Disease relevance of Agave

• Crude methanol extracts of only Agave sisalana, Birbira and Hypericum revolutum test concentrations up to 500 micrograms/ml showed weak toxicity to brine shrimp [1].

High impact information on Agave

• 1.3':5'-Cyclic AMP was extensively purified from Kalanchoe daigremontiana and Agave americana by neutral alumina and anion- and cation-exchange column chromatography [2].
• Fermentations were carried out in high (300 g l(-1)) and low (30 g l(-1)) sugar concentrations of Agave tequilana juice, in musts obtained from Fiano (white) and Aglianico (red) grapes and in YPD medium (with 270 g l(-1) of glucose added) as a control [3].
• The haemolytic activity of steroidic saponins from Agave sisalana; Smilax officinalis as well as commercial saponin (Riedel De Haën's), was higher than that of triterpenoid ones (Bredemeyera floribunda; Periandra mediterranea) and the Freund's complete adjuvant [4].
• Fresh and cooked agave, Drosophila spp., processing equipment, agave molasses, agave extract, and fermenting must at a traditional tequila distillery (Herradura, Amatitan, Jalisco, México) were studied to gain insight on the origin of yeasts involved in a natural tequila fermentations [5].
• Steroid sapogenins, part XV. The constituents of Agave utahensis var. nevadensis, A. lophantha and A. parasana [6].

Biological context of Agave

• Potential of Agave lechuguilla biomass for Cr(III) removal from aqueous solutions: thermodynamic studies [7].

Anatomical context of Agave

• Exudates (agave juice) from a tequila company were collected periodically, and color, Brix, fructose concentration, and reducing sugars were determined as inulin breakdown took place [8].

Associations of Agave with chemical compounds

• The concentrations of methanol and isobutanol were significantly higher (methanol, p = 0.004; isobutanol, p = 0.005) in the 100% agave (methanol, 297.9 +/- 49.5; isobutanol, 251.3 +/- 34.9) than in the mixed tequilas (methanol, 197.8 +/- 118.5; isobutanol, 151.4 +/- 52.8) [9].
• A phytochemical analysis on these species allowed us the isolation and identification of the steroidal sapogenins hecogenin and diosgenin from Maguey and the hydroxystilbene resveratrol from Bejuco caro [10].
• The soda-ethanol process was superior in terms of delignification and pulp properties in comparison to the soda and ethanol organosolv processes for pulping of agave waste; however, the kraft process gave the best strength properties [11].
• It was found that needle-like calcium oxalate crystals, raphides, are found abundantly in all tissues of Agave tequilana plants; thus, 1 droplet (0.03 ml) of juice pressed from leaves contains 100-150 crystals, 30-500 microm in length, sharpened at both ends [12].
• Three new steroidal saponins, named agamenosides H-J (1-3), and a new cholestane steroid agavegenin D (4) were isolated from the waste residue of fibre separation from Agave americana leaves, together with six known steroids [13].

Gene context of Agave

• Two new steroidal saponins from dried fermented residues of leaf-juices of Agave sisalana forma Dong No. 1 [14].
• Biosynthesis of oligosaccharides and fructans in Agave vera cruz: Part III-biosynthesis of fructans [15].
• Properties of peroxisomal and mitochondrial citrate synthase from Agave americana [16].
• Isolation and characterization of a cDNA encoding a membrane bound acyl-CoA binding protein from Agave americana L. epidermis [17].
• It is not a sulphhydryl protease but seems to be an alkaline "serine" protease with an optimum pH of 7.8-8.0 Agave protease had marked esterolytic activity and with Cbz-Tyr-ONp had an apparent Michaelis constant of 0.0345 -10(-3) M and a V of 1.24 mol substrate/mol enzyme per sec [18].
