title: [Analysis of total alkaloids in Meconopsis quintuplinervia from different localtites of Qinghai].
abstract: The contents of total alkaloids in Meconopsis quintuplinervia Regel, grown in the different localtites of Qinghai Province, are detected by the method of spectrophometry. The result showed that total alkaloid in different localities were 0. 0262% to approximately 0.0788% , its mean was 0.0502%. The content of total alkaloids in the herb increased with elevation, not with latitude.
