Fresh leaves of sorrel (Hibiscus sabdariffa L.) are among the most consumed vegetables in Lubumbashi Democratic Republic Congo (DR Congo). According to literature, this vegetable shows chemical variability depending on culture area. Two varieties species, cultivated and have not yet been studied for their micronutrient content, which fruits main sources. This study investigated mineral total fl...

Scarlet rosemallow (Hibiscus coccineus Walter) is a diploid, perennial, erect, and woody shrub. The species is a desirable inclusion in home landscapes because it is a native plant with attractive flowers and unusual foliage. The objective of these experiments was to determine the number of loci, number of alleles, and gene action controlling flower color (red vs. white) in scarlet rosemallow. ...

A three-way resolution method based on PARAFAC model was applied for the UV-Vis spectra to study the simultaneous degradation of anthocyanins extracted from fresh calyces of flowers of the Hibiscus sabdariffa. This methodology was used to resolve a chemical system, for which there was no a priori information about the composition or the pure spectra, a so-called black system. In the pH range fr...

Locally, Gomutra Silajit is known under the name “RAKTAMANDALAM”. Literally, it means ‘Blood Patch’ or ‘Blood coloured Matter’. In fact, the Ayurvedic texts refer to its colour as that of ‘Japakusuma’ – the China Rose, botanically known as Hibiscus rosasinensis Linn. (Telegu: Mandara). For this reason the local name referring to its colour as ‘Rakta’ (Blood) is apt. The above treatise also indi...

Competition among pollen grains for the chance to fertilize ovules typically involves two stages: arrival times on stigmas and/or the growth of pollen tubes through styles. In a previous study of Hibiscus moscheutos, we found that individual pollen donors often differed in pollen tube competitive ability. Here we determined whether short delays in pollen arrival time altered the average success...

Nootropic acitivity of calyces of Hibiscus sabdariffa Linn. was studied in mice. Elevated plus maze and passive avoidance paradigm were employed to evaluate learning and memory parameters. Scopolamine (0.4 mg/kg, i.p.) was used to induce amnesia in mice. The aqueous extracts of calyces of Hibiscus sabdariffa (HS-100 and 200 mg/kg, p.o.) significantly attenuated amnestic deficits induced by scop...
