modified bubble column extraction with ultrasonic bath (bce-ub) method was used to extract atropine from the stem and leaves of atropa belladonna. optimum condition were obtained with kamada solvent which was chloroform-methanol-ammonia 15:15:1(v/v/v) as extraction solvent, the particle size of  less than  350 µm, an extraction time of 23.95 min, a liquor to material ratio of 15.08 ml/g and  an...

This work is focused on the preparation of an innovative gluten-free (GF) bread with remarkable softness and antioxidant features over time. To overcome technological inconveniences related to removal gluten from bread, kefir beverage fortified vegetable extracts employed as a functional ingredient in bread-making process. In this context, carob (Ceratonia siliqua L.) leaves represent outstandi...

BACKGROUND The present work was designed to appraise how different extraction solvents and techniques affect the extractability of antioxidant and antimicrobial components from Lantana camara (L. camard) flowers. MATERIAL AND METHODS Four extraction solvents including 100% methanol, 80% methanol, 100% ethanol and 80% ethanol coupled with three extraction techniques namely stirring, microwave-...

Curcuma, a major Zingiberaceae genus, contains approximately 110 species throughout the Asia-Pacific region. The present work aimed to study two Indian curcuma species, Curcuma caesia Roxb. and angustifolia Roxb., whose rhizomes are extracted using ultrasound-assisted extraction (UAE) with chloroform solvent. extracts subjected phytochemical screening analysed employing gas chromatography-mass ...

The essential oil (EO) from dried ground powder leaves and stems of Thymua danesis was extracted using hydrodistillation (HD), ohmic extraction (OE), ultrasound-assisted HD and ultrasound-assisted OE methods. Then, the antioxidant, antimicrobial, and sensory properties of the EO were investigated both in vitro and in food systems. Thyme EO extracted by ultrasound-assisted HD method had promisin...

Various extraction techniques were applied in the extraction of the biologically active constituents. The methods employed were traditional maceration extraction, microwave-assisted extraction(MAE), and ultrasound extraction (UE). Compared to the maceration extraction, MAE and UE methods provided high extraction yield, requiring short time frames and less labour. Microwave irradiation is a prov...

Microwave-assisted extraction of pectin from lemon peels by using ionic liquid as alternative solvent was investigated. The extracted pectin was detected by Fourier transform infrared spectra. The extraction conditions were optimized through the different experiments in conjunction with the response surface methodology. A pectin yield of 24.68 % was obtained under the optimal parameters: the ex...

BACKGROUND Rattan tea is a medicinal plant that has been used for many years for the treatment of inflammation, fatty liver, tumor, diabetes, and hyperlipidemia. OBJECTIVE A green and novel approach based on surfactant-mediated, ultrasonic-assisted extraction (SM-UAE) was developed for the extraction of antioxidant polyphenols from Rattan tea. A nonionic surfactant Tween-80 was selected as ex...

Microwave assisted extraction (MAE) was investigated for the of total saponins compounds from starfish Echinaster sepositus. In order to achieve optimization microwave and determine influence each operational variable (the solvent concentration (X1), irradiation time (X2), power (X3), liquid-solid ratio (X4)) on saponins, response surface methodology (RSM) coupled with a Box–Behnken design (BBD...

Curcumin is a natural bioactive compound originated from the rhizomes of turmeric (Curcuma longa L.). This study was performed to investigate formic acid and microwave assisted extraction of curcumin from turmeric (Curcuma longa L.). In order to enhance the curcumin extraction, different parameters such as particle size, effect of pretreatment with water, radiation intensity and type of solvent...
