Zusammenfassung: | As a result of the pressure from population explosion, agricultural land resources require further protecting and rationally utilizing. Intercropping technique has been widely applied for agricultural production to save cultivated area, improve crop quality, and promote agriculture economy. In this study, we employed high-performance liquid chromatography (HPLC) and ultraviolet–visible spectroscopy (UV–vis) combined with chemometrics for determination and qualitative evaluation of several kinds of intercropping system with
Gentiana rigescens
Franch. ex Hemsl. (GR), which is used as an hepatic protector in local communities in China. Results revealed that GR in a
Camellia sinensis
intercropping system contained most gentiopicroside, sweroside, and total active constituents (six chemical indicators), whose content reached 91.09 ± 3.54, 1.03 ± 0.06, and 104.05 ± 6.48 mg g
−1
, respectively. The two applied quantitative and qualitative methods reciprocally verified that GR with 2 years of growth period performed better in terms of quality than 1 year, collectively. |
