Scope

Scope: This document specifies the requirements, test methods, acceptance criteria, and quality assurance period for 0.015% 28-Kinetin Microencapsulated Suspension, as well as its marking, labeling, packaging, and storage and transportation. This document applies to 0.015% 28-Kinetin Microencapsulated Suspension manufactured from 28-Kinetin active ingredient, polymer encapsulation materials, and necessary additives. Main technical content: The method for determining the mass fraction of 28-Kinetin in the sample is as follows: The sample is dissolved in methanol and subjected to a derivatization reaction with phenylboronic acid (phenylboronic acid methanol solution) at 80°C for 1 hour. The sample is separated by reverse-phase high-performance liquid chromatography using an acetonitrile-water mobile phase and a stainless steel column filled with C18 with an ultraviolet detector (222 nm) for quantitative analysis. Reagents and solutions: Methanol: chromatographically pure; Acetonitrile: chromatographically pure; Water: freshly distilled and double-distilled water; 28- Kinetin standard sample: with a known mass fraction of ω≥97.0%; Phenylboronic acid methanol solution: 1.0 mg/mL. Instrumentation: High-performance liquid chromatograph with a variable-wavelength ultraviolet detector. Chromatographic column: 250 mm×4.6 mm (i.d.) stainless steel column filled with ODS-C18T (5 μm) packing material. Micro-injection pump: 100 μL. Ultrasonic cleaner. High-performance liquid chromatography operating conditions: Mobile phase: acetonitrile + water = 80+20 (V/V), filtered through a 0.45 μm filter and degassed; Flow rate: 1.0 mL/min; Column temperature: room temperature (temperature variation not exceeding 2°C); Detection wavelength: 222 nm; Injection volume: 10 μL; Retention time: approximately 15.5 minutes for 28-Kinetin. The above-mentioned operating parameters are typical. For different instruments, the given operating parameters can be adjusted appropriately to achieve the be
