Anti-Neurodegenerative Biflavonoid Glycosides from Impatiens balsamina.
Four biflavonoid glycosides, balsamisides A-D (1-4), and nine known compounds (5-13) were obtained from the white petals of Impatiens balsamina. The 2D structures of the purified phytochemicals were established using conventional NMR techniques in addition to the new long-range HSQMBC NMR experiment. Acid hydrolysis followed by experimental and quantum-mechanics-based ECD data analysis permitte...
متن کاملChemical Aspects of the Inheritance of Flower Color in Impatiens Balsamina L.
ECENT applications of chromatographic techniques ( BATE-SMITH 1948,1949) R have facilitated identification of anthocyanin pigments and related compounds in micro quantities, thus permitting extension of the combined genetic and biochemical work initiated by SCOTT-MONCRIEFF (1931) and extended by many others. The genetic studies by the late D. W. DAVIS and his associates (1958) on the inheritanc...
متن کاملTargeted biolistics for improved transformation of Impatiens balsamina.
A transgenesis programme has been developed for Impatiens balsamina that will allow elucidation of the roles played by individual genes in the flower reversion phenomenon shown by this model species. The lack of explants exhibiting adventitious shooting in I. balsamina hinders Agrobacterium-based transformation, but the multiple shoots that arise from cotyledonary nodes present a suitable targe...
متن کاملQuantitative HPLC determination of naphthoquinones in Impatiens balsamina leaves
Impatiens balsamina L. is a plant belonging to the family Balsaminaceae. In Thailand, I. balsamina has traditionally been used for the treatment of thorn or glasspuncture wounds, abscesses, ingrown nails and chronic ulcers caused by allergic reaction of detergents (Fransworth and Bunyapraphatsara, 1992). The groups of compounds commonly found in this plant are naphthoquinones, coumarins, phenol...
متن کاملAdverse Effects of Hydroalcoholic Extracts and the Major Components in the Stems of Impatiens balsamina L. on Caenorhabditis elegans
Impatiens balsamina L. (Balsaminaceae), an annual herb found throughout China, has been extensively used in traditional Chinese medicine (TCM). However, our knowledge regarding the adverse effects of I. balsamina in vivo is very limited. In this present study, the nematode Caenorhabditis elegans model was employed to fully assess the adverse effects of hydroalcoholic (EtOH 55%) extracts of I. b...
