BACKGROUND The global resurgence of tuberculosis is a significant threat. Lamiaceae members have been used in folk remedies for centuries. This study was designed to assess the in-vitro antimycobacterial activity of eighteen crude extracts from six plants (Lamiaceae) and to characterize their phenolic and flavonoid compounds. METHODS Six Turkish medicinal plants of the family Lamiaceae (Stach...

The present study aimed to evaluate acetylcholinesterase (AChE) inhibitory and antioxidant activities of Lamiaceae medicinal plants growing wild in Croatia. Using Ellman's colorimetric assay all tested ethanolic extracts and their hydroxycinnamic acid constituents demonstrated in vitro AChE inhibitory properties in a dose dependent manner. The extracts of Mentha x piperita, M. longifolia, Salvi...

The fumigant toxicity of various essential oils and selected monoterpenoid components were tested against the adult German cockroach, Blattella germanica (L.) (Dictyoptera: Blattellidae). Responses varied according to plant material, concentration, and exposure time. High insecticidal activity against adult B. germanica specimens was achieved with allyl isothiocyanate (component of horseradish)...

Antibiotics play an important role in the disease management of aquaculture practices; however antibiotic resistance develops readily in pathogens following antibiotic treatment. Medicinal herbs play an alternative role to tackle this problem. In the present study, 15 selected plant species belonging to Lamiaceae and Apocynaceae were collected from different localities of Tirunelveli district o...

A new species of Orthosiphon (Lamiaceae), Orthosiphoncinereus A.J.Paton, sp. nov. from Angola is described and the eight species of Orthosiphon in Angola listed with reference to previous accounts. Orthosiphonnewtonii Briq. is reduced to the synonymy of Endostemontubulascens (Briq.) M.Ashby.

The structure of the essential oil secretory tissues of Prostanthera ovalifolia R.Br was investigated using bright- and dark-field optical microscopy, and scanning and transmission electron microscopy. The leaves of P. ovalifolia have glandular trichomes of the peltate type common to many Lamiaceae species. The trichomes consist of a basal cell embedded in the epidermis, a stalk cell with heavi...

As a result of human activity, longleaf pine (Pinus palustris Miller) forests in the southern United States have been lost or drastically altered. Many of the plant species that historically occupied those forests now persist only as remnants and are classified as threatened or endangered. In order to safeguard such species, a better understanding of their pollination ecology is needed. We iden...
