ABSTRACT
The family Gentianaceae are found mostly on the Qinghai-Tibet Plateau in China, which have important medicinal properties. Based on 27 published complete chloroplast genome sequences from Gentiana, Swertia, Halenia, Menyanthes, and Nymphoides of Gentianaceae, the chloroplast genome structure was analyzed. The cp genome sizes of 27 taxa range from 137 to 154 kb, and they contain 101-114 unique genes, including 67-80 protein-coding genes, 30 tRNA genes and four rRNA genes. Also, a Bayesian phylogenetic tree was constructed based on the 27 cp genome sequences with Pentalinon luteum (Apocynaceae) as the outgroup. The tree was topologically consistent with the treatments of traditional taxonomy, and the cp genome sequences have genus- or section-level resolution. In addition, we reviewed the significance of species identification within the family. These cp genome sequences could provide basic data for the endangered species conservation, the genetic analysis and pharmacognostic researches of herbs from Gentianaceae.
ABSTRACT
ABSTRACT: We assessed the damage produced by invertebrate herbivores per leaf lamina and per m2 of populations floating-leaf macrophytes of Neotropical wetlands in the growth and decay periods, and assessed if the damage produced by the herbivores should be taken into account in the estimations of plant biomass of these macrophytes or not. The biomass removed per lamina and per m2 was higher during the growth period than in decay period in Nymphoides indica and Hydrocleys nymphoides, while Nymphaea prolifera had low values of herbivory in growth period. During decay period this plant is only present as vegetative propagules. According to the values of biomass removed per m2 of N. indica, underestimation up to 17.69% should be produced in cases that herbivory do not should be taking account to evaluate these plant parameters on this macrophyte. Therefore, for the study of biomass and productivity in the study area, we suggest the use of corrected lamina biomass after estimating the biomass removed by herbivores on N. indica. The values of damage in N. indica emphasize the importance of this macrophyte as a food resource for invertebrate herbivores in the trophic networks of the Neotropical wetlands.

Nymphoides is an aquatic genus consisting about 50 species, of which few were accepted as traditional medicinal plants in Asia. The literature review revealed that Nymphoides species are widely used in Ayurvedic medicine as a popular drug, i.e. Tagara. They are also utilized by the traditional local healers of different Asian countries to treat various diseases, like convulsion, jaundice, fever, headache, etc. According to the in vivo and in vitro pharmacological studies, Nymphoides species have been claimed to possess major biological activities like anticonvulsant, antioxidant, hepatoprotective, cytotoxic, antitumor, etc. Biochemical profiling of different aquatic plants of this genus revealed the presence of some important phytochemicals as polyphenolic component, flavonoids, triterpenes, carbohydrates, glycosides, etc. Several valuable bioactive compounds including ephedrine, coumarin, secoiridoid glucosides, methyl quercetin, ferulic acid, foliamenthoic acid, etc. were also known to be isolated and identified from different Nymphoides species. The aim of this review is to analyze the published report based on the medicinal values of different Asian Nymphoides species, to provide the updated information about the ethnomedicinal, pharmacological as well as the phytochemical properties for the first time.
