Discrimination between wild-grown and cultivated Gastrodia elata by near-infrared spectroscopy and chemometrics

Gastrodia elata is a notable medicinal and edible plant. Wild-grown Gastrodia elata is rare in nature and expensive for its medicinal value, which is often the subject of fraudulent practices by replacing them with inexpensive cultivated ones. Developing a rapid and effective method for identifying wild-grown Gastrodia elata is of great importance. The feasibility of combining near-infrared (NIR) spectroscopy with chemometrics for discriminating...
