Abstract:

Orthogonal array design was used to optimize hot ethanol reflux extraction of biochanin A from chickpea (Cicer arietinium L.) seed in this study. Results showed that an optimal compromise between biochanin A yield and purity was achieved by two-time extraction at a material/liquid ratio of 1:10 for 1.5 h each time. This extraction method, thanks to its convenience, safety, low cost and high efficiency, can be popularized for the large-scale production. Moreover, based on optimized hot ethanol reflux extraction, a RP-HPLC method was developed for rapid and accurate determination of biochanin A from chickpea seed.

Key words: chickpea (Cicer arietinium L.) seed, biochanin A, orthogonal array design, RP-HPLC
