Recently, rosemary extracts standardized to diterpenes (e.g. carnosic acid and carnosol) have been approved by the European Union (EU) and given a GRAS (Generally Recognized as Safe) status in the United States by the Food and Drug Administration (FDA). Incorporation of rosemary into our food...

Caulerpa racemosa is a marine Chlorophyta widely distributed in tropical areas, introduced into the Mediterranean Sea since 1990. It has been invading the Mediterranean Sea causing ecological problems. This invasive event can be considered as one of the most serious in the history of species...

Giant salvinia (Salvinia molesta) is one of the most noxious invasive species in the world. Our bioactivity-guided fractionation of ethanol extract of giant salvinia led to the isolation of 50 compounds. Of the six new compounds (1-6), salviniol (1) is a rare abietane diterpene with a new...

The genus Tithonia is an important source of diverse natural products, particularly sesquiterpene lactones, diterpenes, and flavonoids. The collected information in this review attempts to summarize the recent developments in the ethnobotany, biological activities, and secondary metabolite...

Context: The Asteraceae family has been of interest to researchers due to the presence of polyphenolic compounds, mainly flavonoids, which demonstrated antiviral activity. Objective: The hydroethanol extract of the aerial parts of Acanthospermum australe (Loefl.) Kuntze (Asteraceae) and its...

To test a defensive chemistry prediction of the Evolution of Increased Competitive Ability (EICA) hypothesis, Solidago gigantea plants from North American and European (invasive) populations were grown in a screen-enclosed garden. Terpenes from 80 seed grown (dried leaves) and 320 rhizome...

Allelopathy has been suggested as a mechanism promoting the monoculture formation of some invasive exotic plants. Previous studies have shown that hydrophobic extracts of the roots and soil of exotic bitou bush (Chrysanthemoides monilifera spp. rotundata (DC.) T. Norl.) inhibited the seedling...

Rosemary (Rosmarinus officinalis L.) is a slow growing evergreen shrub belonging to the Labiateae family that is considered native to the Mediterranean region. Essential oils extracted from fresh leaves and tender shoots are used in perfumery and medicine. Rosemary essential oil contains up to 91...

The evolution of increased competitive ability (EICA) hypothesis predicts that invasive plant species may escape their specialized natural enemies in their introduced range and subsequently evolve with a decrease in investment in anti-herbivore chemical defenses relative to native conspecifics. We...

Five siphonocladophycean green seaweeds (Caulerpa chemnitzia [C. racemosa var. turbinata], C. faridii, C. manorensis, C. racemosa and C. taxifolia) collected from the coastal waters near Karachi, Pakistan, were analysed for their fatty acid, sterol and diterpene constituents using gas liquid...
