RESUMO
AIM To study the chemical constituents from Inonotus sanghuang.METHODS The ethyl acetate extract from Inonotus sanghuang fermentation broth was isolated and purified by silica,Sephadex LH-20 column and HPLC,then the structures of obtained compands were identified by spectral data.RESULTS Twelve compounds were isolated and identified as (2Z,4E)-γ-ionylideneacetic acid (1),p-hydroxyphenethyl (2),5-hydroxymethyl-2-furancarboxaldehyde (3),2-hydroxy-5-hydroxymethyl furan (4),cyclo (D)-proline-(D)-leucine (5),cyclo (D)-proline-(D)-isoleucine (6),cyclo (D)-proline-(D)-valinel (7),cyclo (D)-proline-(D)-phenylalanine (8),cyclo-glycine-(D)-proline (9),cyclo-(D)-serine-(D)-proline (10),cyclo-(L)-alanine-(D)-proline (11),cyclo-(D)-alanine-(D)-proline (12).CONCLUSION All the compounds are isolated from Inonotus sanghuang for the first time.
