Isolation, characterization and thin-layer chromatography method development of clerosterol palmityl ester: a chemical marker for standardization of leaves of Clerodendrum phlomidis / 中西医结合学报

ABSTRACT

Clerosterol palmityl ester (CPE) is a unique clerosterol derivative isolated and characterized from the leaves of Clerodendrum phlomidis. Considering the uniqueness of this compound, the present study was planned to use CPE as a specific chemical marker and develop a new validated thin-layer chromatography (TLC) method for standardisation of C. phlomidis.
