ferulago angulata (apiaceae), a medicinal plant of western asia, contains essential oils that areused as a food preservative. this study examined and compared the composition of leaf oil with seed oil andof the oils from two different habitats (one from nevakov and the other from shahoo). the oil yield from seedwas 5-fold that from leaves (3.2%/100g compared to 0.63%/100g). cis-ocimene was the ...

in the present study, theoretical chemical reactivates photo isomerization in cis-retinal as a natural photo switch in vision. dft hybrid functional, b3lyp and, post-hf method, were the theoretical methods applied utilizing g09 software. 6-31g+ (d,p) basis set employed for structural optimizations, and single point computations performed using b3lyp/6-31g+(d,p). the isomers cis molecule retinal...
