“…For sweroside, the accumulations in leaf and flower are higher than that of the other parts. In light of the descriptions, the accumulations of these four compounds are variable obviously among different organs, which are in accordance with other medicinal plants [ 38 , 39 ]. The selection of certain part of G. rigescens impacts the medicinal quality.…”

Gentiana rigescens Franch (Gentianaceae) is a famous medicinal plant for treatments of rheumatism, convulsion, and jaundice. Comprehensive investigation of different parts and cultivation years of this plant has not yet been conducted. This study presents the quantitative and qualitative characterization of iridoid glycosides from G. rigescens performed by HPLC and FTIR spectroscopy techniques. The accumulations of loganic acid, swertiamarin, gentiopicroside, and sweroside were determined. Results indicated that their content and distribution in different parts and cultivation years exhibit great variations. Gentiopicroside was identified as the most abundant compound among iridoid glycosides and its highest level was observed in the root of 2-year-old plant. With respect to qualitative variation of metabolic profile, the 1800–800 cm−1 band of FTIR spectra successfully discriminated different parts and cultivation years with the aid of PLS-DA. In addition, combined with PLSR, the feasibility of FTIR spectroscopy for determination of gentiopicroside was investigated by selecting characteristic wavelengths (1800–800 cm−1), which presented a good performance with a residual predictive deviation (RPD) of 3.646. Our results suggested that HPLC and FTIR techniques can complement each other and could be simultaneously applied for comparing and analyzing different parts and cultivation years of G. rigescens.

“…For example, 18 elements (Al, As, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Sr and Zn) were simultaneously detected in G. lutea together with soil samples [ 98 ]. Ca, Na, Zn, Cu, Mn, Fe, Mg, K, P, and B were compared between flowers and roots of G. macrophylla [ 99 ]. AAS and ICP need complex sample pretreatment and standard substances.…”

“…According to the literature, the different species or the same species with different extraction, purification process and analytical methods have different monosaccharides constituents and molecular weight [ 92 , 93 , 94 , 95 ]. Elements were investigated in G. lutea , G. macrophylla , G. rigescens [ 96 , 97 , 98 , 99 ]. The content of elements are based on the herbs own metal uptake and accumulation behaviour, and influenced by the geographical environment (soil PH).…”

“…Different analyses of targets, including trace elements, free amino acids, and polysaccharides, require different preparation methods. Microwave assisted digestion (MAD) employs different acid mixtures and microwave heating systems in the determination of elements [ 98 , 99 , 129 ]. In amino acid analysis, due to no significant fluorophores and presence of interference from impurities in a complex sample mixture, a fluorescence derivatization procedure was introduced into the analysis for providing strong chromophores or fluorophores and facile detection in an HPLC-FLD system [ 100 , 101 , 130 ].…”

The genus Gentiana comprises approximately 400 species. Many species have a wide range of pharmacological activities and have been used therapeutically for thousands of years. To provide comprehensive guidance, utilization and quality control of Gentiana species, this review presents updated information concerning the recent application and progress of chemical analysis including phytochemical analysis, sample preparation and chemometrics. Detailed and comprehensive data including number of analytes, extraction/separation methods, analytical techniques and chemometrics are shown as corresponding tables. These data illustrate that the development of newly discovered compounds and therapeutic uses, understanding of the structure—activity relationship and establishment of harmonious and effective medicinal herb standards are the direction of advancement in future research.

“…Therefore, mixed collection is often used; the natural life of large-leaved gentian seeds is very short, only one year. Importantly, seed germination speed is slow and germination rate is only 20% every year (Niu et al, 2014). Therefore, it is of important application value for guiding the production to study the basic characteristics and germination influence factors of large-leaved gentian seeds.…”

This study investigated the biological characteristics of large-leaved gentian seeds and the effects of germination temperature, illumination, pretreatment, storage temperature and time on the seed germination by calculating the seed germination rate. The results showed that most of gentian seeds were oblong and brown, and its 1000 seed weight was 0.300±0.0004 g. The seed water absorption presented "S"-shaped curve with seed soaking time, including sharp, stable and saturated water absorption stages. The optimum germination temperature of large-leaved gentian seeds was 25°C and the seeds were more conducive to germinate under dark condition than under light condition. Gibberellins soaking could significantly improve the seed germination rate; low temperature storage could prolong the vitality of gentian seeds. In the actual production, the germination rate of gentian seeds can be improved by gibberellins seed dressing firstly and then sowing method, in order to shorten the germination period. This study can provide a good basis for identifying the gentian seeds and large-scale breeding and cultivation.
