Let K be a number field and let G be a wreath product of cyclic p-groups. We show that if p is odd, then G is K-admissible if and only if G is cyclic or p has at least two divisors in K. If p=2 we obtain a similar partial result. This work relies on a determination of the Galois structure of the gro
## Abstract Three new acylated oleananeβtype triterpene saponins, theasaponins A~6~ (**1**), A~7~ (**2**), and B~5~ (**3**), were isolated from the saponin fraction of the seeds of the Japanese tea plant __Camellia sinensis__ together with the known constituent foliatheasaponin III (**4**). The str
