Мирабиджалоне Д

What is this

Mirabijalone D is a natural rotenoid isolated from the roots of the night beauty Mirabilis jalapa (Nyctaginaceae family). The compound belongs to the benzopyran-benzopyran structural type: systematic name is 3,6,11-trihydroxy-9-methoxy-10-methyl-[1]benzopyrano[3,4-b][1]benzopyran-12(6H)-one. In the product card it is classified as flavonoids, which corresponds to the origin of rotenoids from the isoflavonoid skeleton.

Natural spring

Mirabijalones A–D are described as four new rotenoids from the roots of Mirabilis jalapa; the structures were established based on a combination of data from HR-EI-MS, IR, UV spectroscopy, ¹H- and ¹³C-NMR with DEPT and two-dimensional techniques HMQC, HMBC, NOESY. Together with them, 9-O-methyl-4-hydroxyboeravinone B, boeravinones C and F, as well as 1,2,3,4-tetrahydro-1-methylisoquinoline-7,8-diol were isolated from the same raw materials. Later, a number of mirabijalons with larger letter indices were obtained from the rhizomes of the white-flowered form of the same species.

Purpose

• reference standard for authentication and quantification of rotenoids in raw materials and extracts of Mirabilis jalapa by HPLC and LC-MS methods
• reagent for phytochemical work: study of the composition of the roots and rhizomes of the night beauty
• comparison sample for structural studies of benzopyrane-benzopyran metabolites

Storage and handling

Microquantities of the natural standard are stored in a tightly closed bottle, in the dark, at a low temperature. Phenolic hydroxyls oxidize in air and light, so keep the opened container closed, and solutions are prepared immediately before analysis. Work with attachments with gloves, without dust.
