| Abstract | Hibiscussabdariffa is commonly known under the common names of Roselle, hibiscus, Jamaica sorrel or red sorrel and ‛karkadeh’. Roselle is a summer annual crop that can reach up to 2.4min length.Leaves are alternate situated on cylindrical red stems. Roselle is a perfect multifunctionmodel for food, feed, fiber and medicine (Dutt et al., 2009) andit grows productively in the tropics and sub-tropics (Begum et al., 2015). The young or tender leaves are consumed as a green vegetable andthe main product of this crop is the calyx and epicalyx that is utilized in preparation of beverages (Ottai et al., 2006). Also, Lin et al. (2007) has disclosed benefits of Roselle extract that acts as sexual stimulator, appetizer, cathartic, cancer-protective, anti-cough and refrigerant. H. sabdariffa foremost relevant constituents are organic acids, anthocyanins, polysaccharides and flavonoids (Müller and Franz, 1992). Final fruit production of a single plant can extend to about 1.5 kg, approximately 8 tha-1. Roselle leaves yield may amount to10 tha-1 (EcoCrop, 2007). DaCosta-Rocha et al (2014) reviewedthe importance of Roselle extract and showed it to include antibacterial, anti-oxidant, nephroand hepatoprotective renal/diuretic effect, anti-cholesterol, anti-diabetic and anti-hypertensive effects among others. This might be associated with strong antioxidant activities, repression of α-glucosidase and α-amylase, inhibition of angiotensinconverting enzymes (ACE), and direct vasorelaxant effect or calcium channel modulation. Phenolic acids (esp. protocatechuic acid), organic acid hydroxycitric acid, hibiscus acid and anthocyanins (delphinidin-3-sambubioside and cyanidin-3-sambubioside) are conducive to the reported effects. However, its slow growth at the initial stage leading to increase of weeding cost and land occupation (Wilson andMenzel, 1964) which normally engages the land for 6 – 8 months a year. |
