We cloned the gene of d-limonene synthase (ArLMS) from Agastache rugosa (Labiatae). The function of ArLMS was elucidated by the preparation of recombinant protein and subsequent enzyme assay. ArLMS consisted of 2077 nucleotides including 1839 bp of coding sequence that encodes a protein of 613 amino acids. This protein has a 60 kDa molecular weight, which is identical to that of d-limonene synt...

The occurrence of diterpenoids in the essential oils of the species of the genus Stachys (Lamiaceae, Labiatae) is reviewed.

The occurrence of diterpenoids from roots and aerial parts of the species of the genus Stachys (Lamiaceae, Labiatae) is reviewed. The presence of these diterpenoids in other taxa and their biological properties have been also reviewed.

The response of soil properties to vegetation types is still not well understood and the relationship between vegetation types and soil properties has not been quantified in highland grasslands. A field experiment was conducted in highland grassland of the Loess Plateau in China to study the distribution of soil properties under different vegetation. 22 plant communities totaling 17 species tha...

the essential oils of zataria multiflora (labiatae) from four regions of iran were investigated by glc and gc-ms methods. the main constituents were carvacrol, thymol, linalool and p-cymene. the percentage of the constituents (in dry and wet plant) of different regions have been compared. antibacterial and antifungal effects of these essential oils have been studied. the essential oil with high...

Composition of the essential oil obtained from dried flowering aerial parts of Teucrium scordium L. (Labiatae) was analyzed by GC and GC/MS. Fifty-six components were identified in the essential oil of T. scordium. The major constituents of the oil were beta-caryophyllene (22.8%), (E)-beta-farnesene (10.4%), caryophyllene oxide (8.6%), 1,8-cineole (6.1%) and beta-eudesmol (5.1%).
