Optimization of pressurized liquid extraction of Piper gaudichaudianum Kunth leaves

Analysis of alkaloids in Coptis chinensis Franch by accelerated solvent extraction combined with ultra performance liquid chromatographic analysis with photodiode array and tandem mass spectrometry detections

“…High temperature enhances extraction efficiency because it decreases the viscosity of the solvent, thus allowing better penetration of solvent molecules into the sample matrix. The use of ASE decreases the total extraction time, and improves extraction efficiency through the manipulation of parameters such as temperature, time, cycles and solvent [29][30][31]. Up to date, ASE has found only limited applications in TCM analysis, although the technique has been widely applied to the extraction of natural products [32][33][34][35].…”

Chemical composition of mate tea leaves (Ilex paraguariensis): A study of extraction methods

“…In this technique, short periods of time are required, and with small amounts of solvent compared to conventional extraction procedures. The process takes the advantage of increasing analyte solubility at temperatures well above the boiling points of common solvents [3,4], and provides a high level of automation [5]. For these reasons, the PLE technique has been extensively investigated for the extraction of essential oils from vegetable samples in recent years [5][6][7][8][9].…”

“…Several factors may affect the concentration of desired components in the extract such as temperature, sample to solvent ratio, flow rate, and particle size [10,11]. An important and interesting use of PLE is the extraction of chemical constituents from plant and herbal materials, where PLE appears to be the most effective sample preparation method [3,4,12].…”

Sequestration of prenylated benzoic acid and chromenes by Naupactus bipes (Coleoptera: Curculionidae) feeding on Piper gaudichaudianum (Piperaceae)

“…Piper gaudichaudianum Kunth, known as pariparoba, paripaioba, muta, iaborandi, and jaborandi, is one of the most widely spread species in the Brazilian Atlantic Forest, from Northeast to South, reaching Argentina and Paraguay (Péres et al 2006). Its wide occurrence can be associated with the production of a large number of tiny seeds coupled to an efficient dispersal process by bats (Mikich et al 2003).…”
