Abstract:
OBJECTIVETo ascertain the optimal harvest time of Erigeron breviscapus.
METHODThe dry matter weight accumulation of different organs in growth process and contents of scutellarin and coffeic acid ester in whole plant of E. breviscapus were determined.
RESULTThe number of leaves per plant, the dried weight of single leaf and dry matter weight of whole plant and different organs reached the highest after seedling 130-140 d. The content of scutellarin gradually decreased with growth period, and sharply decreased after seedling 140 d. The content of coffeic acid ester varied irregularly with growth period.
CONCLUSIONThe optimal harvest time of E. breviscapus is in early bloom period after seedling 130 d.
