We described the ontogenetic changes in phenolic contents and volatile composition of Hypericum androsaemum
L. and Hypericum xylosteifolium (Spach) N. Robson from Turkish flora for the first time. 30 randomly selected
plants were gathered in each of six phenological stages for H. androsaemum (vegetative, floral budding, full
flowering, green capsule, red capsule and black capsule) and each of seven phenological stages for
H. xylosteifolium (vegetative, floral budding, %10 flowering, %50 flowering, full flowering, green capsule and
brown capsule). After dried at room temperature, the plant materials were assayed for phenolic and volatile
ingredients by detailed chemical analyses. The accumulations of several phenolics followed a consistent manner
but, hyperforin, quercetin, rutin, 2,4 dihydroxybenzoic acid, quercitrin, hyperoside, biapigenin, (+)-catechin and
