In this study, solvents of varying polarity were used to extract and separate the medium and high polarity compounds from the non-polar compounds of the resin.
This might be because the methanol water mixture has high polarity and thus has greater efficacy toward extraction of polar phytochemicals such as phenolics and flavonoids.
The CMC results indicate that asphaltenes with high polarity and low aromaticity have a high solubility in polar solvents such as nitrobenzene, whereas asphaltenes with low polarity and high aromaticity are more soluble in solvents with weak polarity, like toluene.
The result represented that extract using moderately polar solvent was more effective than low or high polarity solvents to get higher content of phenolic and flavonoids.
TPU, like Ninjatek Cheetah, is a copolymer composed of both low and high polarity chain segments.
Ergostanes have high polarity than lanostanes, and their log P values were between 3 and 4.7.
Due to the high polarity of water, ZnO nanoparticles usually agglomerate immediately and form larger particles.
The high polarity of the nanosized clusters causes the properties of excitation-dependent [15, 19, 31].
Such absorption generates high polarity and the low-reactivity remains as on the individual pristine cases.
As the results, the high-polarity compounds such as scopoletin (1) and scoparone (2) were separated, while the low-polarity compounds were developed as one main band in the first run because of the high polarity of mobile phase.
The high polarity of nanosized cluster and the sp2-carbon networks can be responsible for these phenomena.
