Abstract:
For determining camptothecin and its analogues in several parts of a Chinese tree, Camptotheca acuminata, a small.scale extraction method with a high boiling solvent such as 2.methoxyethanol and a high throughput analysis using a monolithic column were developed. A number of plant samples were simultaneously extracted in a small scale and the contents of the constituents in the extracts were measured within 4 min by this HPLC method.
