Abstract
The invention relates to a method for drying common lamiophlomis. The method comprises the following steps: taking fresh common lamiophlomis, stewing and drying the common lamiophlomis. The main active ingredients total saponins and general flavone in the prepared common lamiophlomis are high in content.
Description
Invention field
The present invention relates to medicine method for making, particularly a kind of drying means of high activity Radix Lamiophlomidis Rotatae, belongs to medical technical field.
Background technology
Traditional Chinese medicine drying has very long history in China, the Chinese herbal medicine of drying can keep certain medicinal ingredient and be difficult for putrid and deteriorated, the dry important measures as guaranteeing Chinese herbal medicine quality, be a requisite technical process in Chinese herbal medicine processing, dry method will directly affect the quality of product.
Radix Lamiophlomidis Rotatae is the dry aerial parts of Labiatae Radix Lamiophlomidis Rotatae platymiscium Radix Lamiophlomidis Rotatae.It has promoting blood circulation and hemostasis, the effect of wind-expelling pain-stopping, and for traumatic injury, traumatic hemorrhage, rheumatic arthralgia, grasserie etc.Mainly contain the effective ingredient such as flavonoid, iridoids, saponins.
The drying means of Chinese Pharmacopoeia regulation Radix Lamiophlomidis Rotatae be autumn flowering fruit bearing stage tap, clean, dry.
Summary of the invention
The drying means that the object of this invention is to provide a kind of Radix Lamiophlomidis Rotatae, the Radix Lamiophlomidis Rotatae that the method is dry, main effective ingredient total saponins and general flavone content are high.
The present invention is achieved in that
A drying means for Radix Lamiophlomidis Rotatae, get fresh Radix Lamiophlomidis Rotatae heap vexed after, dry.
The drying means of a kind of Radix Lamiophlomidis Rotatae of the present invention, wherein, piling vexed is the vexed 2-5 days of heap.
The drying means of a kind of Radix Lamiophlomidis Rotatae of the present invention, wherein, heap disintegration method can replace heap vexed by transportation.
So far completed the present invention.Radix Lamiophlomidis Rotatae main active flavonoid and saponins content that the inventive method is dry are high, and then known, and clinical efficacy is good.
Below by test example, further illustrate usefulness of the present invention, 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 Radix Lamiophlomidis Rotatae, process by the following method.
1) dry: fresh Radix Lamiophlomidis Rotatae, put under sunlight and spread out and dry;
2) pile vexed drying: fresh Radix Lamiophlomidis Rotatae, pile vexed 3 days, put under sunlight and spread out and dry.
One, the content comparison of n-butanol extraction total saponins
Each 0. 5 g of sample, accurately weighed respectively, puts in 150mL conical flask, and precision adds people's n-butyl alcohol 100mL, jam-pack, and merceration 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 ℃ of dry 3h, put cooling 30min in exsiccator, accurately weighed, obtain.The results are shown in Table 1.
The content comparison (n=3) of table 1 n-butanol extraction total saponins
| Medical material | Dry | Pile after vexed and dry |
| Total saponins (%) | 1.94 | 3.15 |
By table 1, found out, Radix Lamiophlomidis Rotatae " pile vexed then dry " total saponin content is apparently higher than drying.
Two, the content side definite proportion of total flavones
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, at 500-510nm wavelength place, have absorption maximum, in conjunction with document, test and Selection 500nm is for detecting wavelength.
3, the preparation of reference substance solution
Precision takes the control substance of Rutin 10mg to constant weight at 120 ℃ of drying under reduced pressure, puts in 50mL measuring bottle, adds 70% ethanol 35mL, puts slight 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 each 0.1g of Radix Lamiophlomidis Rotatae medical material, accurately weighed, put in l00mL volumetric flask, add 70% ethanol 70mL, after jolting, add ethanol to scale, place lh, with dry filter, filter rapidly, 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.According to spectrophotography, at 500nm wavelength place, measure trap, calculate, obtain.The results are shown in Table 2.
The content comparison (n=3) of table 2 total flavones
| Medical material | Dry | Pile after vexed and dry |
| General flavone content (%) | 5.22 | 6.34 |
By table 2, found out, Radix Lamiophlomidis Rotatae " pile vexed then dry " general flavone content is higher than drying.
Three, pile the dry general flavone content comparison of vexed rear distinct methods
To pile vexed 2 days with a collection of fresh Radix Lamiophlomidis Rotatae, dry respectively, dry and 60 ℃ of following oven dry.
Measure respectively general flavone content and the results are shown in Table 3
The content comparison (n=3) of the dry total flavones of the vexed rear distinct methods of table 3 heap
| Medical material | Pile after vexed and dry | Pile after vexed and dry | Pile vexed post-drying |
| General flavone content (%) | 6.37 | 6.33 | 6.34 |
By table 2, found out, the vexed rear distinct methods of Radix Lamiophlomidis Rotatae heap is dry, and general flavone content is basically identical.
The specific embodiment
embodiment 1
Get fresh Radix Lamiophlomidis Rotatae, pile vexed 2 days, dry.
embodiment 2
Get fresh Radix Lamiophlomidis Rotatae, pile vexed 3 days, dry.
embodiment 3
