The fragrance of the flower is much more intense and noticeable throughout the warm periode of the day. Usually, the flowers are discovered in yellow, pink and putih colors yet you deserve to find berbeda combination of flowers growing on the same solitary four o"clock plant.


Genetic studies

Around 1900, carl Correns tangan kedua Mirabilis together a design organism because that his research studies on cytoplasmic inheritance. He digunakan the plant"s variegated pipeline to prove that particular factors outside the nucleus influenced phenotype in a way not explained by Mendel"s theories. Correns proposed the leaf colour in Mirabilis was passed top top via a uni-parental mode of inheritance.

Also, as soon as red-flowered plants room crossed through white-flowered plants, pink-flowered offspring, not red, room produced. This is seen as an exception to Mendel"s legislation of Dominance, since in this instance the red and putih genes space of same strength, for this reason neither totally dominates the other. The phenomenon is known as incomplete dominance.



Eight betaxanthins (indicaxanthin, vulgaxanthin-I, miraxanthin-I, -II, -III, -IV, -V and also -VI) have the right to be isolated native M. Jalapa flowers.

Rotenoids (mirabijalone A, B, C and also D, 9-O-methyl-4-hydroxyboeravinone B, boeravinone C and also F, and 1,2,3,4-tetrahydro-1-methylisoquinoline-7,8-diol) have the right to be isolated indigenous the roots.

A fatty acid (8-hydroxyoctadeca-cis-11,14-dienoic acid) is discovered as a minor component in the seed oil.

Analysis the the methanolic extract the the aerial bagian yields ?-sitosterol, stigmasterol, ursolic acid, oleanolic acid and brassicasterol.

Bioassay-guided fractionation the an organic extract the the cell ukuran from a manipulated plant cell culture of M. Jalapa led to the isolation and subsequent identification of an isoflavone, a roteinoid and also a dehydrorotenoid, two of this compounds room responsible for the antimicrobial aktivitas against Candida albicans.

Bioassay-guided fractionation the the methanolic extract the M. Jalapa juga led come the isolation that an aktif polyphenolic amide: N-trans-feruloyl 4?-O-methyldopamine. This compound reflects moderate aktivitas as one efflux pump inhibitor versus multidrug-resistant Staphylococcus aureus.



The flowers are tangan kedua in food colouring. The leaves might be consumed cooked together well, yet only together an emergency food.
