The specific embodiment
Experimentation Herba Houttuyniae volatile oil extraction process technology Study on Conditions
1. the investigation of water absorption rate
Vegetable drug all has the ability of absorption solvent in various degree, and the big young pathbreaker who absorbs the solvent amount influences the effect of extraction.Therefore, bright Herba Houttuyniae is carried out the investigation of water absorption rate.
Get Herba Houttuyniae 1000g, add 2 times of amounts of water, soak after 1 hour.Filter, the weighing medical material, heavy 1150g, then water absorption rate is:
Herba Houttuyniae is fresh medical material, and its water absorption rate is lower, can ignore.
2. amount of water is to the influence of volatile oil collecting amount
If three groups of A, B, C get bright Herba Houttuyniae (herb) 1000g for every group.The water that A group, B group, C group add 1 times, 2 times, 3 times amount respectively extracts volatile oil under the same conditions, measures the volatilization oil mass of extraction in 0.5 to 4.5 hour, the results are shown in Table 1.
Table 1 amount of water is to the influence of volatile oil receipts amount
The result shows: amount of water is that the volatile oil receipts amount of 2 times of groups is higher than 1 times of group and 3 times of groups.Therefore, volatile oil extracts and is advisable with the water that adds 2 times of amounts.
3. extraction time is to the influence of volatile oil collecting amount
The extraction time deficiency of volatile oil then can not be extracted fully; Extraction time too again energy charge man-hour, prolongs the production cycle, therefore is necessary the extraction time of volatile oil is investigated.As can be seen from Table 1, when extraction time was 2.5 hours, gained volatile oil had accounted for more than 95% of total receipts oil mass (in 4.5 hours).Be energy savings, shorten the production cycle, will be decided to be 2.5 hours extraction time.
4. Herba Houttuyniae different parts volatile oil collecting amount and finger printing comparative study
Get fresh fish raw meat grass subterraneous stem (A), the aerial stem of plant (B), each 1000g of leaf (C), add 2 times of water gagings respectively, distillation extraction 2.5 hours.Measurement collection volatile oil situation sees Table 2
Table 2 Herba Houttuyniae different parts volatile oil collecting amount relatively
The result shows: stem portion is collected the volatilization oil mass and is 0.74ml/1000g at most under the fresh fish raw meat meadow, and leaf is partly collected the volatilization oil mass and taken second place and be 0.12ml/1000g, and the aerial stem of plant collects partly that the volatilization oil mass is minimum to be 0.05ml/1000g.
5. the different collecting time volatile oil of Herba Houttuyniae collecting amount research
Get the bright Herba Houttuyniae herb (A) of gathering May, July bright Herba Houttuyniae herb (B), August each 1000g of bright Herba Houttuyniae herb (C) that gathers that gathers, add 2 times of water gagings, distillation extraction 2.5 hours.Measurement collection volatile oil situation sees Table 3
The different collecting time volatile oil of table 3 Herba Houttuyniae collecting amount relatively
Different collecting time Herba Houttuyniae volatile oil collecting amounts have certain difference, through further analyzing, think that different collecting time Herba Houttuyniae volatile oil collecting amounts have the different collecting time subterraneous stems with Herba Houttuyniae of certain difference, relevant with the ratio of aerial parts.The aerial parts large percentage of gathering in May, July, the volatile oil collecting amount is relatively low; The aerial parts ratio of gathering August is less, and the volatile oil collecting amount is higher.
5, the stability study of Herba Houttuyniae volatile oil
If four groups of A, B, C, D get same crowd Herba Houttuyniae volatile oil 5ml for every group and be loaded in the tool plug volumetric flask, do 030501,030,701 two batch of Herba Houttuyniae volatile oil parallel sample simultaneously.37 ℃ of A group sealings are deposited, B group closed chamber is gentlely put, 0-5 ℃ of C group sealing deposited, the D group is opened wide 60 ℃ and deposited, and place respectively 2 months, provide fingerprint atlas detection method and similarity calculating method to measure finger printing and calculate similarity by research unit in every month.The results are shown in Table 4
The different storage requirements of table 4 are to the Herba Houttuyniae volatile oil stability influence
Annotate: the collection of illustrative plates during with 0 month is the similarity situation that contrast is calculated.
"---" represent that sample loses, detect.
Show from each storage requirement testing result of 2 batch samples: Herba Houttuyniae volatile oil adopts that closed chamber is gentle to be put and seal 0-5 ℃ and deposited 2 months, provide fingerprint atlas detection method and similarity calculating method to measure finger printing and calculate similarity by research unit, the quality situation is all stable.
6 Herba Houttuyniae volatile oil quality standard researches
Herba Houttuyniae volatile oil quality standard research data is waited to replenish.
The research of 7 preparing process
7.1 the research of preparing process technical conditions
Compound method: measure Herba Houttuyniae volatile oil 0.5ml, stirring adds down in the 40000 ml Herba Houttuyniae distillates, adds 120g tween 80 stirring and evenly mixing, regulate pH value 5.7～5.9 with 10% citric acid or 10% sodium citrate, add 360g sodium chloride stirring and dissolving, fine straining, embedding, sterilization.
The ratio of Herba Houttuyniae volatile oil and Herba Houttuyniae distillate when 1. preparing.Whether content, other quality index with preparation sample methylnonanone meet the index that existing quality standard is the measurement process conditions.Design A group, B group, C group, D group, E group, F group are respectively the 1ml Herba Houttuyniae volatile oil and add in 10,000 ml, 20,000 ml, 30,000 ml, 40,000 ml, 60,000 ml, the 80000 ml Herba Houttuyniae distillates, preparation Herba Houttuyniae injectio sample, and embedding, sterilization back testing result sees Table 5
Table 5 volatile oil and Herba Houttuyniae distillate different proportion preparation sample quality
The result shows: D group sample quality is more consistent with existing injection, and promptly the 0.5ml Herba Houttuyniae volatile oil adds in the 40000 ml Herba Houttuyniae distillates and is formulated as optimal proportion.With determining ratio more than the different batches Herba Houttuyniae volatile oil repeated authentication.A group, B group, C group are blent preparation with Herba Houttuyniae volatile oil 030501,030701,030801 respectively.The results are shown in Table 6
Table 6 different batches Herba Houttuyniae volatile oil is to determine ratio preparation sample quality
Be formulated as 40,000 ml quality situations from 3 batches of different batches Herba Houttuyniae volatile oils in definite ratio 0.5ml and can illustrate tentatively that this configuration proportion is more stable.
The addition of solubilizing agent tween 80 and adding order when 2. preparing.Whether content, other quality index with preparation sample methylnonanone meet the index that existing quality standard is the measurement process conditions.If A group, B group C group, D group add tween 80 respectively when preparation be 0.2%, 0.3%, 0.4%, 0.5% of amount of preparation.Adding tween 80 before the Herba Houttuyniae volatile oil adding Herba Houttuyniae distillate is 1; Adding tween 80 behind the Herba Houttuyniae volatile oil adding Herba Houttuyniae distillate is 2.Preparation Herba Houttuyniae injectio sample, embedding, sterilization back testing result sees Table 7
The tween 80 of table 7 different proportion and adding sequencing are to the influence of preparation sample quality
The result shows: when adding amount of preparation 0.2% tween 80, preparation sample clarity is all defective, and promptly solubilizing effect can not reach requirement.Add all qualified the least possible additives that add of intravenous injection liquid product of considering of amount of preparation 0.3%～0.5 tween 80 preparation sample, the tween 80 consumption is defined as 0.3% of amount of preparation.The adding sequencing that can get tween 80 from last table is considered the convenience of operation to solubilizing effect and the not obviously influence of preparation sample quality, and volatile oil adds tween 80 after adding in the Herba Houttuyniae distillate again.
