Biological Activities

Viola tricolor has demonstrated a diverse range of therapeutic potential through various biological activities. Research indicates that the plant possesses significant anticonvulsant properties, effectively reducing seizure latency and incidence in animal models. Additionally, its extracts exhibit notable antioxidant and antiprotozoal activities, showing promise in inhibiting the growth of several Babesia and Theileria parasites. The species also contains specialized cyclotides that exhibit potent cytotoxic effects against specific human cancer cell lines. Together, these findings highlight the plant's importance as a rich source of bioactive compounds for future drug development.

Compounds

Viola tricolor is a medicinal plant characterized by a diverse array of bioactive chemical constituents. Phytochemical screenings have confirmed that the plant contains significant amounts of flavonoids and phenols. Research into its biosynthetic pathways has also highlighted the presence of specific flavonoid C-rhamnosides, such as violanthin. Furthermore, the species is a source of potent cytotoxic cyclotides, including the protein known as varv E. Among these small lipophilic proteins, vitri A has also been identified as a highly significant compound within the plant.

Conditions

Viola tricolor demonstrates significant antiprotozoal activity by suppressing the growth of various Babesia parasites. Specifically, the methanolic extract of this plant effectively inhibits B. bigemina and B. caballi in vitro. It also shows a clear ability to treat B. divergens and Babesia bovis by reducing their growth at specific concentration levels. Furthermore, oral administration of the extract has been shown to prohibit the multiplication of B. microti in vivo. These findings highlight the potential of Viola tricolor as a source for developing new anti-protozoal drug molecules.

Preparations

Viola tricolor is prepared as a hydroalcoholic extract to investigate its cytotoxic, apoptogenic, and anticonvulsant properties. This plant is also prepared as an aqueous Viola extract to study its influence on lymphocyte functions and its immunosuppressive activity. Researchers have utilized an aqueous Viola herbal extract to explore how bioactive cyclotides inhibit the proliferation of activated lymphocytes. Furthermore, Viola tricolor is prepared as a crude fraction rich in small lipophilic proteins to facilitate the isolation of cytotoxic cyclotides. Finally, the plant is prepared as an ethyl acetate fraction, which has demonstrated potent anticancer activity and significant anticonvulsant effects.
