-Mangiferin is a natural xantone extensively distributed in higher plants showing different pharmacological properties. In the present study, an ultrasonicassisted extraction (UAE) method was evaluated for obtain mangiferin from Mangifera indica L. (c.v Mango Macho) leaves. Differents extraction parameters were optimized using a response surface methodology and the best conditions reached were at 47% ethanol concentration, a liquid-to-solid ratio 47:1, and an extraction time of 63min. under ultrasound irradiation of 150W. In these circumstances, the yield of mangiferin was 24.15±0.015mg/g. For first time, was evaluated the ultrasound assited extraction to higher frecuency and the value of the yield reached was 6.38± 0.062mg/g. Comparison of UAE of mangiferin respect to microwave and aggited tank was realized and the yield obtained by UAE was inferior, however the ultrasonic time was minor respect to conventional extraction technique. The ultrasonic-assisted extraction is an alternative method to use for the extraction of mangiferin from Cuban mangos.

“…Many of these properties are due to antioxidant activity which can be determined by different mechanisms such as free radical scavenging, electron or hydrogen atom donation, or metal cation chelation (Balasundram et al, 2006). Efficient extraction techniques are required for the isolation and identification of polyphenolic compounds (Nkhili et al, 2009;Bart, 2011;Mustafa and Turner, 2011;Petigny et al, 2013;Rój, 2014). Solid-liquid extraction under controlled experimental conditions is important for the reproducibility of the products and the preservation of their bioactivity (Tsibranska and Tylkowski, 2016).…”

The use of medicinal plants has been well documented for the past several decades. Plants from the Lavender genus are used for culinary purposes, but also as a part of herbal medicine, owing its benefits to essential oils and bioactive compounds. A detailed description of the extraction process dynamics is required to obtain the highest possible amount of bioactive compounds from lavender. In this study, a solid-liquid extraction of lavender flowers, using water as solvent, was performed. Total polyphenols, dry matter, conductivity, and total dissolved solids were determined in regular time intervals and experimental data was further used for mathematical modelling. Peleg's, Page's, and the logarithmic model were applied in order to describe the kinetics of bioactive compounds in lavender during solid-liquid extraction. The initial extraction rate and extraction capacity were determined for three different extraction temperatures; T = 40, 60, and 80 °C. The obtained results indicated that the initial extraction rate and the extraction capacity were the highest at T = 80 °C. The adequacy of the applied mathematical models was estimated based on R 2 and SRMSE values, which indicated that the most adequate model for solid-liquid extraction of lavender was the Peleg's model (R 2 = 0.996, for total polyphenols at T = 40 ºC and R 2 = 0.975 for dry matter at T = 60 °C, respectively).

“…Implosion of cavitation bubbles on the surface of plant material generates strong liquid microjets which could improve solvent penetration into the plant material and enhance the diffusion process, resulting in an increase in the TES yield [13,15]. The enhancement of extraction efficiency with an increase in the ultrasound power was also reported for UAE of fresh rosemary [37] and boldo leaves [38].…”

The effects of ultrasound power and frequency on the yield of total extractive substances (TES), total phenolic content (TPC), total flavonoid content (TFC) and antioxidant activity (AOA) of fresh houseleek leaves extracts obtained by direct ultrasound-assisted extraction (DUAE) were studied. Preliminary extraction of plant material was performed using methanol, acetone and 2-propanol by Soxhlet extraction. It was found that maximum TES yield could be obtained by methanol extraction (2.91±0.02), followed by acetone and 2-propanol with a TES yield of 2.32±0.01 and 2.01±0.03 g per 100 g of fresh plant material, respectively. In the fresh houseleek leaves extracts obtained by DUAE and methanol as the chosen solvent, TPC, TFC and AOA were in the ranges of: 40.5-85.9 mg gallic acid/g dry extract, 12.7-19.3 mg rutin/g dry extract and 24.6-108.2µg/ml, respectively. The results showed that the increase in the ultrasound power and extraction time have positive and significant (p < 0.05) effects on the TPC, TFC and AOA, while the increase in the ultrasound frequency leads to a decrease in the TPC, TFC and AOA of the extracts.
