New 2(3->20)Abeotaxane and 3,11-cyclotazane from needles of Taxus cuspidata

Two new taxoid metabolites, 2alpha, 7beta, 10 beta-triacetoxy-5alpha,13alpha-dihydroxy-2(3 ->20)afteotaxa-4(20),11-dien-9one (1) and 2a-acetoxy-5a-cuinamoyloxy-9alpha,10beta-dihydroxy-3,11-cyclotax-4(20)-en-13-one (2), were isolated from the methanol extract of needles of the Japanese yew, Taxus...
