[Effects of Aphid Occurring on Lonicera macranthoides Bud Yield and Quality].

OBJECTIVE

To study the effects of aphid occurring on the quality of Lonicera macranthoides bud.

METHODS

The fresh and dry bud yields of different aphid damage in the same plant were caculated. Contents of chlorogenic acid caffeic acid, luteolin-7-O-gluco-side, isochlbrogenic acid A, macranthoidin B and dipsacoside B in Lonicera macranthoides bud damaged by aphid were determined by HPLC-ELSD.

RESULTS

Aphid significantly affected the contents of luteolin-7-O-glucoside, macranthoidin B, dipsacoside B, and chlorogenic acid (P < 0. 01 or P <0. 05), but had no obvious effect on the content of caffeic acid and isochlorogenic acid A in the bud of Lonicera macranthoides.

CONCLUSIONS

It is supposed to regulate prevention and control of aphids in Lonicera macranthoides GAP base.
