Pharmaco-constituents of Taraxacum hallaisanensis(I) -Phenolic Compounds from Aerial Part of Taraxacum hallaisanensis-

좀민들레의 약효 성분(I) -좀민들레 지상부의 Phenol 성분-

For the investigation of medicinal resources from Taraxacum species, the studies were carried out to evaluate the pharmaco-constituents in the aerial part of Taroxacum hallaisanensis, an endemic plant of Korea. From BuOH fraction of the MeOH extract, compound 1 (protocatechuic acid, $C_7H_6O_4,\;3,4-dihydroxy\;benzoic\;acid)$, compound 2 $[C_{22}H_{31}O_6,\;luteolin-7-O-{\alpha}-_L-rhamnopyranosyl(1{\rightarrow}6)-{\beta}-_D-glucopyranoside]$, and compound 3 $[C_{15}H_{20}O_6,\;luteolin-7-O-{\beta}-_D-glucopyranoside]$ were isolated by column chromatographic separation using polyamide and ODS-gel. The structures were elucidated by means of physico-chemical evidences($^1H-NMR,\;{12}^C-NMR$, IR, EI-Mass, FAB-Mass and GC).
