- Genus Gerbera was named in
honor of the German naturalist Traugott Gerber and the species named
after Robert Jameson who collected the species. (6)
Gerbera daisy is one of the 15 plants that NASA as beneficial in purifying
indoor air by removing indoor air toxins: TCE (trichlorethylene) and
African daisy is a tufted perennial herb growing to 40
centimeters. Leaves form a rosette, pinnately lobed, pale green above, light
green beneath. Striking inflorescence is borne on a long stalk of up
to 30 centimeters long. Flowers are pink, red, yellow, or white with cream disc
- Widely cultivated in the Philippines.
- Study yielded 6-hydroxy-4-methoxy-5-methyl coumarin from Gerbera jamesonii Bolus.
- Study on 18 cultivars showed the major pigments to be pelargonidin and cyanidin 3-O-malonylglucosides. Co-pigments identified were apigenin and luteolin 7-O- and 4'-O-glucosides, apigenin 7-O-maonylglucoside, kaempferol and quercetin 3-O- and 4'-O-glucosides and malonylated derivatives. (10)
- No reported folkloric medicinal use
in the Philippines.
- In Chinese medicinal medicine used in the preparation of tu-er-feng for curing colds and treating rheumatism. (7)
- Plant extract used in cosmetic and bath preparations
showing skin moisturizing and conditioning effects.
• Indoor Toxins:
Gerbera jamesonii has been designated one of NASA's
indoor toxin removing plants: TCE (trichlorethylene) found in adhesives, dyes, ink, etc. and benzene found in inks, oils, paints, plastics, rubber, etc. (3) NASA's Clean Air Study found Gerbera jamesonii is effective in cleaning the air of formaldehyde, benzene, and trichloroethylene. (10)
• Anticancer / Human Alverolar Basal Epithelial Cell Line: An in vitro study evaluates the anticancer activity of Gerbera jamesonii on A549-Adenocarcinomic human alveolar basal epithelial cell line. Study showed ME of Gj possesses anti-proliferative and anti-metastatic activity on A549 and was nontoxic to lymphocytes. (4)
• Coumarin Biosynthesis: Study reports the biosynthesis of 4-hydroxy-5-methylcoumarin by feeding 14C-labelled compounds to Gerbera jamesonii. The results reveal that this coumarin is formed via a pentaketide, derived from the acetate-malonate pathway, as in the biosynthesis of 5-methylcoumarin in a fungus. (8)
• Acid-Base Indicator of Dye: Study showed the benefits of using Gerbera Jamesonii and Tagetes erecta flower extract as an indicator in all types of acid base titrations because of its economy, simplicity, and wild availability. (9)
• Pigments: Quantitative study of 18 cultivars, with colors ranging from orange through lavender, showed the major pigments to be pelargonidin and cyanidin 3-O-malonylglucosides. Study also identified co-pigments viz., apigenin and luteolin 7-O- and 4'-O-glucosides, apigenin 7-O-maonylglucoside, kaempferol and quercetin 3-O- and 4'-O-glucosides and malonylated derivatives.
