Background & Aim: Osmotic stress in plants lead to increase free radicals and plants use different mechanisms to scavenge these radicals. So, researchers apply stresses especially drought stress to increase secondary metabolites such as phenolics, and antioxidants. One of the valuable medicinal plants is yarrow (Achillea tenuifolia) which is a perennial plant with different medicinal a...

farct dementia accompanying the increase in aging populations has become a social problem, the development of effective drugs for treating these conditions is vital. Among the traditional Chinese natural medicines, Polygala root (Japanese name: onji)—the root of Polygala tenuifolia WILLDENOW (family Polygalaceae)—may improve memory, since some Chinese prescriptions containing Polygala root have...

We examined the ability of the two hard coral species Agaricia tenuifolia and Porites furcata to store lipids under natural conditions, under experimental starvation (weekly vs. daily feeding) and under heat stress. P. furcata fed more and accumulated greater lipid quantities than A. tenuifolia. Overall, lipid levels in situ showed an inverse relationship to turbidity and eutrophication with hi...

Salinity is a major abiotic factor affecting plant growth and secondary metabolism. However, no information is available about its effects on Schizonepeta tenuifolia Briq., a traditional Chinese herb. Here, we investigated the changes of plant growth, antioxidant capacity, glandular trichome density, and volatile exudates of S. tenuifolia exposed to salt stress (0, 25, 50, 75, 100 mM NaCl). Res...

Mycoses caused by Candida and Cryptococcus species, associated with the advent of antifungal drug resistance have emerged as major health problems. Improved control measures and innovative therapies are needed. This paper describes results from the screening of bio-guided fractionated extracts alone and combinations of Terminalia catappa, Terminalia mantaly and Monodora tenuifolia harvested in ...

The in vitro antiplasmodial activity of Ambrosia tenuifolia organic extract and its isolated sesquiterpene lactones, psilostachyin and peruvin, has been evaluated against Plasmodium falciparum F32 and W2 strains. The cytotoxicity of both compounds was determined on lymphoid cells, and their corresponding selectivity indexes (SIs) were calculated. Peruvin was the most active compound on F32 stra...
