Integrated extraction approach to increase the recovery of antioxidant compounds from Sida rhombifolia leaves

Intensified green-based extraction process as a circular economy approach to recover bioactive compounds from soursop seeds (Annona muricata L.)

“…Besides that, the effect of the high pressure of the system (at SFE and SWE processes) gives rise to a phenomenon called penetration, increasing the interaction between the matrix and solvent ( Chaves et al, 2020 ). It is noteworthy that the SWE process, if integrated with the SFE, allows the SFE to weaken cell walls from the solid phase, changing the characteristics of the plant matrix, enabling greater solubility of the compounds ( Ferro et al, 2019 ).…”

CARACTERIZAÇÃO ANATÔMICA E HISTOQUÍMICA DA LÂMINA FOLIAR DE SIDA rhombifolia L.

“…O principal alcaloide isolado no gênero é a efedrina (PRAKASH;VARMA;GHOSAL, 1981;CHATTERJEE;KUMAR;CHATTOPADHYAY, 2013). Dentre os compostos fenólicos, ácido ferúlico, isoquercetina, quempferol e coniferaldeído foram os componentes majoritários de extratos das folhas de S. rhombifolia (FERRO et al, 2019).…”

“…A atividade antidiabética e antioxidante foi demonstrada tanto para a planta (DHALWAL;DESHPANDE, PUROHIT;GHOSH;SUBUDHI;MISHRA, 2011;OLIVEIRA et al, 2012;CHATURVEDI;KWAPE, 2015;FERRO et al, 2019), quanto para o extrato aquoso da mistura de S. rhombifolia, Spilanthes africana e Portulaca oleracea (MOUKETTE et al, 2017).…”

Optimization of ultrasound-assisted extraction and the antioxidant activities of Sidaguri (Sida rhombifolia)

“…Sidaguri (Sida rhombifolia) is one of the famous Sida species among 200 others, belonging to the Malvaceae family. This species is widely distributed in tropical and subtropical regions and has been used to treat many diseases such as headaches, tuberculosis, diabetes, malaria, hemorrhoids, wounds, rheumatic, cardiac disease, diarrhea, and skin diseases for thousands of years (Ferro et al, 2019;Rohman et al, 2020). The studies of Sidaguri have been conducted for the past 50 years.…”

“…The studies of Sidaguri have been conducted for the past 50 years. Many studies reported that Sidaguri extract provides potent free radical scavenging activity toward 2,2′-diphenil-1-picrylhydrazyl (DPPH) radical, 2,2′-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS •+ ) radical, reducing power, superoxide scavenging activity, antibacterial activity, and anti-inflammatory activities (Ferro et al, 2019;Mah et al, 2017). These biological activities are manifestation of the secondary metabolites which are bioactive compounds produced by Sidaguri.…”
