Compositions of Essential oils From East-Asian Thymus komarovii, T. nakhodkensis, and T. przewalskii
Essential oils from three east-Asian Thymus species, two of which (T. komarovii Serg. and T. nakhodkensis Gorovoi et Dudkin) grow on limestone (calciphiles) and a third [T. przewalskii (Kom.) Nakai] of which grows on the sandy west bank of Lake Khanka in the vicinity of Novokachalinsk and Turii Rog, Khanka District, Primorsky Krai, were studied.
The calciphilic species T. komarovii was described from the limestone Chandalaz (Lozovyi) Range in Partizan District, Primorsky Krai, and is distributed in southern Primorsky Krai and eastern Siberia [1, 2].
The endemic calciphilic species T. nakhodkensis was recently described as a new species and is found only in the vicinity of Nakhodka. It grows on limestone of the Liaodong geological formation .
The species T. przewalskii grows on the shores of Lake Khanka and differs from the calciphilic Far-East species by a sharp lemon-geranium fragrance. This species is combined with T. chankoanus Klok. and T. mandschuricusRonn. in the floristical...
We thank Dr. M. Jacob (University of Miss., USA) for assistance in studying the antimicrobial activity; Dr. S. Khan, for assistance in studying the antimalarial activity; Dr. B. Tekwani, for assistance in studying the antileishmanial activity (Grant No. AI 27094 NIH, NIAID, Division of AIDS, Grant No. 58-6408-1-603, USDA Agricultural Research Service Specific Cooperative Agreement), and Dr. Zh. B. Iskakova for studying the cytotoxic activity of the essential oils.
