[Constituents of Lilium candidum L. and their antioxidative activity].

The paper deals with the separation and identification of a flavonoid glycoside from the petals of Lilium candidum L. and the antioxidative properties of the ethanolic extract of the flowers and selected compounds isolated from this species. The isolated flavonoid glycoside was identified as isorhamnetin-3-O-rutinoside by acid hydrolysis, TLC comparison with authentic samples, and UV and mass spectra.

[Flavonoids--main constituents of the leaves of Holodiscus discolor (Pursh) Maxim].

The paper deals with the isolation and identification of constituents of the leaves of Holodiscus discolor (Pursh) Maxim. (Rosaceae). Three flavonoid glycosides of flavonol type were isolated from the methanolic extract: kaempferol-3-O-rhamnoside, quercetin-3-O-glucoside (isoquercitrin) and quercetin-3-O-rhamnoside (quercitrin).

[Anti-yeast activity of ethanol extracts of Lilium candidum L].

The paper deals with anti-yeast activity of ethanolic extracts from the flowers and bulbs of Lilium candidum L., Liliaceae, as well as some compounds isolated from these extracts. Several different methods were used for the determination of anti-yeast activity: Lowry method of protein determination, dilution and cultivation method.

[Constituents of the leaves of Holodiscus discolor (Pursh) Maxim].

The paper deals with the isolation of constituents from light petrol and methanol extracts of the leaves of Holodiscus discolor (PURSH) MAXIM., Rosaceae. beta-sitosterol and taraxasterol were isolated from the light petrol extract, luteolin-7-O-glucoside was isolated from the methanol extract.

Potential carcinogenic and inhibitory activity of compounds isolated from Lilium candidum L.

This paper deals with determination of potential carcinogenic and inhibitory activity of 10 compounds isolated from the ethanolic extract of Lilium candidum L. perfonned by DC polarography. The series of investigated compounds consisted of two spirostanol saponins, two pyroline derivatives, jatropham and its glucoside, flavonol kaempferol, 2-fenylethyl-alpha-L-arabinopyranosyl-(1-->6)-beta-D-glucopyranoside, 2-phenylethylpalmitate and methylsuccinic acid.
