Comparison of the Antibacterial Activity and Effect on Membrane Permeability of Hibiscus Acid and a Commercial Chlorhexidine Mouthrinse Against Pathogenic Oral Bacteria and Determination of Hibiscus Acid Toxicity

Journal of Medicinal Food, 2022
The main aim of this study was to determine and compare the antimicrobial effect of hibiscus acid and a commercial 0.12% (w/v) chlorhexidine mouthrinse against Streptococcus mutans, Streptococcus sanguinis, Capnocytophaga gingivalis, and Staphylococcus aureus, and to determine the effect on bacterial cell membrane permeability and the toxicity of ...

Hibiscus acid as an inhibitor of starch digestion in the Caco-2 cell model system. [PDF]

Bioscience, Biotechnology and Biochemistry, 2001
Hibiscus acid, an alpha-amylase inhibitor isolated from roselle tea, and its derivatives were compared in an inhibition test for starch digestion. An alpha-amylase-added Caco-2 system was established as a useful model to evaluate the effects of alpha-glucosidase inhibitors on starch digestion.

ULTRASTRUCTURE AND ACID PHOSPHATASE IN PEDICEL ABSCISSION OF HIBISCUS

American Journal of Botany, 1976
Pedicel abscission in Hibiscus rosa‐sinensis was investigated by light and electron microscopy. During the pre‐abscission period endoplasmic reticulum declined somewhat, dictyosomes increased in number and apparent activity, and mitochondria maintained their numbers.

Determination of anthocyanins, organic acids, and phenolic acids in hibiscus market products using LC/UV/MS

Journal of Food Science
Abstract Hibiscus sabdariffa has gained increasing attention from consumers as a natural, healthy food ingredient, leading to a myriad of available products, yet there is a lack of understanding of the quality and chemical diversity among commercially available hibiscus products.

Inhibitory effect of Hibiscus protocatechuic acid on tumor promotion in mouse skin

Cancer Letters, 1998
Hibiscus protocatechuic acid (PCA), a phenolic acid isolated from Hibiscus sabdariffa L., was evaluated for its ability to inhibit the 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced promotion in skin tumors of female CD-1 mice. Topical application of PCA (5, 10 or 20 micromol) 5 min prior to TPA (15 nmol) treatment twice weekly for 20 weeks to mice

Hibiscus protocatechuic acid inhibits lipopolysaccharide-induced rat hepatic damage

Archives of Toxicology, 2003
Hibiscus protocatechuic acid (PCA), a phenolic compound found in the dried flowers of Hibiscus sabdariffa L. (Malvaceae), was demonstrated to have an antioxidant effect in vitro and in vivo, and an antitumor property in our previous study. In the present study, we used lipopolysaccharide (LPS, an endotoxin) to induce rat liver inducible nitric oxide ...

Hibiscus mutabilis Seed Oil – Characterization of HBr‐Reactive Acids

Lipid / Fett, 1989
AbstractThe seed oil of Hibiscus mutabilis (Chameleon rose) (Malvaceae) contains three HBr‐reactive fatty acids. These are found to be cis‐12, 13‐epoxyoleic (vernolic) acid, 5.9%; 9,10‐methylene‐octadec‐9‐enoic (sterculic) acid. 7.3%; as well as 8,9‐methylene‐heptadec‐8‐enoic (malvalic) acid, 14.0%.

AN OXYGENATED FATTY ACID FROM THE SEED OIL OF HIBISCUS ESCULENTUS

Canadian Journal of Chemistry, 1957
The fatty acids of okra seed oil (Hibiscusesculentus L.) were examined. Acetylation of the oil, followed by saponification and separation of the acids, gave 12,13-dihydroxyoleic acid. From this and other evidence it is concluded that 12,13-epoxyoleic acid is present as a constituent of the glycerides.
