Abstract
The invention relates to a lamiophlomis herba drying method, which is characterized by comprising piling, freezing and drying. The contents of main active ingredients total saponins, total flavonoids and ethanol-soluble extract in prepared lamiophlomis are high.
Description
Invention field
The present invention relates to medicine method for making, particularly a kind of drying means of lamiophlomis rotata, belongs to medical technical field.
Background technology
Lamiophlomis rotata is the dry aerial parts of Labiatae lamiophlomis rotata platymiscium lamiophlomis rotata.It has promoting blood circulation and hemostasis, effect of wind-expelling pain-stopping, and for traumatic injury, traumatism and bleeding, arthralgia due to wind-dampness, grasserie etc.Mainly contain the active ingredients such as flavonoids, iridoids, saponins.
The lamiophlomis rotata ground such as being grown in Gansu, Qinghai, Chuan Xi plateau, Tibet that mainly distributes, collecting season is annual 8, September.Because lamiophlomis rotata growth area mostly is economically underdeveloped area, the not unified processing conditions of gathering, the various places personnel that gather mostly also are local resident, so cause Post-harvest processing method to differ, quality fluctuation is larger.Adopt which kind of method dry better, not yet report at present.
Summary of the invention
The object of this invention is to provide a kind of drying means of lamiophlomis rotata, the lamiophlomis rotata that the method is dry, the main total saponin(e of active ingredient, general flavone and alcohol extract content are high.
A drying means for lamiophlomis rotata, banks up, freezing, dry.Wherein, banking up is the 2-5 days that banks up; Freezing is to be refrigerated to freeze; Dry is dry or dry or dry.
Further illustrate usefulness of the present invention below by test example, test example is intended to further illustrate usefulness of the present invention, but not limitation of the present invention.
To, with a collection of fresh lamiophlomis rotata, process by the following method.
1) dry: be put in shady and cool ventilation place, spread out and dry;
2) dry: 80 DEG C of following oven dry;
3) the freezing oven dry of banking up: bank up 2 days, be refrigerated to-5 DEG C to freezing, take out, 80 DEG C of following oven dry;
One, n-butanol extracts the content comparison of total saponin(e
Each 0. 5 g of sample, accurately weighed respectively, puts in 150mL conical flask, and precision adds people's n-butanol 100mL, jam-pack, and cold soaking 1h, filters rapidly, and precision measures subsequent filtrate 20mL, puts in the evaporating dish that is dried to constant weight.After water bath method, in 150 DEG C of dry 3h, put cooling 30min in drier, accurately weighed, to obtain final product.The results are shown in Table 1.
Table 1 n-butanol extracts the content comparison (%, n=3) of total saponin(e
| Medicinal material | Dry | Dry | The freezing oven dry of banking up |
| Total saponin(e | 2.27 | 1.44 | 4.27 |
Found out by table 1, lamiophlomis rotata is banked up freezing oven dry total saponin content higher than drying, drying.
Two, the content side of general flavone compares surely
1, instrument and reagent
Instrument: the visible spectrophotometer of ultraviolet one; Electronic balance; Control substance of Rutin.
2, detect determining of wavelength
After the colour developing of control substance of Rutin aluminum nitrate, have absorption maximum at 500-510nm wavelength place, in conjunction with document, test selects 500nm for detecting wavelength.
3, the preparation of reference substance solution
Precision takes the control substance of Rutin 10mg to constant weight at 120 DEG C of drying under reduced pressure, puts in 50mL measuring bottle, adds 70% ethanol 35mL, puts low-grade fever in water-bath and makes to dissolve, and lets cool, and adds 70% ethanol to scale, shakes up, and obtains (in every mL, containing anhydrous rutin 0.2mg).
4, test sample preparation and assay
Get the each 0.1g of lamiophlomis rotata medicinal material, accurately weighed, put in l00mL volumetric flask, add 70% ethanol 70mL, after jolting, add ethanol to scale, place lh, filter rapidly with dry filter, precision measures subsequent filtrate 6mL, put in 25mL volumetric flask, add 5% sodium nitrite solution 1mL, mix, place 6min; Add 10% aluminum nitrate solution lmL, shake up, place 6min; Hydro-oxidation sodium test solution 10mL, then add water to scale, shake up, place 15min.Measure trap according to AAS at 500nm wavelength place, calculate, to obtain final product.The results are shown in Table 2.
The content comparison (%, n=3) of table 2 general flavone
| Medicinal material | Dry | Dry | The freezing oven dry of banking up |
| General flavone content | 5.34 | 5.13 | 6.96 |
Found out by table 2, the lamiophlomis rotata freezing oven dry of banking up, the content of general flavone is high.
Three, the content side of ethanol soluble extractives compares surely
Measure according to the hot dipping under Chinese pharmacopoeia ethanol soluble extractives determination method (annex X A) item, make solvent with 70% ethanol, the results are shown in Table 3.
The content comparison (%) of table 3 ethanol soluble extractives
Found out by table 3, the lamiophlomis rotata freezing oven dry of banking up, the content of ethanol soluble extractives is high.
Detailed description of the invention
embodiment 1
Get fresh lamiophlomis rotata, bank up 2 days, be refrigerated to below-5 DEG C, dry.
embodiment 2
Get fresh lamiophlomis rotata, bank up 5 days, be refrigerated to-20 DEG C to freezing, 60 DEG C of oven dry.
embodiment 3
Get fresh lamiophlomis rotata, bank up 4 days, be refrigerated to-30 DEG C to freezing, take out, dry.
Claims (1)
1. a drying means for lamiophlomis rotata, is characterized in that banking up, freezing, dry; Wherein, banking up is the 2-5 days that banks up; Freezing is to be refrigerated to freeze; Dry is dry or dry or dry.
