Light spectra affect the morphoanatomical and chemical features of clonal Phyllanthus tenellus Roxb. grown in vitro
Phyllanthus tenellus Roxb. is a widely distributed tropical medicinal plant and highly valued for its therapeutic properties. Since variable light conditions can significantly alter phenolic compounds that are the main therapeutic constituents of P. tenellus, including tannins and flavonoids, the development of this plant and its chemical metabolism in response to different light spectra were investigated. To accomplish...

In vitro and in vivo evaluation of quinones from Auxemma oncocalyx Taub. on Leishmania braziliensis
The effect of a quinone fraction (QF) isolated from the heartwood of Auxemma oncocalyx Taub. was investigated in vitro and in vivo on Leishmania braziliensis. Although QF (1-10 μg/mL) showing marked in vitro anti-Leishmania activity (81 to 94%), the oral treatment with the compound did not protect hamsters against progressive L. braziliensis infection. When QF was administered intraperitoneally (20 mg/kg) the lesion...

Evaluation of membrane stabilizing, anthelmintic, antioxidant activity with phytochemical screening of methanolic extract of Neolamarckia cadamba fruits
The current study was directed on methanolic extract of Neolamarckia cadamba fruits, belonging to the family Rubiaceae, to reveal the possible phytochemicals existence and also to evaluate the membrane stabilizing, anthelmintic, antioxidant properties. To estimate the membrane stabilizing activity, both heat and hypotonic solution induced haemolysis techniques were used. The anthelmintic test was conducted on earthworm...
