Background: Fritillaria imperialis is an endangered species with pharmaceutical alkaloids that can be effective in reducing blood pressure and reducing cardiac palpitations. Objective: Comparison of head space solid phase microextraction (HS-SPME) and hydro-distillation (HD) techniques in determination of essential oils in Fritillaria imperialis Methods: Quality and quantity determination o...
cludes about 130 species worldwide which have been found to be rich sources of new and bioactive steroidal alkaloids. Many species of Fritillaria have traditionally been used as herbal remedies in Japanese, Turkish, Pakistani and Southeast Asian folk medicines. In China, the bulbs of many Fritillaria species (“Beimu” in Chinese) have been used as antitussive and expectorant herbs in traditional...
Pingbeimunone A (1), a new compound, together with the known ussuriedine (2), benzo[7,8]fluoreno[2,1-b]quinolizine cevane-3,6,16,20-tetrol (3), ebeiedinone (4), pingbeimine C (5) and verticine (6) were isolated from Fritillaria ussuriensis. The structure was elucidated on the basis of spectral analysis (IR, NMR and MS spectroscopy). In addition, their AChE inhibitory activities were also tested.
Previous studies have reported that chromosome synteny in Lepidoptera has been well conserved, yet the number of haploid chromosomes varies widely from 5 to 223. Here we report the genome (393 Mb) of the Glanville fritillary butterfly (Melitaea cinxia; Nymphalidae), a widely recognized model species in metapopulation biology and eco-evolutionary research, which has the putative ancestral karyot...
The Fritillariaimperialis is grown natively in Iran. Between ornamental bulblet plants, this plant has special place, therefore this plant needs more attention, otherwise this plant will be destroyed in future. For this reason in vitro culture of Fritillariaimperialis was studied. Tissue culture techniques have high potential for mass propagation. The multiplication efficacy of the method by bu...
