The purpose of this study was to compare the essential oil profiles of four Croatian Teucrium species (Lamiaceae), as determined by GC and GC/MS, with their antiphytoviral efficiency. A phytochemical analysis showed that T. polium, T. flavum, T. montanum and T. chamaedrys are characterized by similar essential oil compositions. The investigated oils are characterized by a high proportion of the...

Snowmelt in alpine ecosystems brings ample water, and together with above-freezing temperatures, initiates plant growth. In this scenario, rapid activation of photosynthesis is essential for a successful life-history strategy. But, strong solar radiation late spring enhances the risk photodamage, particularly before fully functional. We compared photoprotective strategy five forbs: one geophyte...

The aim of this work was to study the chemical composition of Allium obliquum L., A. senescens L. subsp. montanum (Fries) Holub, and A. schoenoprasum L. subsp. schoenoprasum. Sulphur-containing compounds analysis was performed by an LC-MS method, the identification and quantification of polyphenolic compounds through a HPLC-UV-MS method, and the presence of five sterols was simultaneously asses...

The Zingiber genus, which includes the herbs known as gingers, commonly used in cooking, is well known for its medicinal properties, as described in the Indian pharmacopoeia. Different members of this genus, although somewhat similar in morphology, differ widely in their pharmacological and therapeutic properties. The most important species of this genus, with maximal therapeutic properties, is...

In this study, the antimicrobial activity of Myricaria germanica (L.) Desv., Centaurium erythraea Rafn subsp. turcicum (Velen.) Melderis, Prunella vulgaris L., Pelargonium endlicherianum Fenzl., Chrysophthalmum montanum (DC) Boiss. and Jurinea ancyrensis Bornm., were investigated. The antimicrobial activity were evaluated according to the disk diffusion method by using Bacillus megaterium DMS 3...
