Background: Enhydra fluctuans Lour, a tropical herb, commonly known as helencha or harkuch, belonging to family Asteraceae, and is an edible semi-aquatic herbaceous vegetable plant with serrate leaves, grows commonly in different parts of the world. Enhydra fluctuans possesses potential pharmacological role against inflammation, cancer, diarrhea, microbial infection, diabetes, and so on. Aim of the review: This review aims to provide the most current information on the botanical characterization, distribution, traditional uses, chemical constituents, as well as the pharmacological activities of Enhydra fluctuans Lour. Materials and methods: The recently updated information on Enhydra fluctuans was gathered from scientific journals, books, and worldwide accepted scientific databases via a library and electronic search (PubMed, Elsevier, Google Scholar, Springer, Scopus, Web of Science, Wiley online library. All of the full-text articles and abstracts related to Enhydra were screened. The most important and relevant articles were carefully chosen for study in this review. Results: Crude extracts and isolated compounds of Enhydra fluctuans Lour has been reported pharmacologically active against cytoprotective, analgesic and anti-inflammatory, antimicrobial, anticancer, anti-diarrhoeal, antihelmintic, CNS depressant, hepatoprotective, thrombolytic, antidiabetic, anti-oxidant, phagocytic and cytotoxic, and neuroprotective potential activities. Discussion: Phytochemical analysis from different studies has reported Germacranolide, Sesquiterpene lactone, Flavonoid, Essential oil, Steroid, Diterpenoid, Melampolide, Sesquiterpene lactone, Isoflavone glycoside as major compounds of Enhydra fluctuans Lour. Conclusions: However, more research is important to explore the mode of action of bioactive components of the plant and its therapeutic capabilities.

AbstractKudzu is an invasive perennial climbing vine characterized by fast growth rates and tolerance to control measures. Repeated applications with high rates of 2,4-D plus picloram provide effective kudzu control, but picloram use is not permitted in certain states due to groundwater pollution concerns. Studies were conducted in Alabama and Florida to compare kudzu control with aminocyclopyrachlor, a new herbicide, to control provided by aminopyralid, clopyralid, metsulfuron methyl, and picloram plus 2,4-D, which are common treatments for kudzu management. Two annual applications of the same herbicide treatment were evaluated for effects on kudzu cover, kudzu volume index, and cover of other vegetation. Aminocyclopyrachlor at 140 to 280 g ae ha−1 (2 to 4 oz ae ac−1) was as effective as the standard 4.48 kg ae ha−1 (4 lb ae ac−1) 2,4-D amine plus 1.2 kg ae ha−1 picloram for kudzu control. There were no differences in kudzu control among the three rates of aminocyclopyrachlor tested. Colonization by graminoids, forbs, and Rubus spp. at 2 yr was greatest for herbicides providing the best kudzu control: aminocyclopyrachlor, and 2,4-D plus picloram. Herbicide treatments were more effective in controlling kudzu at the Alabama location, but repeated annual applications for 2 yr did not completely eliminate kudzu with any treatment at either site.

A novelβ-glucosidase gene (Bgl3B) of glycoside hydrolase (GH) family 3 was cloned from the thermophilic fungusTalaromyce leycettanusJM12802 and successfully expressed inPichia pastoris. The deduced Bgl3B contains 860 amino acid residues with a calculated molecular mass of 91.2 kDa. The purified recombinant Bgl3B exhibited maximum activities at pH 4.5 and 65°C and remained stable at temperatures up to 60°C and pH 3.0−9.0, respectively. The enzyme exhibited broad substrate specificities, showingβ-glucosidase, glucanase, cellobiase, xylanase, and isoflavone glycoside hydrolase activities, and its activities were stimulated by short-chain alcohols. The catalytic efficiencies of Bgl3B were 693 and 104/mM/s towardspNPG and cellobiose, respectively. Moreover, Bgl3B was highly effective in converting isoflavone glycosides to aglycones at 37°C within 10 min, with the hydrolysis rates of 95.1%, 76.0%, and 75.3% for daidzin, genistin, and glycitin, respectively. These superior properties make Bgl3B potential for applications in the food, animal feed, and biofuel industries.
