โœฆ Synopsis

The incorporation of berberine into jatrorrhizine is demonstrated.

The protoberberine alkaloids, one of the larger classes of isoquinoline alkaloids, exhibit much variability in their methylation/methylenation patterns. Considering only the more common 2,3,9,10 substituted protoberberines, all of the monohydroxy and most of the dihydroxy possibilities are known natural products. Biosynthetically, this presents a problem if a common biosynthetic pathway routed through the dimethoxy compound, scoulerine, is assumed. We wish to report here a possible reconciliation to a common pathway.

## Abstract LIF detection is one of the most sensitive detection methods for CE. However, its application is limited because the analyte is usually required to be derivatized with a fluorescent label. As a result, LIF is seldom used to analyze active ingredients in plants. In this work, we introduc
