A new species of Viola L. (Violaceae) from Sichuan, China
Botanical Journal of the Linnean Society, 2005Co-Authors: You-sheng Chen, Qin-er YangAbstract:Viola muliensis Y.S. Chen & Q.E. Yang, a new species of Viola L. (Violaceae) from Sichuan, China, is described and illustrated. Viola muliensis is endemic to Muli County, south-western Sichuan. This new species has yellow flowers with very short spurs and belongs to subsection Brevicalcaratae W. Beck., section Dischidium Ging. It is distinguished from other related species by having pedatipartite leaves. © 2005 The Linnean Society of London, Botanical Journal of the Linnean Society, 2005, 149, 365–368.

A distinctive new species of Viola (Violaceae) from Yunnan, China
Botanical Journal of the Linnean Society, 2005Co-Authors: You-sheng Chen, Qin-er YangAbstract:A new species of Viola (Violaceae) from north-western Yunnan, China, is described and illustrated. Viola dimorphophylla Y. S. Chen & Q. E. Yang sp. nov. is endemic to Zhongdian County, north-western Yunnan, and is very easily distinguishable from all other Chinese species of the genus by having obviously dimorphic leaves, with the basal ones being long petiolate, undivided and widely cordate, and the cauline ones sessile, linear and verticillate. © 2005 The Linnean Society of London, Botanical Journal of the Linnean Society, 2005, 149, 115–119.

Viola nujiangensis (Violaceae), a new species of from northwestern Yunnan, China
Phytotaxa, 2015Co-Authors: You-sheng Chen, Xiao-hua JinAbstract:A new species of Viola (Violaceae) from northwestern Yunnan, China, namely V. nujiangensis is described and illustrated. It is most similar to V. perpusilla , but differs by its rhizome and root stout, spur ca. 4 mm long, stipules and petiole purplish, and leaf blade glabrous on both surfaces.

Cardiovascular effects of Tulbaghia violacea Harv. (Alliaceae) root methanolic extract in Dahl salt-sensitive (DSS) rats.
Journal of Ethnopharmacology, 2013Co-Authors: Kogi Moodley, Irene Mackraj, Yougasphree NaidooAbstract:Abstract Ethnopharmacological relevance In African folk medicine, Tulbaghia violacea Harv.(Alliaceae), a herbaceous plant also known by other common local names such as ‘wild garlic’, ‘society garlic’ and ‘sweet garlic’, has been used for the management, control and/or treatment of several human ailments; including hypertension. The aim of the present study was to investigate the cardiovascular effects of methanolic extract of Tulbaghia violacea Harv. in Dahl salt-sensitive (DSS) rats. Materials and methods DSS rats were treated intraperitoneally (i.p) as follows: distilled water, control (CON) (3 ml/kg/b.w.); captopril (CAP) (25 mg/kg/b.w.); or methanolic extract of Tulbaghia violacea (TVL) (50 mg/kg/b.w.) for 7 weeks. Systolic blood pressure (SBP) was measured bi-weekly whilst 24-hour urine volumes and sodium concentrations were assessed weekly. Animals were sacrificed on day 49 by halothane overdose. Blood was removed for the determination of aldosterone concentration and angiotensin converting enzyme (ACE) activity. Left kidney was harvested for angiotensin Ia (AT1a) receptor gene expression. Results CON showed a significant percentage increase in SBP (mmHg) on day 49 compared to day 0 (baseline values) (9.75±1.7% vs. 2.33±0.77%; p p p p p p p p p Conclusion This study showed that TVL possesses antihypertensive effect in Dahl salt-sensitive rats when administered over a long-term.

isolation and characterization of 16 microsatellite loci in the endemic viola cheiranthifolia humb bonpl Violaceae and their transferability to viola palmensis web berthel
Conservation Genetics Resources, 2015Co-Authors: Priscila Rodriguezrodriguez, Theresa M. Culley, Eduardo Carqué, M A Gonzalezperez, Pedro A. SosaAbstract:Sixteen nuclear microsatellite markers (SSR) were developed for Viola cheiranthifolia Humb. & Bonpl. (Violaceae), endemic to Tenerife Island (Canary Islands), and tested on the closely related Viola palmensis Web & Berthel., endemic to La Palma Island. All loci showed polymorphism and fifteen of them could be transferred to V. palmensis. They had an average of 5 and 3 alleles per locus in V. cheiranthifolia and V. palmensis, respectively. This set of markers will be useful for studying the population genetics of both species, helping to their conservation and management.
