Classification of species found in various foods using an LC-QTOF/MS-based metabolomics approach.

In Korea, is commonly known as Danggui. However, two other species on the market, and , are also commonly called Danggui. Since the three species have different biologically active components, thus, different pharmacological activities, clear discrimination between them is needed to prevent their misuse.

Discrimination of three herbs using LC-QTOF/MS combined with multivariate analysis.

, a popular medicinal herb in Korea, is locally called Danggui; this name is similarly used for and , which are also sold in the retail market. These three herbs have differing therapeutic effects and should be used according to their prescribed purposes. In some retail markets, though, all three herbs are known by the same common name rather than a scientific name and can therefore be confused with each other.

Comparison of Physicochemical Characteristics of Garlic Produced from South Korea and China.

Garlic is widely cultivated and frequently used as a spice in South Korea, due to its characteristic flavor. It is rich in sulfur-containing compounds (for example, allicin) and nonsulfur elements (for example, phosphorus and potassium). During the last few years, the cultivation area of garlic in South Korea has gradually decreased, one of the reasons being the increase in low-priced imported garlic from China.
