A new coumarinolignan, cleomiscosin E ( 1 ), together with the known compound cleomiscosin A ( 2 ), has been isolated from the seeds of Brucea javanica (L.) Merr . Their structures were assigned on the basis of spectral studies. These two compounds exhibited potent anti‐inflammatory activities by inhibiting the nitric oxide (NO) production in lipopolysaccharide (LPS)‐activated RAW264.7 macrophages. 相似文献

Phytochemical investigation of barks of Christiana africana led to the identification of cyclopeptide alkaloids, flavonoids, coumarinolignans, iridoids, sesquiterpenoids, and triterpenes. This plant was classified so far in the Tiliaceae family. This study was started while the genomic study of numerous specimens was described in order to establish new criteria for Malvales botanical classification. In the present work, twenty components were identified, belonging to the three major classes of secondary metabolites: alkaloids, phenols, and terpenes. In the first class, cyclopeptides are well‐known compounds in Rhamnaceae and Sterculiaceae. Their presence in Malvaceae (in APG2 sensus) suggests a possible chemical link between the ex‐Tiliaceae and the Malvaceae. 相似文献
