Pomegranate peel is a rich source of phenolic compounds (such as punicalagin and hydroxybenzoic acids). However, the content of such bioactive compounds in the peel extract can be affected by extraction type and condition. It was hypothesized that the optimization of a pulsed ultrasound-assisted extraction (PUAE) technique could result in the pomegranate peel extract with higher yield and antio...

During recent years, microwave irradiation has been extensively used for performing green organic synthesis. The aim of this study was to synthesize, through a microwave-assisted irradiation process, a natural surfactant with O/W emulsifying properties. Our attention was focused on polyglycerol esters of fatty acids that are biocompatible and biodegradable non-ionic surfactants widely used in f...

since solid-phase and liquid-phase microextraction (spme and lpme) were introduced, as effective solvent-free methods, many efforts have been made to improve their modes and applications. however, due to limitations with sensitivity and efficiency, researchers have focused on improving the performance of their basic primary modes. in this way, in recent years, different methods such as ultrason...

In the microwave-assisted alcoholysis of dialkyl phenylphosphonates performed in presence suitable ionic liquids, such as [bmim][BF<sub>4</sub>] or [bmim][PF<sub>6</sub>], affording phosphonate with mixed alkoxy groups and fully transesterified product, fission function to ester-acid diacid moiety was inevitable. Moreover, [emim][HSO<sub>4</sub>], reaction co...

Olive leaves are considered to have great potential as natural sources of antioxidants and phenolic compounds. In this study, dried olive were extracted using four different solvents (water, methanol, ethanol, 80:20(v/v) methanol-water) with ultrasonic-assisted extraction. The biochemical (total phenolics flavonoids, total protein, free amino acids, soluble, reducing sugars) antioxidant activit...

Objective: The study aimed to evaluate the physicochemical properties and nutrition of Moringa leaf extract. In addition, preliminary for preparation extract-loaded phytosomes a supplement. Methods: Extraction made using microwave-assisted extraction, followed by evaluation proximate analysis (water, total ash, acid-insoluble ash contents, residual n-hexane), phytochemical screening, such as cr...

The Asteraceae is a large family, rich in ornamental, economical, and medicinally valuable plants. current study involves the analytical pharmacological assessment of methanolic extracts three less investigated plants, namely Echinops ritro, Centaurea deflexa, Tripleurospermum decipiens, obtained by different extraction methodologies viz. maceration (MAC), ultrasound-assisted (UAE), homogenizer...

background: although heterotopic gestation is common in assisted reproductive techniques, it is very rare in natural conception and clomiphene induced pregnancy. diagnosis and appropriate intervention of heterotopic pregnancy requires a high index of suspicious. case: in this paper a case of heterotopic pregnancy in a 30-year old woman with hemoperitoneum from ruptured tubal pregnancy with live...
