Another source of food anthocyanins that is widely studied is roselle extracts. The roselle, known as Hibiscus sabdariffa flower in the Africa had gained enormous attention for the past 20 years, mainly due to the attractive colours it offers. The major anthocyanins in roselle flower extracts is delphinidins (318 mg/L) and its derivatives followed by cyanidins (112 mg/L) (Rasheed et al. 2018). Anthocyanins from roselle that were encapsulated could have a half-life from 7 days when stored at room temperature and up to 180 days when stored at 5°C (de Moura et al. 2018). Moreover, a study comparing the freeze-dried roselle powder in a beverage system with beverages containing colourants such as SAN RED RC® and synthetic carmoesin was carried out by Duangmal and Sueeprasan 2004. The results obtained showed that roselle drink was more stabilised with the addition of maltodextrin and that the colour changes during storage were more correlated to the increase in lightness and decrease in chroma, with overall acceptance of 56 days.

Hibiscus sabdariffa tea is in extensive use across the globe both as a beverage and as a treating agent for hyperlipidemia. [42] Hibiscus sabdariffa L. (Malvaceae; common name “roselle”) is a plant cultivated in Sudan and Eastern Taiwan. [43] The flower of the plant is “generally recognized as safe” (GRAS) as a food by the US Food and Drug Administration (FDA). It is highly beneficial in the sense that it contains potent antioxidant, antihyperlipidemic, antiatherosclerotic as well as hepatoprotective properties. H. sabdariffa are rich in anthocyanins, which are known to be effective in controlling weight gain and treating obesity. [43, 44] In a study conducted on high-fat diet-induced Mesocricetus auratus hamster, it was found that the floral extracts of H. sabdariffa could be effective in controlling body weight and adipose deposition.

Source of a red beverage known as jamaica in Mexico (said to contain citric acid and salts, serving as a diuretic). Calyx called “karkade” in Switzerland, a name not too different from the Arabic. Karkade is used in jams, jellies, sauces, and wines. In the tropics the fleshy calyces are used fresh for making roselle wine, jelly, syrup, gelatin, refreshing beverages, pudding, and cakes; dried roselle is used for tea, jelly, marmalade, ices, ice cream, sherbets, butter, pies, sauces, tarts, and other desserts. Calyces are used in the West Indies to color and flavor rum. Tender leaves and stalks are eaten as salad and as a potherb and are used for seasoning curries. Seeds have been used as an aphrodisiac coffee substitute. Fruits are edible.3 Perry16 cites one study showing roselle’s usefulness in arteriosclerosis and as an intestinal antiseptic. Roselle is cultivated primarily for the bast fiber obtained from the stems. The fiber strands, up to 1.5 m long, are used for cordage and as a substitute for jute in the manufacture of burlap.3,61
Systematic review on activity of liposomal encapsulated antioxidant, antibiotics, and antiviral agents

Hibiscus sabdariffa Linn, or Roselle, is a medicinal plant used extensively in traditional medicine. The extracts of Roselle calyces possess antioxidant activity and have potential for development as active ingredients in cosmetic products. The limitations of using Roselle extracts in cosmetics are due to its low skin permeation and dermal irritation. Liposome technology is an obvious approach that might overcome these problems. Liposome formulations of standardized Roselle extracts were developed with various lipid components (Pinsuwa et al.2010, Rojanarat et al.2011).

Roselle (Hibiscus sabdariffa L.) is an edible plant, which is rich in vitamins, minerals and bioactive compounds such as organic acids, phytosterols and polyphenols [1–3]. In addition, calyces of Roselle rich in polyphenolic acids, flavonoids, anthocyanins and protocatechuic acid have been reported to possess strong antioxidant and antitumor properties [2–4]. Many investigations highlight the additional role of polyphenolic acid, flavonoids and anthocyanins that may act as antioxidants or via other mechanisms contributing to the hepatoprotective actions. The extract of Roselle inhibits low-density lipoprotein (LDL) oxidation in vitro and decreases serum lipids in cholesterol and high fructose-fed rats. Therefore, dietary extracts of Roselle may reduce the incidence of liver stress through their antioxidant activity [4,5]. Red beet (Beta vulgaris L.) is a taproot plant grown for food sources [6,7]. The concentrated red coloration of beetroots is from betalains, which is a group of phenolic compounds of plant origin. The antioxidant mechanism present in beetroots has been reported to be due to the inhibition of lipid peroxidation [6,7], increased resistance to the oxidation of low-density lipoproteins [6] and chemo-preventive effects [8]. In addition to betalains produced by red beets, other bioactive compounds present in minute quantities are flavonoids and hydroxycinnamic acids such as gallic, caffeic and syringic acids [6–9]. Several types of research have described betalains potentials as very high in antioxidants and anti-inflammatory activities in an in vitro system and in vivo in animal models [6,10]. The functional food concept was developed from the consumption of a diet rich in fruits and vegetables with added health benefits leading to a wholesome lifestyle. Studies have reported the significance of plants in the management of human health.

Hibiscus sabdariffa, known as roselle, is used in traditional medicine for the management of high blood pressure, fever, and other diseases. Different parts of this plant are used for medical purposes and as refreshing drinks, food products or lotions. The hypotensive effects of H. sabdariffa have been widely reported in animals and human studies (Da-Costa-Rocha et al., 2014; Hopkins et al., 2013; Ngamjarus et al., 2010; Riaz & Chopra, 2018; Wahabi et al., 2010).
