A new flavonoid glycoside 1 is isolated from the leaves of Bvurssnnpnvirrnr, and its structure is determined on the basis of spectral studies. It is the first flavonoid glycoside to be isolated from the genus BUXUJ. We also report the isolation of methyl syringate from this plant. The isolation and '3C-nmr spectra of buxpsiine and cyclomicrophylline A are also described. Buxus smpewims L. (Bwaceae) is widely distributed in Eurasia. The H20 extracts of the plant find extensive use in the indigenous system of medicine for the treatment of many diseases (1). Previously, we have reported a number of new steroidal alkaloids and two known flavonoids isolated for the first time from the genus Blrxrrr (2-5). In the present paper, we describe the isolation and structure elucidation of a new flavonoid glycoside, galactobuxin {I], along with methyl syringate 121. The isolation and 13Cnmr spectra of two known bases, bwpsiine 131 and cyclomicrophylline A {4], are also described.
