Tomsk. Univ.: Tomsk, USSR. (Russian) 1975. CODEN: 35BFAU. DOCUMENT TYPE: Conference CA Section: 3 (Biochemical Interactions) Of 14 phenolic compds. isolated by 2-dimensional paper chromatog. from 4 species of Sedum, esculetin [305-01-1] and the glycoside of gossypetin [489-35-0] were active against Candida, Anthracoides, Escherichia coli, and Staphylococcus 209 in vitro. Myricetin [529-44-2] and gallic acid [149-91-7] inhibited only Candida growth. .

DOCUMENT TYPE: Journal CA Section: 64 (Pharmaceutical Analysis) The chromatog. behavior of esculin [531-75-9], syringin [118-34-3], fraxin [524-30-1] and esculetin [305-01-1] was studied by reversed-phase high performance liq. chromatog. These compds. in an ethanolic ext. of Chin Pie (the bark of F. chinensis) can be easily sepd. 524-30-1 and 531-75-9 which are cas registry numbers are also used here. on an ODS column (25 cm ′ 5 mm) with MeOH-H2O-AcOH (:0.4) as eluant. Std. curves were linear in the range 1.02-4.08, 0.612-2.45, 0.159-0.636 and 0.067-0.268 mg for the 4 compds., resp. The proposed method is simple, rapid and more sensitive than the TLC-densitometric method. The relative std. deviation was 2.4%. .
