Abstract:
1. A composition comprising: a. one or more indolequinazoline alkaloids; b. butylated hydroxytoluene; and c. one or more solvents and/or one or more carriers; wherein: (i) the combined concentrations of the one or more indolequinazoline alkaloids in the composition is at least 0.02 μg/ml and the concentration of butylated hydroxytoluene is at least 0.01 mg/ml; and/or (ii) the sum of the dry weights of (a) and (b) in the composition is at least 10 percent of the weight of total solids in the composition; and/or (iii) the quotient of the light absorption of the composition at 550 nanometers divided by its absorption at 270 nanometers is less than or equal to 0.01; and/or (iv) the quotient of the light absorption of the composition at 450 nanometers divided by its absorption at 400 nanometers is less than or equal to 0.1.
