Chemical and Antioxidant Analysis of Two Hibiscus Flower Varieties from Brazil, 2013

Analyses of Hibiscus rosa-sinensis and Hibiscus syriacus flowers show a high correlation between their phytochemical compounds and antioxidant activity. The dataset quantifies chemical composition, pectin, and phytochemicals like total polyphenols, anthocyanins, and ascorbic acid from samples collected in Porto Alegre, Brazil, in the first half of 2013. Researcher Analú Barbosa da Silva conducted the study, which suggests these flowers have significant nutritional value as a non-conventional food source.

Use Cases

• Correlating antioxidant activity with specific phytochemical compounds like total polyphenols and anthocyanins.
• Comparing the nutritional profiles of different hibiscus varieties for potential food applications.
• Assessing the chemical composition and pectin content of edible flowers on a wet and dry basis.

Strengths

• Analysis includes three distinct experimental repetitions for phytochemical quantification.
• Specific bromatological methods were used for each nutrient, as mentioned in the description.
• The study quantifies multiple chemical components, including pectin, total polyphenols, anthocyanins, and ascorbic acid.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
