“…Flavonoids can reduce oxidative stress by directly scavenging free-radicals, due to interfering with free-radical producing mechanisms therefore; increasing the function of endogenous antioxidants [26]. Additionally, flavonoids may regenerate other antioxidants with known immune-enhancing activity, such as vitamin E [27] and carotenoids [28]. The results demonstrated that a treatment with Viola adorata methanolic extracts showed enhancing effect on total and absolute counts of leucocytes (neutrophils and lymphocytes and monocytes).…”

Pants used in traditional medicine contain a vast array of substances that can be used to treat chronic and infectious diseases. One of these medical plant Viola odorata which a popularly known as “Banafshah” and sweet violet in Asia and Europe respectively. It is found in high altitudes of Himalyas, Europe and throughout North America. The study was designed to assess immunological (total and differential count of white blood cells), cytogenetic (micronucleus formation) and hepatoprotective activity of methanolic extract of Viola odorata by using two doses 100 and 200mg/kg. In addition, these effects were assessed after an interaction between the two doses of the plant and methtrexte drug. Results:The results of this study indicated that Viola odorata had the ability to enhance immunity and reduced the frequency of micronucleus formation in bone marrow cells in addition to its hepatoprotective activity. Alternatively, the plant was able to counteract the damage induced by methotrexate 40 mg\kg.

The genus Viola (Violaceae) is among the 40–50 largest genera among angiosperms, yet its taxonomy has not been revised for nearly a century. In the most recent revision, by Wilhelm Becker in 1925, the then known 400 species were distributed among 14 sections and numerous unranked groups. Here we provide an updated, comprehensive classification of the genus, based on data from phylogeny, morphology, chromosome counts, and ploidy, and based on modern principles of monophyly. The revision is presented as an annotated global checklist of accepted species of Viola, an updated multigene phylogenetic network and an ITS phylogeny with denser taxon sampling, a brief summary of the taxonomic changes from Becker’s classification and their justification, a morphological binary key to the accepted subgenera, sections and subsections, and an account of each infrageneric subdivision with justifications for delimitation and rank including a description, a list of apomorphies, molecular phylogenies where possible or relevant, a distribution map, and a list of included species. We subdivide the 658 species accepted by us into 2 subgenera, 31 sections, and 20 subsections. We erect one new subgenus of Viola (subg. Neoandinium, a replacement name for the illegitimate subg. Andinium), six new sections (sect. Abyssinium, sect. Himalayum, sect. Melvio, sect. Nematocaulon, sect. Spathulidium, sect. Xanthidium), and seven new subsections (subsect. Australasiaticae, subsect. Bulbosae, subsect. Clausenianae, subsect. Cleistogamae, subsect. Dispares, subsect. Formosanae, subsect. Pseudorupestres). Evolution within the genus is discussed in light of biogeography, fossil record, morphology, and particular traits. Viola is among very few temperate and widespread genera that originated in South America. The biggest identified knowledge gaps for Viola concern the South American taxa, for which basic knowledge from phylogeny, chromosome counts, and fossil data is virtually absent. Viola has also never been subject to comprehensive anatomical study. Study on seed anatomy and morphology is required to understand the fossil record of the genus.

“…In recent years, five new species have been published in this subsection, i.e. V. changii Zhou and Xing, V. nanlingensis Zhou and Xing, V. jinggangshanensis Ning and Liao, V. guangzhouensis Dong, Zhou and Xing and V. huizhouensis Huang and Fan (Zhou and Xing 2007, Zhou et al 2008, Ning et al 2012, Dong et al 2009, Huang et al 2021). During our continuous field investigations in southern China since 2018, a large number of specimens belonging to V. subsect.…”

Four new Viola species from southern China, i.e. Viola qingruii, V. heyuanensis, V. chaozhouensis, and V. longissima, are described and illustrated based on morphology and molecular phylogeny. Viola qingruii is widely distributed in the coastal mountains of southeastern China, while V. heyuanensis, V. chaozhouensis, and V. longissima, are all narrow endemics in Guangdong Province, China. These species are described and compared with the morphologically related species V. lucens, V. tenuis, V. guangzhouensis and V. huizhouensis. Phylogenetic analysis based on ITS confirmed that all of the four new species belong to Viola sect. Plagiostigma subsect. Diffusae. An identifcation key is provided to distinguish the four new species from other species of V. subsect. Diffusae in southern China. In addition, the origin and evolution of characters such as aerial stems, stolons, elaiosomes and tuberculate seeds in Viola are briefly discussed.
