lobetyolinin/ツルニンジン属

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

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

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

A comparative study of 56 specimens of three medicinally-used Codonopsis taxa collected from China and 54 commercial samples of Codonopsis Radix available in Chinese, Japanese and Korean markets was carried out by quantitative analysis of seven major components: codonopyrrolidium B (1),
