Embodiment 2
[0033] Example 2. This example is to explore the method of Example 1. Take 3 g of lime powder (passed through a No. 4 sieve), add methanol for ultrasonic extraction, add chloroform and shake for 2 times, combine the organic phases, and evaporate to dryness , The residue was dissolved by adding 1 mL of methanol and used as the test solution. Take an appropriate amount of ferulyl tyramide reference substance and add methanol to make a solution containing 1 mg per 1 mL as a reference substance solution. The above two solutions were spotted on the same silica gel G thin-layer plate, using chloroform-methanol (9:1) as the developing agent, unfolded and dried, and then placed under ultraviolet light (254nm) for inspection. The results showed that the test solution had a dark background and could not be clearly identified.
[0034] Therefore, in step (1), the test product is purified. After the sample is extracted with methanol, the sample is extracted twice with petroleum ether by sh...
