Dactylicapnos scandens (D. Don) Hutch (Papaveraceae) is a well-known traditional Chinese herb used for treatment of hypertension, inflammation, bleeding and pain for centuries. Although the major bioactive components in this herb are considered as isoquinoline alkaloids (IQAs), little is known about
OBJECTIVE
To investigate the alkaloids in the roots of Dactylicapnos scanden (D. Don) Hutch.
METHODS
The compounds were isolated by various column chromatographic methods. The structures were elucidated by spectroscopic analysis.
RESULTS
Eight compounds were isolated and identified as d-isocorydine
pH-Zone-refining counter-current chromatography was successfully applied for the preparative separation of alkaloids from Dactylicapnos scandens. The two-phase solvent system was composed of petroleum ether-ethyl acetate-methanol-water (3:7:1:9, v/v), where 20 mM of triethylamine (TEA) was added to
Six ingredients were isolated from the whole plant of Dactylicapnos torulosa (Hook. f. et Thomas.) Hutchins. Four of them were identified by UV, IR, 1HNMR and 13CNMR. One of them is a new compound named zijinlongine(I). The three others are 1-methoxyberberium chloride(II), triethylphenylammonium
Dactyllactone A (1), which was isolated from Dactylicapnos scandens, is an isoquinoline alkaloid with a rearranged and reconstructed D ring, making it the first of a new subtype of aporphines. Compound 1 might be derived from a common aporphine skeleton, which may have undergone biogenetic
