| overview | the chemical structural formula of 3-indole formaldehyde is as follows, its molecular formula is C9H7NO, and its relative molecular weight is 145.161. It has been reported that 3-indole formaldehyde has certain antibacterial, anti-inflammatory and anti-tumor biological activities. In addition, 3-indole formaldehyde is also an important pharmaceutical and organic intermediate, which can be used to synthesize many compounds with physiological and pharmacological activities, such as indole acetic acid, indomethacin, etc. At present, one of the main sources of 3-indole formaldehyde is chemical synthesis, but the chemical synthesis process is more complicated, involving many toxic and harmful reagents, and the yield is limited; another way is to extract from natural plants, and there is also the problem of cumbersome extraction process and low yield. At present, the method of extracting 3-indole formaldehyde from ascidians has not been reported. |
