Recovery of Black Cohosh (Actaea racemosa L.) Following Experimental Harvests
—Since European colonization and subsequent commercialization of Appalachian medicinal and edible plants, millions of kilograms of plant material have been extracted from our forests, with little effort to manage these species as natural resources. Roots and rhizomes of black cohosh, a native Appalachian forest herb, are extensively harvested for treatment of menopausal symptoms. As nearly all ...
متن کاملAnalysis of formononetin from black cohosh (Actaea racemosa).
Black cohosh has been widely used as an herbal medicine for the treatment of symptoms related to menopause in America and Europe during the past several decades, but the bioactive constituents are still unknown. Formononetin is an isoflavone with known estrogen-like activity. This compound was first reported to be isolated from black cohosh in 1985, but subsequent research in 2002 using HPLC-PD...
متن کاملEvaluation of Extraction Methods for Isolation and Detection of Formononetin in Black Cohosh (Actaea racemosa L.)
Black cohosh (Actaea racemosa L.) is a medicinal plant from which extracts of the roots and rhizomes (commonly known as rhizomes) have become a popular remedy for the relief of menopausal symptoms. While the chemical constituents responsible for the medicinal properties of the plant are unknown, extracts of the rhizomes are known to contain cycloartane triterpene glycosides, phenolics, and flav...
متن کاملHyperspectral Imaging and Support Vector Machine: A Powerful Combination to Differentiate Black Cohosh (Actaea racemosa) from Other Cohosh Species.
Actaea racemosa (black cohosh) has a history of traditional use in the treatment of general gynecological problems. However, the plant is known to be vulnerable to adulteration with other cohosh species. This study evaluated the use of shortwave infrared hyperspectral imaging (SWIR-HSI) in tandem with chemometric data analysis as a fast alternative method for the discrimination of four cohosh s...
