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

Developmental changes in the monoterpene composition of Mentha x piperita leaves from individual peltate trichomes

Autor: Bernard Voirin, Christine Bayet

Publikováno v: Phytochemistry. 43:573-580

Different steps of monoterpene metabolism—disappearance of limonene, accumulation of 1,8-cineole, reduction of menthone to menthol and acetylation of menthol—have been studied in different parts of Mentha × piperita leaves of different ages. The
