TL;DR: From the Indian traditional medicines 78 plants were selected on the basis of their use in the treatment of infectious diseases and only 13% of the plant extracts were active against at least one fungus in a concentration of 50 mg/ml.

TL;DR: Plants traditionally used in India to treat fever or malaria were examined in vitro for antiplasmodial properties against Plasmodium falciparum, and five species seems to be of special interest for further antimalarial studies.

TL;DR: A bioactivity-guided fractionation of an extract of Terminalia bellerica fruit rind led to the isolation of two new lignans, together with 7-hydroxy-3',4'-(methylenedioxy)flavan and anolignan B, which possessed demonstrable anti-HIV-1, antimalarial, and antifungal activity in vitro.

TL;DR: The aqueous extract of the leaves of Olea europaea and Olea lancea both inhibited Angiotensin Converting Enzyme in vitro and a bioassay-directed fractionation resulted in the isolation of a strong ACE-inhibitor namely the secoiridoid 2-(3,4-dihydroxyphenyl)ethyl 4-formyl-3-(2-oxoethyl)-4 E-hexenoate (oleacein).

TL;DR: Traditional medicines reported to be used as anti-hypertensives or diuretics from different regions in the world (China, India and South America) have been investigated and the crude extracts from seven species inhibit the enzyme by more than 50%.
