Abstract Vertebrates have very well defined nervous system. It is established that plant also has an alternative sort of sensitive nervous system. Researchers find a close relationship of the neurotransmission mechanism of animal with the plant and suspects close relation in amino acid transport mechanism among both the organisms. Along with the abilities of determining protein structure and various functions, the chemical properties of amino acids also have great contribution in molecular evolution. Hence, in this present work it is aimed at making comparative study on the distribution of amino acids in the neurotransmission receptors associated to animals and plants, based on the chemical properties the amino acids contain. It is possible to classify 20 amino acids into 8 chemical groups and are identified by specific numeric value. The common pattern finding procedure in numerical representation of protein sequences find some conserved regions in the receptor protein sequences of both the species. The comparative study has been made on distributions of chemical properties in protein sequences of ionotropic glutamate receptor protein sequences and GABA receptor protein sequences of two species namely human, a vertebrate and Arabidopsis thaliana, a plant. Experiments have been carried out to calculate proximity between protein sequences based on the distribution of each chemical group (in percentage) in them and phylogenetic trees have been constructed to find evolutionary relationships of neurotransmission receptors of both the spices.

Abstract Background Genus Fritillaria is one among the biggest genera of family Liliaceae comprising of around 130–165 species. Fritillaria is viewed as a significant genus and a source of significant pharmaceutically active compounds utilized in conventional drugs by folklore. Fritillaria is utilized worldwide as medication and food. Different chemically dynamic components separated from genus Fritillaria, their phytochemistry with structure and pharmacology of these compounds have been extensively reviewed. Main body Fritillaria is utilized for treatment of dyspepsia, chest injury, tuberculosis, cough, asthma, gout, bronchitis, dysuria, sinus, boils, stomatitis, malaria, insanity, anaemia, immunity promoter, remedy for child emaciation, fever, burning sensation, phthisis and broncho-asthma, heart diseases, dysfunction of breathing and nervous system, etc. Different chemical components isolated from genus Fritillaria include around 120 alkaloids, 15 terpenoids as well as saponins, glycosides, volatile components, nucleosides, amino acids, nucleobases, flavonoids, fatty acids and so forth. Conclusions Many Fritillaria species have been utilized in traditional Chinese medication on account of their effects of clearing heat, moistening the lung, alleviating cough, asthma, tumours, scrofula and so on. Fritillaria is utilized for treatment of dyspepsia, chest injury, tuberculosis, cough, asthma, gout, bronchitis, dysuria, sinus, boils, stomatitis, malaria, insanity, anaemia, immunity promoter, remedy for child emaciation, also for fever, burning sensation, phthisis and broncho-asthma, heart diseases, dysfunction of breathing and nervous system, etc.
