectin. The effects of temperature (75-95°C), time (30-90min), and liquid-solid ratio (20-40 v/w) were investigated on yield, methoxylation degree (DE), and galacturonic acid content using a Box-Behnken design and response surface methodology. The highest extraction yield (17.95±0.3%) was obtained at temperature of 95°C, time of 90min, and liquid-solid ratio of 25 (v/w). The DE values for the pectin ranged from 17% to 30.5%, indicating that the pectin was low in methoxyle. The emulsifying activity of pectin extr...

Molecules, Vol. 20, Pages 18620-18660: A Systematic Review of the Anxiolytic-Like Effects of Essential Oils in Animal Models
The clinical efficacy of standardized essential oils (such as Lavender officinalis), in treating anxiety disorders strongly suggests that these natural products are an important candidate source for new anxiolytic drugs. A systematic review of essential oils, their bioactive constituents, and anxiolytic-like activity is conducted. The essential oil with the best profile is Lavendula angustifolia, which has already been tested in controlled clinical trials with positive results. Citrus aurantium using different routes of administration also showed significant effects in several animal models, and was corroborated by differ...

Flavonoids of Korean Citrus aurantium L. Induce Apoptosis via Intrinsic Pathway in Human Hepatoblastoma HepG2 Cells
Korean Citrus aurantium L. has long been used as a medicinal herb for its anti‐inflammatory, antioxidant, and anticancer properties. The present study investigates the anticancer role of flavonoids extracted from C. aurantium on human hepatoblastoma cell, HepG2. The Citrus flavonoids inhibit the proliferation of HepG2 cells in a dose‐dependent manner. This result was consistent with the in vivo xenograft results. Apoptosis was detected by cell morphology, cell cycle analysis, and immunoblot. Flavonoids decreased the level of pAkt and other downstream targets of phosphoinositide‐3‐kinase/Akt pathway – P‐4EBP1 ...

GC-FID/MS Profiling of Supercritical CO2 Extracts of Peels from Citrus aurantium, C. sinensis cv. Washington navel, C. sinensis cv. Tarocco and C. sinensis cv. Doppio Sanguigno from Dubrovnik Area (Croatia).
Authors: Jerković I, Drulžić J, Marijanović Z, Gugić M, Jokić S, Roje M
Abstract
The peels of Citrus aurantium L. and Citrus sinensis Osbeck cultivars from the Dubrovnik region (south Croatia) were extracted by supercritical CO2 at 40 degrees C and 10 MPa at 1.76 kg/h to obtain enriched extracts in comparison with simple pressing of the peels. The extracts were analyzed in detail by gas chromatography and mass spectrometry (GC-FID/MS). Relevant similarities among the peel oil compositions of C. aurantium and C. sinensis cultivars were found with limonene predominance (up to 54.3%). The principal oxyg...
