Bidens pilosa - Picão preto tincture The association between B. pilosa phytochemicals and their bioactivities is not yet fully established and should become a future research focus.
Compelling evidence suggests that the various diverse bioactivities reported for B. pilosa reflect its phytochemical complexity.
B. pilosa is an extraordinary source of phytochemicals, particularly flavonoids and polyacetylenes. Flavonoids are commonly reported to possess anticancer, anti-inflammatory, antioxidant, and other bioactivities. However, the bioactivities of only seven of the 60 flavonoids present in B. pilosa have been studied. The bioactivities of the remaining 53 flavonoids are poorly understood and deserve further investigation. Other classes of compounds found in B. pilosa are also in need of further examination.
B. pilosa extracts and isolated compounds possess anti-cancer activities against a variety of cancer cells.
Extracts suppressed the growth of isolated adult T-cell leukemia cells in vitro.
Researchers from Taiwan reported in 2001 that a simple hot-water extract of Picão preto could inhibit the growth of five strains of human and mouse leukemia at less than 200 mcg per ml in vitro. It may prove to be an effective and useful medicinal plant for treating leukemia.
Polyynes, flavonoids, phenylpropanoids, fatty acids, and phenolics are the primary bioactive compounds of B. pilosa. They have been reported to be effective in the treatment of tumors, inflammation/immune modulation, diabetes, viruses, microbes, protozoans, gastrointestinal diseases, hypertension, and cardiovascular diseases.
