The intercropping potential of Clerodendranthus spicatus under the rubber plantation with south-north paired row planting system, with cultivated in open field as CK, were studied, and the yield and main medicinal quality indexes of C. spicatus were assayed. The yield and medicinal quality were different with different treatments, different period and different plant parts. The yield of intercropped was much lower than that of CK. The highest yield of the middle and east side in the plantation treatments was 30% only that of CK. Although some extractive contents and ursolic acid contents were slightly higher than or similar to that of CK, the contents of crude flavonoids and rosmarinic acid as well as crude ash in the above-ground of the intercropped were less than that of CK, and the three indexes were worse when the shade density increased in rubber plantation simultaneously. By comprehensive consideration of yield and medicinal quality C. spicatus is not suitable for intercropping under the rubber plantation with south-north paired row planting system.

Key words: rubber plantation with south-north paired row planting system, intercrop, Clerodendranthus spicatus, yield, medicinal quality, shade density
