example 1
[0014] Example 1. (gastrodia elata is purchased from Yangxian Market, Shaanxi Province)
[0015] Weigh 4.0g of cell wall-breaking enzyme, 3.0g of amylase, 3.0g of pectinase, and 1.0g of protease and mix them for later use; crush the dried Gastrodia elata through a 20-mesh sieve, weigh 200g, and dissolve in 500mL at a concentration of 0.18 mol / L, acetic acid-sodium acetate buffer solution with a pH of 4.8, then add the compound enzyme powder, and stir well; enzymolyze at 50°C for 2 hours, then add 1500 mL of alcohol, and stir thoroughly for 10 minutes; use a pore size of 8 Filter the residue with a micron filter, extract the residue twice with alcohol, combine the extracts and concentrate them into an extract by rotary steaming (temperature at 56°C, speed at 40r / min), and recover ethanol during the concentration process , and finally dry the extract at 80°C to obtain the gastrodin extract.
[0016] The yield of gastrodin determined by HPLC was 0.24%, while the yield of gastrod...

[0017] Example 2. (Gastrodia elata is purchased from the market in Lantian County, Shaanxi Province)
[0018] Weigh 3.0g of cell wall-breaking enzyme, 2.0g of amylase, 2.0g of pectinase, and 1.0g of protease and mix them for later use; crush the naturally dried Gastrodia elata through a 20-mesh sieve, weigh 120g, and dissolve in 300mL at a concentration of 0.12mol / L, acetic acid-sodium acetate buffer solution with a pH of 5.4, then add the compound enzyme powder, and stir well; enzymolyze at 45°C for 1.5 hours, then add 900mL of alcohol, and stir thoroughly for 10 minutes; Filter through a 4-micron filter to remove the residue, extract the filter residue twice with alcohol, combine the extracts and concentrate them with a rotary evaporator (at a temperature of 52°C, at a speed of 30r / min) to form an extract. During the concentration process, ethanol is recovered. Finally, the extract is vacuum freeze-dried to obtain the gastrodin extract.

[0020] Example 3. (Gastrodia elata was purchased from the Yunnan Agricultural Products Expo)
[0021] Weigh 5.0g of cell wall-breaking enzyme, 4.0g of amylase, 4.0g of pectinase, and 1.0g of protease and mix them for later use; crush the naturally dried Gastrodia elata through a 20-mesh sieve, weigh 200g, and dissolve in 500mL at a concentration of 0.16mol / L, acetic acid-sodium acetate buffer solution with a pH of 4.8, then add the compound enzyme powder, and stir well; enzymolyze at 55°C for 2 hours, then add 1500mL of alcohol, and stir for 12 minutes; Filter through an 8-micron filter to remove the residue, extract the filter residue twice with alcohol, combine the extracts, concentrate them into an extract by rotary steaming at a temperature of 60°C, recover ethanol during the concentration process, and finally dry the extract naturally to obtain Gastrodin Extract.
[0022] The yield of gastrodin determined by HPLC was 0.36%, while the yield of gastrodin extracted from the...
