chemical properties of four valuable medicinal plants on oshtorankoh, iran

Iran has different environmental conditions due to specific geographical. therefore, exploring essential oil and flavonoids components among different medicinal may be caused discoveries about valuable components. the present study aimed to study flavonoids profile and essential oils composition of four lamiaceae species i.e. stachys lavandulifolia vahl, teucrium polium l., thymus daenensis čelak., and ziziphora clinopodioides lam. from oshtorankoh located on zagros mountains, iran. the plants were collected during 2014-2015 and were identified using available references. a chemical study using two-dimensional paper chromatography (2-dpc) and thin-layer chromatography (tlc) showed that the four studied species contained flavone c and c-/o glucosides and flavonoid sulfates. the result of the present study revealed that t. polium had high levels of many flavonoids such as apigenin, genistein, isorhamnetin, kaempferol, quercetin, rutin, andvitexin compared to the other studied plants. according to the results of gc/ms analysis, s. lavandulifolia was rich in α‑pinene (21.16%) and 1,8‑cineol (16.95%), t. polium in α‑pinene (12.21%) and sabinene (9.55%), t. daenensis in γ‑terpinene (36.98%) and p‑cymene (26.87%), and z.‍clinopodioides in piperitone (16.84%) and 1,8‑cineol (16.11%) components.
