Bu çalışmanın amacı, Türkiye’de yetişen Campanula lyrata Lam. subsp. lyrata’nın toprak üstü kısımlarından elde edilen metanol ve su ekstrelerinin antioksidan enzim inhibe edici aktivitelerini araştırmaktır. Ekstrelerin in vitro aktiviteleri toplam fenol flavonoit miktar tayini, 2-2´-difenil-1-pikirhidrazil (DPPH), 2,2'-azino-bis (3-etilbenzotiyazolin-6-sulfonik asit) (ABTS), demir şelasyon β-Ka...

OBJECTIVE To determine the chemical profile and steroids composition of the medicinally important plant Aerva lanata (A. lanata) L. METHODS Preliminary phytochemical screening was done by the method as Harborne described. HPTLC studies were carried out as Harborne and Wagner et al described. The Ethyl acetate-ethanol-water (8: 2: 1.2) was employed as mobile phase for glycosides. RESULTS The...

The species Antipathes dichotoma was established by Pallas in 1766 on the basis of a description given by Marsigli (1725) of a specimen collected in the Mediterranean off the coast of Marseille. Marsigli's specimen (Lithophyte no. 9) was described and illustrated as a loosely dichotomously branched colony with strong spines and a biserial arrangement of polyps, with each polyp appearing to have...

Numerous widespread Alpine plant species show molecular differentiation among populations from distinct regions. This has been explained as the result of genetic drift during glacial survival in isolated refugia along the border of the European Alps. Since genetic drift may affect molecular markers and phenotypic traits alike, we asked whether phenotypic differentiation mirrors molecular patter...

in regard to aggregate constitution. The several types of recurrent mutants known to involve change of configuration (such as half-mutants and mass-mutants) correspond with these in frequency of origin and in gametic constitution. The fact that the crossing over which yields them is rare is not surprising since crossing over is regularly found to be reduced in structural heterozygotes in Drosop...
