Effects of extracts from certain Sideritis species on swimming performance in mice
(John Wiley & Sons LTD, 1996)Extracts obtained from S. libanotica ssp. kurdica, S. lanata, S. perfoliata and S. athoa on mouse swimming performance were investigated using two different doses. In order to compare their effects on the swimming experiments, ... -
New alkaloids from Bongardia chrysogonum
(Taylor & Francis LTD, 1998)Two new alkaloids, 17-desoxy-cis-lamprolobine (1) and bonzakaline (2), along with the known alkaloids lupanine (3) and palmatrubine (4), have been isolated from the ethanolic extracts of Bongardia chrysogonum. Compounds 1 ... -
Alkaloids of Bongardia chrysogonum
(Pergamon-Elsevier Science LTD, 1999)Two new pyridine alkaloids were isolated from the tubers of Bongardia chrysogonum, together with a new lupine alkaloid. The structures of the new alkaloids were characterized by spectroscopic analysis and the stereochemistry ... -
