Effects of relay intercropping vegetables on Ophiopogonis Radix based on assay of yield and effective constituents / 中国药学杂志

ABSTRACT

OBJECTIVE: To evaluate the feasibility of relay intercropping Ophiopogonis Radix and vegetables by measuring the yield and contents of effective components and fingerprint analysis. METHODS: The field capacity when relay intercropping Ophiopogonis Radix and vegetables was evaluated, taking Ophiopogonis Radix monoculture as control. The contents of major compound of Ophiopogonis Radix were measured by ultraviolet spectrophotometry and high performance liquid chromatography, and the HPLC fingerprint of Ophiopogonis Radix was established. RESULTS: Relay intercropping vegetables reduced the yield of Ophiopogonis Radix to some extent, but the land equivalent ratios were all more than 1, indicating that it is advantageous to intercrop Ophiopogonis Radix and vegetables. Relay intercropping vegetables did not reduce the contents of chemical constituents in Ophiopogonis Radix significantly. The similarities of all the HPLC fingerprint chromatograms were greater than 0.990. CONCLUSION: Relay intercropping Ophiopogonis Radix and vegetables is a feasible pattern to solve the contention for land between Ophiopogonis Radix and vegetables in the main producing areas of Ophiopogonis Radix, and can be applied and generalized.
