The hydrate-water fractionation value depends on, among other things, the location and temperature.
This may result from the uncertainty in the hydrate-water fractionation value of δ 18O, but we do not discuss this topic here.
In addition, the zoisite-water fractionation factor constrained by mineral-pair equations is around unity (Matthews et al. 1983), causing no 18O/16O fractionation.
Following fractionation, the water fractions (W) from both varieties showed higher phenolic content than the ethyl acetate fractions (E).
The authors outlined a number of assumptions and derived a quartz-water fractionation-temperature relationship for low temperatures.
As such, the temperature estimates for this and previous studies are imperceptibly impacted by the new quartz-water fractionation-temperature relationship for low temperature developed by Sharp et al. [66].
This new quartz-water fractionation-relationship may yield a 1 or 2 °C decrease in temperature estimates relative to the original temperature extrapolations made by Knauth and Epstein [45].
If future work on low-temperature, quartz-water fractionation-temperature relationships yield significantly different temperature estimates, then the temperatures derived from our approach will need to be adjusted accordingly.
The crude dried methanol extract was suspended in water and subjected to fractionation using chloroform, ethyl acetate and butanol to obtain chloroform, ethyl acetate, butanol, and water fractions.
angustifolia (SFC) and its fractionation led to higher flavonoids in the ethyl acetate fraction (SFE) compared to the water fraction (SFW).
