One third of samples of Arctii Fructus, commercially obtained in China, were found to be adulterated with fruits of five other species, Arctium tomentosum, Onopordum acanthium, Aucklandia lappa and Silybum marianum of the family Compositae, possessing achenes, and Amorpha fruticosa of the family Leguminosae possessing a legume. Ar. tomentosum fruit was the most frequent adulterant. These five fruits were distinguished from the fruit of Arctium lappa, the original Arctii Fructus, by the macroscopic morphological characteristics such as the size, color, presence or absence of ridge, spots and pits, remains of the style and pappus scar circle at one end, and by the microscopic characteristics such as outline of outer pericarp, presence or absence and the shape of crystals in the epicarp and endocarp, presence or absence of oil sac in the mesocarp, size and color of the palisade cells in the outer seed coat, presence or absence and the shape of crystals in the inner seed coat and cotyledon.
