title: Further isolation of glycosides from Cynanchum hancockianum.
abstract: Three new glycosides, neohancosides B, C, and D, have been isolated as polyacetates 2, 3, and 4 from Cynanchum hancockianum along with neohancoside A hexaacetate [1]. The new compounds were established as 9-hydroxylinalool-3-O-beta-D-xylopyranosyl-(1-->6)-beta-D-glucopyr anoside heptaacetate [2], 2-hydroxyacetophenone-2-O-beta-D-xylopyranosyl-(1-->6)-beta-D-gluc opyranoside hexaacetate [3], and 6'-O-sinapoylsucrose octaacetate [4] by means of spectroscopic and chemical tools.
