Opis:: The fraction of sterol acetates from the inflorescences of Hieracium pilosella has been isolated in the typical way from petroleum ether extract. By means of the weight method the total amount of sterols was determined (0.2659%). The mixtures of sterol acetates and free sterols were investigated using GC-MS techniques. The occurrence of about 18 sterols has been observed. Cholesterol, cholest-8(14)-en-3b-ol, cholesta-5.7-dien-3b-ol, cholest-7-en-3b-ol, ergosta-5.24-dien-3b-ol, campesterol, stigmasterol, b-sitosterol, fucosterol, 5a-stigmast-7-en-3a-ol were identified. The probable structures of lophenol, isofucosterol, 5a-stigmasta-7.24-dien-3b-ol, lanosta-9(11).24-dien-3b-ol and 24-ethylidene lophenol were stated on the basis of literature data. The last 4 sterols occur in a vestigial quantity, which made its identification impossible. Sitos erol and cholesterol are remarkably dominating sterols in the fraction.

Tytuł:: A new stand of Hieracium pilosum Schleich. ex Froelich (Asteraceae) in the Polish Tatra Mountains

Opis:: A new stand of H. pilosum, a species not reported before from the territory of Poland, was found in the Polish Western Tatra Mts. It grows in numerous stands on limestone rocks on the slopes of Upłaziańska Kopka, at ca. 1400 m a.s.l. Moreover, typical form of this species, collected in the Polish Western Tatra Mts, was also found in herbaria of KRA and KRAM. These data indicate that H. pilosum is a widespread species in the described region but it was unrecognized from H. villosum so far.

Opis:: Typical chromatographic methods were successfully applied to isolate nine flavonoid compounds and two coumarin glycosides from the inflorescences and the herb of Hieracium pilosella L. Repeated column chromatography, occasionally paper chromatography and recrystallization made the separation of three flavonoid aglycones and six glycosides - possible. Coumarin glycosides were isolated by preparative thin layer chromatography. Subsequent UV, NMR and MS analyses have led to identification of the following flavonoid derivatives: known for the species - apigenin, luteolin, luteolin 7-O- ß-glucopyranoside, luteolin 4’-O-ß-glucopyranoside, isoetin 7-O-ß- -glucopyranoside, isoetin 4’-O-ß-glucuronide and new for the species – kaempferol 3-methyl ether and apigenin 7-O-ß-glucopyranoside. Third isoetin glycoside contained two different sugar moieties: xylose and glucose, probably attached to the hydroxyl groups at C-4’ or C-4’ and C-2’(or 5’) of an aglycone. Umbelliferone 7-O-ß-glucopyranoside (skimmin) and new for the genus Hieracium esculetin 7-O-ß-glucopyranoside (cichoriin) were determined by NMR and MS methods.

Opis:: The analysis of the fractions of free and bound, liberated by hydrolysis, phenolic acids in the inflorescences and rhizomes with roots of Hieracium pilosella L. was conducted by 2D-TLC and RP-HPLC methods. In the inflorescences fourteen phenolic acids were found: chlorogenic, gallic, protocatechuic, homoprotocatechuic, caffeic, gentisic, p-hydroxyphenylacetic, p-hydroxybenzoic, m-hydroxybenzoic, p-coumaric, syringic, vanillic, ferulic and salicylic. In the rhizomes with roots nine phenolic acids were identified: chlorogenic, gallic, homoprotocatechuic, caffeic, gentisic, p- hydroxyphenylacetic, p-hydroxybenzoic, syringic and vanillic. By means of the RP-HPLC method the contents of major acids were estimated which ranged from 0.01 mg% up to 139.50 mg%. Caffeic acid is the remarkably dominating constituent of both plant materials. Phenolic compounds may contribute to invasiveness and medicinal properties of this species.
