OBJECTIVE
To study the chemical constituents of Codonopsis pilosula.
METHODS
The compounds were isolated and purified by column chromatography and their structures were elucidated through spectroscopic techniques (NMR) and physicochemical properties.
RESULTS
The compounds were isolated as
C14-polyacetylenol glycosides from the roots of Codonopsis pilosula.

Prijava / prijava
Eight new C14-polyacetylenol glycosides, containing ene-diyne and ene-yn-ene chromophores named codonopilodiynosides H-M (1-6) and codonopiloenynenosides A and B (7 and 8), respectively, together with three known analogs lobetyolinin, pratialin B, and lobetyolin (9-11), were isolated from an aqueous

Prijava / prijava
Bioactive metabolites in Codonopsis pilosula are of particular interest as an immunostimulant. Methyl jasmonate (MeJA) plays an important role in the elicitation of metabolite biosynthesis. Here, we explored the response of metabolites to MeJA elicitation in C. pilosula adventitious

BACKGROUND
Codonopsis Radix is commonly used as a tonic in traditional Chinese medicine. However, there is no suitable method to assess the quality of Codonopsis Radix based on multiple components having potential bioactivities.
OBJECTIVE
To establish a HPLC/UV method for simultaneous quantitation
Quality evaluation of medicinally-used Codonopsis species and Codonopsis Radix based on the contents of pyrrolidine alkaloids, phenylpropanoid and polyacetylenes.
