Gen info
- Hibiscus is a genus of flowering plants in the mallow family, Malvaceae. The genus is large, comprising several hundred species that are native to warm temperate, subtropical and tropical regions worldwide. Species are renowned for their large, showy flowers, commonly known simply as hibiscus or, less widely known, as rose mallow. (34)
- Etymology:
The species name lives up to the epithet, mutabilis meaning changeable or variable. Many of the common names draw upon its colorful mutability - opening up pale pink or white and darkening into shades of red as the day advances. Confederate Rose
is a common name that colors the epithet with the drama of the Civil War, a felled soldier bleeding unto a bed of white hibiscus flowers, the petals slowly soaking red.
- Flower colors: The flower color change in H. mutabilis is most spectacular. Flowers are white in the morning, pink in the afternoon, and red in the evening. Temperature may be an important factor affecting the rate of color change as refrigerated white flowers remain white until taken out, slowly turning to pink as they warm. (31)

Botany
Amapola is an erect, branched bushy shrub or small tree, about 2 to 4 meters high, densely covered with short, grayish, stellate hairs. Leaves are broadly ovate to orbicular ovate, 5-lobed or 5-angled, 7 to 20 centimeters long, with pointed tip, heart-shaped base and toothed margins. Calyx is 3 to 4 centimeters long, with 5 oblong-ovate lobes, connate below. Corolla is 10 to 12 centimeters in diameter, single or double, opening pale pink or nearly white, growing darker in color as the day advances.

Distribution
- Occasionally planted for ornamental purposes in the larger towns of the Archipelago.
- Not spontaneous.
- Native of the Old World.
- Now pantropic.

Studies
Antiproliferative / Anti-HIV1 Reverse Transcriptase / Lectin:
Study isolated a hexameric 150-kDa lectin from dried H mutabilis seeds. The galactonic acid-binding lectin potently inhibited HIV-1 reverse transcriptase. It also exhibited weak antiproliferative activity towards hepatoma HepG2 cells and breast cancer MCF-7 cells. (1)
Nitric Oxide Scavenging Activity: Study of the ethanol extracts of four medicinal plants, including Hibiscus mutabilis, showed dose-dependent NO scavenging activity. Results suggest a potential for the plants as novel therapeutic agents in the regulation of pathologic conditions caused by excessive generation of NO and its oxidation product. (2)
Anti-Tyrosinase Activity: In a study of four species of Hibiscus, H mutabilis was second to H tiliaceus in anti-tyrosinase and antioxidant activities. Total phenolic content (TPC) of leaves was 861 ± 92 mg GAE/100 g and an ascorbic acid equivalent antioxidant capacity (AEAC) of 877 ± 137 mgAA/100g. (6)
Bacteriostasis: In a study of extracts of H. mutabilis, the bacteriostasis effect was highest with E. coli and best with a 70% alcohol extract. (8)
Ferulic Acid / Leaves / Anti-Diabetic: Ferulic acid (FRL) purified from the leaves of Hibiscus mutabilis, showed impressive effects in preventing saturated fatty acid (SFA)induced defects through reduction of insulin receptor ß in skeletal muscle cells. Impairment of insulin signaling molecules by SFA was waived by the FRL. In high fat diet fed diabetic rats, FRL reduced blood glucose level and enhanced lipid uptake activity of adipocytes isolated from adipose tissue. Collective, FRL exhibited features for prevention of lipid induced insulin resistance, with a therapeutic potential use for T2DM. (9)
Antimicrobial / Anti-Inflammatory: Antimicrobial testing on various organisms showed satisfactory results. A methanolic extract showed good activity against Bacillus subtilis. An ethyl acetate extract showed comparable anti-inflammatory activity when compared to standard drug Nimuselide. (10)
Antidiabetic / Leaves: Study evaluated a methanolic extract of leaves for anti-diabetic activity in alloxan induced diabetic wistar rats. Results showed significant protection and maximum reduction in glucose in comparison to standard glibenclamide. (11)
Hepatoprotective / Leaves: Defatted phenolic fraction of leaf, stem, and flowers of Hibiscus mutabilis was evaluated against carbon tetrachloride induced hepatic injuries in rats. Results showed curative potential of the defatted antioxidant ethanolic fractions with treatment significantly modulated the enzymes to normal values accompanied by histopathological evidence. (12)
Anti-Allergic Effects / Petals: In vivo assay of aqueous extract of petals on mice isolated various flavanoids. Flavonol triglycoside, quercetin 3-o-1-beta-D-xylopyranosyl and beta-D-galactopyranoside showed significant anti-allergic effects. (15) (16)
• Analgesic / Bark: Study evaluated a bark extract of Hibiscus mutabilis in Wistar albino mice for analgesic activity using hot plate method and peripheral activity by acetic-acid induced writhing test. All the extracts showed significant analgesic activity. A methanol bark extract showed more inhibitory effect. The peripheral analgesic activity may be attributed to PG synthesis inhibition. (18)
• Anti-Diabetic / α-Glucosidase Inhibitory Activity / Leaves: Study evaluated the anti-diabetic (α-glucosidase inhibitory) effect of H. mutabilis leaf extract. Ferulic acid and caffeic acid were identified as α-glucosidase inhibitors present in H. mutabilis. Results suggest further study of the plant for its potential use in the management of diabetes. (19)
• Rutin and Isoquercetin / Seasonal and Age Variation: Rutin and isoquercitrin are flavonoid glycosides with significant biologic activities i.e., anti-inflammatory, hepatoprotective, antibacterial, anitoxidant, and antitumor. Study reports on a precise and simple method for the determination of rutin and isoquercitrin contents in HM folium. Rutin and isoquercitrin in MNF (mature green leaf) harvested in different periods showed significant differences and were highest in mid-December, and both were higher in mature green leaf than in nearly withered leaf. (20)
• Anti-Filarial / Ferulic Acid / Leaves: Study evaluated the in vitro activity of methanolic extract of leaves of Hibiscus mutabilis against bovine Setaria cervi worms. Bioassay-guided fractionation isolated ferulic acid from the ethyl acetate fraction. The crude extract and ferulic acid showed significant micro- and macrofilaricidal activities against microfilaria and adult of S. cervi by both worm motility and MTT reduction assay. In ferulic acid treated adult worms there was extreme cellular disturbances characterized by chromatin condensation, in situ DNA fragmentation and nucleosomal DNA laddering, suggesting anti-filarial effect through induction of apoptosis and by down regulating and altering the level of some key antioxidants (GSH, GST, and SOD) of the filarial nematode S. cervi. (21)
• Mechanochemical Assisted Extraction of Rutin: Study reports on the mechanochemical-assisted extraction (MCAE) technique for the efficient extraction of rutin from H. mutabilis. Compared with heat reflux and superfine grinding extraction, MCAE showed advantages in efficiency, no organic solvent consumption and much lower extraction temperature. (22)
• Mutagenicity Study / Acute Toxicity Study / Leaves: Study evaluated the potential mutagenicity of effective fraction of leaves in mice. Acute toxicity assessment by mortality of mice in LD50 in Ames test used highest dosage of 5000 ≤g/dish. No mutagenicity was noted. The amount of effective fraction of leaves given to mice was 3124 g/kg, which is 150-fold the effective dosage. Results suggest the effective fraction of leaves is a safe Chinese herbal preparation. (23)
• Hepatoprotective / CCl4-Induced Injury: Study evaluated the preventive and therapeutic effects of H. mutabilis on acute hepatic injury induced by carbon tetrachloride in rats. Results showed hepatoprotective effect with significant reduction in ALT and AST and pathological changes. (25)
• Dyeing / Flowers: Aqueous extract of gulzuba flowers yielded dye shades with good fastness properties, with good scope in the commercial dyeing of cotton, silk for garment industry, and wool yarn for the carpet industry. (26)
• Effect on Renal Ischemia Reperfusion Injury / IL-1 Inhibition: Study evaluated the effect of fraction of Hibiscus mutabilis on renal ischemia reperfusion injury in rat. Results showed decrease in BUN and creatinine, Renal pathological injury was significantly mitigated. The effect may underline its inhibitory action on interleukin-1 release. (27)
• Simultaneous HPLC Analysis of Content / Antioxidant Activity: HPLC analysis simultaneously determined the contents of rutin, protocatechuic acid, catechin, quercetin, and luteolin in Hibiscus mutabilis. Quercetin was used as internal standard. Results showed that the linear relationship, stability, precision, repeatability, and recovery rate of the method were great with little difference between determination result and traditional external standard method. Antioxidant capacity of H. mutabilis was evaluated by DPPH and ABTS in vitro, which is of reference significance for the pharmacodynamic study and product application of H. mutabilis. (28)
• Simultaneous HPLC Analysis of Content / Antioxidant Activity: Hibiscus exhibits high variation in chromosome number both within and among species. Study provides an exact chromosome number and a physical map, which will be useful for genome assembly and contribute to molecular cytogenetics in the genus Hibiscus. (
30)
• CNS Depressant / Bark: Study reports on the CNS depressant activity of petroleum ether, ethyl acetate and methanol extracts of H. mutabilis bark using pentobarbitone-induced sleeping time and locomotor activity testing. Results showed the petroleum ether extract showed best CNS depressant activity. (
32)
• Anti-HSV-II Activity: Experimental assessments were made on the anti-HSV-II activity of 500 herbs by determinations of the virus inhibition logarithm (VIL) Thirteen highly effective herbs (VIL greater than or equal to 4.00) were screened cut, providing a rational basis for clinical therapy. Among the most effective herbs, 10 were aqueous extracts, which included Hibiscus mutabilis and three were alcohol extracts. (
