Summary
Purple Basil (Ocimum basilicum var. purpurascens) is an aromatic medicinal and vegetable crop valued for its essential oils and high content of antioxidant polyphenols, particularly anthocyanins [PMID: 38868453, 28025898].
Background
Purple Basil is a variety of Ocimum basilicum L. characterized by purple pigments (anthocyanins) in its vegetative tissue [PMID: 10912675]. It is used as an ornamental plant and in food condiments [PMID: 37513893].
Traditional uses
It is used as an ornamental plant and in food condiments [PMID: 37513893].
Active compounds
Key active compounds include anthocyanins (derived from cyanidin aglycone) [PMID: 33966275], rosmarinic acid [PMID: 32687005], and other phenolic acids such as caffeic, chichoric, and caftaric acids [PMID: 32121015, 37895033, 24996365]. Essential oils contain compounds such as methylcinnamate, linalool, eugenol, and methyl eugenol [PMID: 36313387, 27444992]. Other identified metabolites include apigenin, genistein, and kaempferol [PMID: 10912675].
Mechanism of action
Anthocyanins from purple basil exhibit anti-inflammatory activity by inhibiting lipoxygenase and cyclooxygenase [PMID: 25442525]. The plant's polyphenols demonstrate radical-scavenging and ferric-reducing capacities, contributing to overall antioxidant activity [PMID: 28025898].
Clinical evidence
Evidence DMicrobial infections
Extracts exhibited antimicrobial activity against a broad spectrum of food-borne and human pathogenic micro-organisms [PMID: 28025898].
Evidence DInflammation
Anthocyanins from purple basil leaves showed potential anti-inflammatory activity, specifically inhibiting lipoxygenase and cyclooxygenase [PMID: 25442525].
Safety & adverse effects
Toxicological effects were studied using zebrafish (Danio rerio), though specific adverse outcomes for humans were not detailed in the provided abstracts [PMID: 37513893].
Evidence summary
The current evidence is primarily based on in vitro, in vivo (animal/plant), and phytochemical studies (Level D). There are no human clinical trials provided in the source material.
