Solidago insecticidal activity component analysis
Abstract: This paper based on the three different extraction methods: ethanol refluxing extraction, ultrasonic extraction, extraction of a yellow leaves were extracted. Results showed that ethanol extraction extract insecticidal activity is best, methanol ultrasonic extraction, water extract from the backflow extract. According to the comparison results, use on uv spectrophotometer detection under three different extraction methods of extraction and extract content by HPLC analysis of ultrasonic extraction of methanol extraction liquid, that is the flavonoids, saponins, phenolics, oil plays a key role, these substances are pharmacological activities have anti-inflammatory, antibacterial, diuresis, antitumor activity, according to the food are discussed and summarized. Death As invasive plants solidago canadensis of flood hazards in China quickly on the plant, increase gradually, but research on a flower of chemical composition and the biological activity, lack of system according to a yellow insecticidal activities of chemical composition analysis, it urgently.
