Flavonoid content of mulberry leaves of 19 varieties of species, determined spectrophotometrically in terms of rutin equivalent, varied from 11.7 to 26.6 mg g−1 in spring leaves and 9.84 to 29.6 mg g−1 in autumn leaves. Fresh leaves gave more extract than air-dried or oven-dried ones. HPLC showed that mulberry leaves contain at least four flavonoid...
The paper investigates the release of phosphorus release of West Lake sediments at various alkaline levels and disturbances during a laboratory simulation. The distribution of phosphate forms in the sediments and the content of phosphorus in interstitial water were also determined.

... The total phenolics and flavonoids was extracted using 80% (v/v) methanol solution . After centrifuged at 10,000 × g at 4 • C, the supernatant was used to measure the levels of total phenolics and flavonoids using the Folin-Ciocalteu method and the method described by Jia et al. (1999), respectively. ASA was extracted from fresh leaves or roots using 5% (v:v) metaphosphoric acid, and the supernatant was then determined using the method of Zhou et al. (2020). ...
