Cepharatines A-D, Hasubanan-Type Alkaloids from Stephania cepharantha.
Summary of "Cepharatines A-D, Hasubanan-Type Alkaloids from Stephania cepharantha."
Four new hasubanan-type alkaloids, cepharatines A-D (1-4), were isolated from the leaves and stems of Stephania cepharantha, and their structures were elucidated by spectroscopic analysis. The structure of 1 was further confirmed by X-ray crystallographic diffraction.

Medical and Biotech [MESH] Definitions
A plant species of the genus STEPHANIA, family MENISPERMACEAE, that contains tetrandrine and bisbenzylisoquinoline alkaloids.
A plant genus of the family MENISPERMACEAE. Members contain cycleanine.
Alkaloids originally isolated from the ergot fungus Claviceps purpurea (Hypocreaceae). They include compounds that are structurally related to ergoline (ERGOLINES) and ergotamine (ERGOTAMINES). Many of the ergot alkaloids act as alpha-adrenergic antagonists.
Tetrahydroisoquinolinol alkaloids in both dextro and levo forms, originally found in SALSOLA plants.
Alkaloids found in OPIUM from PAPAVER that induce analgesic and narcotic effects by action upon OPIOID RECEPTORS.
