“…Chufa (Eleocharis tuberosa), belongs to the sedge family, is one of the most popular herbal plants in the south-west district of China due to its special medical function (20,21). In traditional Chinese medicine, Chufa (Eleocharis tuberosa) is used to treat cough and phlegmasia, inhibit inflammation, and pharyngitis (22,23).…”

A novel adsorbent, chufa corm peels (CCP), is used for removing Cu(II), Cr(III), and Cr(VI) from aqueous solutions. The adsorption ability and characteristics of the CCP are thoroughly investigated. The adsorption capability for three heavy metal ions is in the order of Cu(II) > Cr(III) > Cr(VI). The morphology and elemental distribution on the biomass of CCP were evaluated by scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS). Fourier-transform infrared spectroscopy (FTIR) analysis revealed that oxygen-containing functional groups, especially carboxylic and hydroxyl groups were responsible for chemical coordination between ionizable functional groups and metal ions. The adsorption features were evaluated based on the batch biosorption experiment. The results showed that the adsorption well meets the Freundlich adsorption isotherm models and pseudo-second-order kinetics model. In summary, this work demonstrated that CCP is an attractive, efficient, and low-cost adsorbent biomaterial that can be used for the removal of heavy metals from environmental contaminations.

“…He was the first to reveal inducible activity of a nitrate reductase in rice seedlings (Tang and Wu, 1957;Tang, 1983). Over more than 30 years (1933 to 1965), Dr. Tang and his associates published a large number of articles in plant biology research, including two in Nature (Chen et al, 1945;Tang and Wu, 1957) and one in Science (Tang and Loo, 1940).…”

“…According to ancient Chinese Compendium of Materia Medica, it has replenishing Qi, nourishing lung and heat clearing effects (Li & Luo, ). Modern studies revealed that this fruit possesses some health benefits such as antimicrobial effects, antioxidant activity, inhibition of inflammation and treatment for pharyngitis and laryngitis (Chen et al ., ; You et al ., ; Zhan et al ., ). Generally, corns of WC are washed, peeled, sliced and packaged, before being commercially sold for use in restaurants, hotels and homes in China, meanwhile, plenty of corns are processed into cans, dry powder and other foods (Chen, ; Zhan et al ., ).…”

There are fourteen compounds tentatively identified from fresh processing waste of different ripened water chestnut (WC) by using high performance liquid chromatography combined with diode array detector and high resolution mass spectrometer (HPLC-DAD-HRMS). The chromatographic profiles show that most of the chemical components of the peels are similar in various ripening stages but the contents increase significantly during ripening. The most abundant metabolite is chlorogenic acid which increased more than four times and reached 3.046 mg g À1 in the peel of fully ripened WC. The second biggest peak is at retention time 1.82 min. The peak in half ripened WC is a combined compound of sucrose and quinic acid which is probably an intermediate product of the cell walls of WC. It is mainly a trisaccharide in near ripened WC, and mainly a tetrasaccharide in fully ripened WC. Peel of fully ripened WC contains all the above compounds, stachyose, coumaroylquinic acid, feruloylquinic acid, feruloylmalic acid, 6,7,3 0 ,4 0 -tetrahydroxyaurone, 3,3 0 ,4 0 ,5,7,8-hexahydroxyflavan, tectorigenin, luteolin, apigenin, rhamnocitrin and dihydrokaempferide. All the above metabolites except the last six flavonoids and chlorogenic acid are the first time reported from WC. Bud of WC contains the same metabolites as the peel. Puchiin contains much less metabolites and the content of chlorogenic acid is only 0.013 mg g À1 . Most of the metabolites are bioactive compounds associated with the health function of WC. Because that peel and bud of the fully ripened WC not only possess 94.44% of the total processing waste but also contain all the bioactive compounds, they have great potential for metabolites utilisation. Results and discussion Components qualitative analysisChromatogram of the extract from peel or bud of fully ripened WC (FRWC) has two very big peaks at Processing waste of water chestnut Z.
