A NEW PENTACYCLIC TRITERPENOID WITH ANTIMICROBIAL ACTIVITY FROM THE TUBERS OF Cyperus rotundus Linn
نویسندگان
چکیده
Outcome: Phytochemical investigation of Cyperus rotundus tubers resulted in isolation of four phytoconstituents characterized as n-tritriacontan-16-one (1), Lup-12, 20 (29)-dien-3β-ol-3-α-L-arabinofuranosyl-2'-octadec-9"-eonate (2), npentadecanyl-9-octadecenoate (3) and n-tetradecanyl-n-octadec-9, 12-dienoate (4). Only compound 2 showed antimicrobial activity. Lup-12, 20 (29)-dien-3β-ol3-α-L-arabinofuranosyl-2'-octadec-9"-eonate is a new phytoconstituent isolated for the first time from the plant source. Compound 1, 3 and 4 are reported first time from the Cyperus genus. Phytochemical investigation of tubers of Cyperus rotundus led to isolation of a new triterpenic constituent which may be used as chromatographic markers for quality control of the drugs.

BACKGROUND AND AIMS In recent years, Cyperus rotundus has become a problem weed in lowland rice (Oryza sativa) grown in rotation with vegetables in the Philippines. As the growth of C. rotundus is commonly suppressed by prolonged flooding, the ability of the weed to grow vigorously in flooded as well as upland conditions suggests that adapted ecotypes occur in these rotations. Studies were cond...
