Lonicera fulvotomentosa Hsu et S. C. Cheng is widely distributed in southwest China. Dried flowers of this plant are used in the treatment of fever, pain, and infectious diseases, such as SARS and avian influenza. The present study aimed to evaluate the chemical composition and bioactive ingredients of dried flowers from Lonicera fulvotomentosa Hsu et S. C. Cheng plants grown in yellow loam and karst soil in Guizhou, China. All samples from the two different sources exhibited different ranges of changes in the content of moisture, lipids, fiber, ash, crude protein, and carbohydrates, varying from 3.25 to 3.63%, 7.76 to 9.93%, 6.93 to 7.34%, 12.32 to 12.76%, 7.85 to 8.53%, and 56.21 to 59.77%, respectively. The ICP-AAS analysis indicated that the predominant mineral elements in the dried flower were Ca, K, Fe, and Mg. The content of these elements was: 297.34-351.26 mg kg-1, 132.56-140.37 mg kg-1, 37.77-41.25 mg kg-1, 9.47–11.36 mg kg-1 for Ca, K, Fe and Mg, respectively. The three phenolic acids (gallic, caffeic acid, and chlorogenic acid) and five flavonoids (rutin, luteolin, quercetin, apigenin, and kaempferol) were found with the HPLC method. We concluded that the chemical composition of Lonicera fulvotomentosa Hsu et S. C. Cheng is similar to Lonicera japonica, but the nutritional composition and mineral element content are different, and the content of chlorogenic acids and caffeic acid from the dried flowers obtained from different soils were extremely high. Lonicera fulvotomentosa Hsu et S. C. Cheng, grown in different soils, can be used as a substitute for L. japonica in traditional Chinese medicine. Due to the specific soil parameters which can influence the content of bioactive ingredients, plants from different sources may cause different medicinal effects.
