| Erect annual herb, up to 2m tall, probably native to West Africa, cultivated and naturalized throughout tropics; stems robust, purplish; leaves dimorphic; blades on proximal part of stem ovate, those on distal part of stem palmately 3-lobed, lobes lanceolate; flowers solitary, axillary, calyx purplish, cup-shaped, corolla yellow with dark red center, 6-7cm in diameter. \\ | Erect annual herb, up to 2m tall, probably native to West Africa, cultivated and naturalized throughout tropics; stems robust, purplish; leaves dimorphic; blades on proximal part of stem ovate, those on distal part of stem palmately 3-lobed, lobes lanceolate; flowers solitary, axillary, calyx purplish, cup-shaped, corolla yellow with dark red center, 6-7cm in diameter.

| "The major pigment, which was formerly isolated from the calyx and bract of roselle (Hibiscus sabdariffa L.) by Yamamoto et al. (1933), was reported to have the structure of delphinidin pentosido-glucoside. It was newly examined and found that it consists of each 1mol of delphinidin (1mol), glucose and xylose. By a series of analytical procedure its structure must be delphinidin 3-xylosido-glucoside. So it was compared with daphniphyllin (delphinidin 3-xylosido-glucoside), which was isolated from the berries of Daphniphyllum macropodum Miq. and it revealed their identity. Hence, the name “hiviscin”. once given to this substance, must be eliminated from the literature. | "The major pigment, which was formerly isolated from the calyx and bract of roselle (Hibiscus sabdariffa L.) by Yamamoto et al.

| | "The anthocyanins delphinidin-3-O-sambubioside (1) and cyanidin-3-O-sambubioside (2) were isolated by bioassay-guided purification. These compounds showed IC50 values (84.5 and 68.4 μg/mL, respectively), which are similar to those obtained by related flavonoid glycosides. Kinetic determinations suggested that these compounds inhibit the enzyme activity by competing with the substrate for the active site... The competitive ACE inhibitor activity... is in good agreement with the folk medicinal use of Hibiscus sabdariffa calyces as antihypertensive." \\ |

| "Calyxes from the Roselle plant (Hibiscus sabdariffa L.) were used to prepare cold (22 °C for 4 h) and hot (98 °C for 16 min) infusions/teas from both fresh and dried forms. Aroma volatiles were extracted using static headspace SPME and analyzed using GC-MS and GC-O with 2 different columns (DB-5 and DB-Wax). Totals of 28, 25, 17, and 16 volatiles were identified using GC-MS in the dried hot extract (DHE), dried cold extract (DCE), fresh hot extract (FHE), and fresh cold extract (FCE) samples, respectively. In terms of total GC-MS peak areas DHE ≫ DCE > FHE ≫ FCE. Nonanal, decanal, octanal, and 1-octen-3-ol were among the major volatiles in all 4 beverage types. Thirteen volatiles were common to all 4 teas. Furfural and 5-methyl furfural were detected only in dried hibiscus beverages whereas linalool and 2-ethyl-1-hexanol were detected only in beverages from fresh hibiscus. In terms of aroma active volatiles, 17, 16, 13, and 10 aroma active volatiles were detected for DHE, DCE, FHE, and FCE samples, respectively. The most intense aroma volatiles were 1-octen-3-one and nonanal with a group of 4 aldehydes and 3 ketones common to all samples. Dried samples contained dramatically higher levels of lipid oxidation products such as hexanal, nonanal, and decanal. In fresh hibiscus extracts, linalool (floral, citrus) and octanal (lemon, citrus) were among the highest intensity aroma compounds but linalool was not detected in any of the dried hibiscus extracts." \\ | "Calyxes from the Roselle plant (Hibiscus sabdariffa L.) were used to prepare cold (22 °C for 4 h) and hot (98 °C for 16 min) infusions/teas from both fresh and dried forms.

| "The available information on H. sabdariffa shows a wide range of traditional as well as potentially new health applications and therapeutic targets associated with such uses. More robust, randomised, controlled clinical trials would be desirable with well-characterised Hs preparations to corroborate its beneficial effects in pre- and mildly-hypertensive patients. The same applies for its diuretic effects... The effectiveness of Hs extract for metabolic disorders like type II diabetes should be investigated further, as previous clinical studies have shown promising effects on hyperlipidemia and hypertension, conditions strongly correlated with type II diabetes or metabolic syndrome ( Hernandez-Perez and Herrera-Arellano, 2011 and Hopkins et al., 2013)." \\ | "The available information on H. sabdariffa shows a wide range of traditional as well as potentially new health applications and therapeutic targets associated with such uses.

| | Main volatile components of H.sabdariffa (headspace GC-MS) were furfural (31.6-38.6%) and cinnamal (13.8-14.1%). Olfactorly interesting minor components were e.g. benzaldehyde, benzoic acid, eugenol, 5-methylfurfural, and maltol (0.14-0.18%). \\ |
