Aim Of The Study: In the Comoros Islands, the aerial parts of Flacourtia indica are used in traditional medicine to treat malaria. Because of the important use of this plant, the phytochemistry of the aerial parts was investigated.
Materials And Methods: Three compounds were isolated from the decoction of this plant material, pyrocatechol, homaloside D and poliothrysoside. The in vitro antiplasmodial activity on the chloroquine-resistant strain (W2) of Plasmodium falciparum and the cytotoxicity on two complementary human cell lines (THP1, HepG2), of AcOEt extract obtained after liquid/liquid extraction of the decoction and pure compounds, were evaluated.
Results: The poliothrysoside isolated from the AcOEt extract presented a strong antiplasmodial activity (IC(50)=7.4 microM) and a good selectivity index (>28) similar to chloroquine.
Conclusion: This study reports for the first time antiplasmodial activity for Flacourtia indica, for its AcOEt extract and the three major constituents and confirms its traditional use.

Various practical strategies have been employed to mitigate the detrimental effects of water deficit stress on plants such as application of nano-stimulants. Nanosilicon plays a crucial role in alleviating the deleterious impacts of both abiotic and biotic stresses in plants by modulating various phyto-morphological and physiological processes. This study aimed to examine the combined effects of drought stress and nanosilicon application on the morphological traits and essential oil content and compositions of hemp (Cannabis sativa L.

The aerial parts (Herba Saniculae) and the underground parts (Radix Saniculae) of (sanicle) have been used traditionally in Austrian folk medicine to treat wounds. Interestingly, in the Austrian vernacular, "Radix Saniculae" can also refer to the underground parts of . This ambiguity can lead to mistakes in using these two plants and, importantly, adulterations.
