title: (+)-Bornyl piperate, a new monoterpene ester from Piper aff. pedicellatum roots.
abstract: A new monoterpene ester, (+)-bornyl piperate was isolated from the underground roots of Piper aff. pedicellatum and its structure was elucidated on the basis of spectroscopic evidence and confirmed by X-ray analysis. The compound crystallizes in the triclinic space group P1 with a=7.3232(4) A, b=11.4705(7) A, c=23.2520(14) A, V=1943.6(2) A(3). This compound showed an antituberculosis activity against Mycobacterium tuberculosis (H(37)Ra strain) with the minimum inhibitor concentration (MIC) of 25 microg/ml.
