Polygonum lapathifolium

Ahmed, M., Khaleduzzaman, M., and Islam, M.S., Isoflavan-4-ol, dihydrochalcone and chal-cone derivatives from Polygonum lapathifolium, Phytochemistry, 29, 2009, 1990. [Pg.177]

Plant materials were collected in and around Sapporo during the summer months. For the screening test, 10 g (fresh weight) of the aerial parts (mainly leaves/stems) were immersed in 150 ml of MeOH for 3-4 days at room temperature. The resulting extract was then reduced to dryness and the residue was partitioned between EtOAc and water. In order to isolate and characterize the antidotes, Polygonum lapathifolium L. subsp. nodosum, P. sachalinense Fr. Schm. and P. thunbergii were collected in large quantities and extracted with MeOH. [Pg.462]
