Abstract
|
|
|
|
Secondary phenolic metabolites play an important role in plant defense mechanisms, and increasing evidence indicates that many phenolic compounds are important in human health. To date, few studies have investigated the impact of various medicinal plants on levels of secondary plant metabolites. To address this issue, 82 species of Korean medicinal plants were screened to determine their resveratrol contents. Among 82 medicinal plants, 5 species such as Gardenia jasmonoides, Phlomis umbrosa, Rheum palmatum L., Polygala tenuifolia, Rubus chingii HU contained relatively high concentrations of resveratrol (179.75{sim}42.71;{mu}g/g). But, 40 species including Adenophora triphylla var. japonica HARA were only observed low concentrations or trace of resveratrol, and 20 species including Alpinia officinarum HANCE did not contain a resveratrol.
