Supramolecular solvent-based ultrasound-assisted extraction of fangchinoline and tetrandrine from the roots of Stephaniae tetrandrae A supramolecular solvent (SUPRAS) based ultrasound-assisted extraction method was developed for the extraction of fangchinoline and tetrandrine from Radix Stephaniae tetrandrae. SUPRASs were prepared in aqueous solutions containing hexafluorobutanol (HFB) and alkanols for the first time.

Chlorophyll and Carotenoid Measurement Extraction and measurement of chlorophyll and carotenoid was conducted according to previously reported methods.[55] All steps were performed at 4 °C in the dark. ≈0.6 g of kiwifruit flesh powder was weighed and extracted with 2 mL 80% acetone (v/v) for 1 h. The mixture was then centrifuged at 12 000 g for 10 mi and the supernatants were transferred to a new tube stored in ice.
