Research Guide
What is Hibiscus Plant Research Studies?
Hibiscus Plant Research Studies is a body of scientific literature examining the phytochemical composition and pharmacological effects of Hibiscus sabdariffa L., particularly its antioxidant properties, anthocyanin content, and therapeutic potential against hypertension, hepatotoxicity, hyperlipidemia, and obesity.
This research cluster contains 14,489 published works on Hibiscus sabdariffa. Studies highlight its bioactive compounds including polyphenols and anthocyanins with demonstrated antioxidant capacity. Research documents potential benefits for conditions such as hypertension and obesity through in vitro, in vivo, and limited clinical evidence.
Topic Hierarchy
Research Sub-Topics
Antioxidant Properties of Hibiscus sabdariffa
Researchers investigate the free radical scavenging activity, total phenolic content, and DPPH assay results of extracts from Hibiscus sabdariffa calyces. Studies compare antioxidant efficacy across extraction solvents and evaluate stability under various conditions.
Anthocyanins in Hibiscus sabdariffa
This area examines the isolation, structural identification via HPLC-MS, and quantification of delphinidin-3-sambubioside and cyanidin-3-sambubioside from Hibiscus sabdariffa. Research explores their color stability, bioavailability, and role in pigmentation.
Hibiscus sabdariffa and Hypertension
Clinical trials and animal models assess the blood pressure-lowering effects of Hibiscus sabdariffa tea, focusing on ACE inhibition and diuretic activity. Meta-analyses synthesize evidence on dosage, duration, and mechanisms involving nitric oxide pathways.
Hepatoprotective Effects of Hibiscus sabdariffa
Studies evaluate protection against carbon tetrachloride-induced liver damage, measuring ALT/AST levels and histopathological changes in rodent models. Research identifies polyphenols responsible for reducing oxidative stress in hepatocytes.
Hibiscus sabdariffa Polyphenols and Obesity
Investigations explore inhibition of pancreatic lipase, adipogenesis suppression in 3T3-L1 cells, and effects on lipid profiles in high-fat diet models. Human intervention studies assess body weight reduction and metabolic improvements.
Why It Matters
Hibiscus sabdariffa research supports applications in herbal medicine and food industry products like beverages and flavorings due to its phytochemical profile. "Hibiscus sabdariffa L. – A phytochemical and pharmacological review" (Da-Costa-Rocha et al., 2014) summarizes evidence from in vitro and in vivo studies plus clinical trials showing effects on hypertension and liver protection, with 880 citations indicating influence. These findings inform development of plant-based therapies for hyperlipidemia and obesity, as traditional uses align with identified antioxidant and hepatoprotective activities.
Reading Guide
Where to Start
"Hibiscus sabdariffa L. – A phytochemical and pharmacological review" by Da-Costa-Rocha et al. (2014), as it provides a complete summary of phytochemicals, traditional uses, and evidence from studies, serving as an entry point to the 14,489 works.
Key Papers Explained
Da-Costa-Rocha et al. (2014) "Hibiscus sabdariffa L. – A phytochemical and pharmacological review" (880 citations) synthesizes phytochemical and pharmacological data, building on earlier antioxidant assays like Elstner and Heupel (1976) "Inhibition of nitrite formation from hydroxylammoniumchloride: A simple assay for superoxide dismutase" indirectly relevant via methodology. It connects to solvent extraction influences in Sultana et al. (2009) "Effect of Extraction Solvent/Technique on the Antioxidant Activity of Selected Medicinal Plant Extracts" (1166 citations) for optimizing Hibiscus bioactivity. Davey et al. (2000) "Plant L-ascorbic acid: chemistry, function, metabolism, bioavailability and effects of processing" (1319 citations) complements by detailing plant antioxidants relevant to Hibiscus polyphenols.

Frequently Asked Questions
What are the main phytochemicals in Hibiscus sabdariffa?
Hibiscus sabdariffa contains anthocyanins, polyphenols, and other bioactive compounds contributing to its antioxidant properties. "Hibiscus sabdariffa L. – A phytochemical and pharmacological review" (Da-Costa-Rocha et al., 2014) details these constituents and their roles in traditional food and medicine uses. Extracts demonstrate activity in scavenging free radicals based on reviewed studies.
What pharmacological effects does Hibiscus sabdariffa show?
Hibiscus sabdariffa exhibits effects against hypertension, hepatotoxicity, hyperlipidemia, and obesity. "Hibiscus sabdariffa L. – A phytochemical and pharmacological review" (Da-Costa-Rocha et al., 2014) compiles in vitro, in vivo, and clinical trial data supporting these outcomes. Antioxidant capacity from anthocyanins underpins much of the therapeutic potential.
How is Hibiscus sabdariffa used traditionally?
Hibiscus sabdariffa is used in herbal drinks, hot and cold beverages, food flavoring, and herbal medicine. "Hibiscus sabdariffa L. – A phytochemical and pharmacological review" (Da-Costa-Rocha et al., 2014) notes its role as roselle in the Malvaceae family for these purposes. Scientific studies validate some traditional claims through phytochemical analysis.
What is the citation impact of key Hibiscus sabdariffa reviews?
The review "Hibiscus sabdariffa L. – A phytochemical and pharmacological review" by Da-Costa-Rocha et al. (2014) has 880 citations. It serves as a central reference in the 14,489 works on this topic. No growth rate data over 5 years is available.
What methods assess antioxidant activity in Hibiscus research?
Antioxidant activity in Hibiscus sabdariffa extracts is evaluated using radical scavenging assays for peroxyl and superoxyl radicals, similar to methods in related plant studies. While not directly on Hibiscus, extraction solvent effects on antioxidants as in Sultana et al. (2009) inform Hibiscus protocols. Da-Costa-Rocha et al. (2014) reference in vitro assays confirming capacity.
