Seasonal and circadian rhythms of clerodane diterpenes and glycosylated flavonoids in two varieties of Casearia sylvestris Sw. (Salicaceae)
Casearia sylvestris Sw.(Salicaceae) is noted for its morphological and chemical plasticity and pharmacological properties.The present study investigates two of its varieties: C.sylvestris var.sylvestris, predominant in dense and humid forests and ecotones and characterized by clerodane diterpenes; and C.sylvestris var.lingua, mainly found in xeric
