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 کاملCalcium distribution and function during anther development of Torenia fournieri (Linderniaceae)
Potassium antimonite was used to locate calcium in the anthers of Torenia fournieri (Linderniaceae). Abundant calcium precipitates accumulate in the microsporocyte cytoplasm. After meiosis, calcium precipitates are abundant on the microspore wall, as well as the callosic wall of each tetraspore. A large number of calcium precipitates also occur on the outer membranes of the tapetal cells, and i...
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 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 کاملChemical Factors Affecting Anthocyanin Formation and Morphogenesis in Cultured Hypocotyl Segments of Impatiens balsamina.
Introduction The effects of various chemicals on anthocyanin synthesis and morphogenesis in the Impatiens hypocotyl were investigated to determine possible relationships between a specific biochemical process (anthocyanin synthesis) and morphogenetic events (the formation of roots and epidermal hairs). Cultured segments of balsam (Impatiens balsamina L.) provide excellent material for the study...
