Analysis of carbohydrates in the local rice beer reveals that amount of carbohydrate in the beer depends on the variety office and herbs. Laboratory analyses for qualitative estimation of carbohydrate in beer are: Benedict’s test, Molisch’s test and iodine test; while quantitative estimation of carbohydrate in beer are phenol-sulfuric acid assay [72], 3,5-dinitrosalicylic acid test [4]. Glucose is used as a standard for the quantitative analysis [4, 72].

Diphyllin is a major glycoside compound present in C. collinus plant. Anjaneyulu et al. [27] reported a new diphyllin diglycoside from C. collinus heartwood. From the methanolic extract, the CHCl3 soluble fraction was treated with benzene and the benzene-insoluble residues were crystallized (CHCl3–MeOH) as colorless plates. As the isolated fraction of methanol extract showed Molisch’s test as positive, the glycoside was hydrolyzed and the aglycone was identified as diphyllin through spectral analyses. Two glycosides of diphyllin containing 2,3- and 3,4-di-O-methyl xyloses were identified for this plant. Similarly, 4-O-(3″-O-methy1-β-d-glucopyranosyl)diphyllin and Cleistanthoside-A were successfully isolated and identified in C. collinus fruits [28].
Biogenic synthesis and characterization of silver nanoparticles using aqueous leaf extract of Scoparia dulcis L. and assessment of their antimicrobial property
Published in Drug and Chemical Toxicology, 2020
Qualitative phytochemical analysis of the S. dulcis extract has been performed using the methodology described by Parekh and Chanda (Parekh and Chanda 2008) for determining the presence of alkaloids (Mayer’s, Dragendorff’s reagent), flavonoids (Shinoda alkaline reagent), phenolic compounds (lead acetate), terpenoids (chloroform/H2SO4), steroids (Lieberman–Burchard test), tannins (FeCl3 test), carbohydrates (Molisch test), amino acids/proteins (Ninhydrin reagent), and cardiac glycosides (Killer killiani) (Harborne 1976, Dey and Harborne 1987). The results of these tests have been expressed qualitatively as positive (+) or negative (−).
