Description

A kind of medicinal plant growth process agent and preparation method thereof and promoting Wite red-rooted salvia root fat Application in soluble components accumulation
Technical field
The present invention relates to a kind of medicinal plant growth process agent, the preparation method of the medicinal plant growth process agent is further related to And promote the method for Wite red-rooted salvia root liposoluble constituent accumulation with it, belong to plant growth technology field.
Background technology
With being filled with for " back to nature " trend, traditional natural plant increasingly has been favored by people.Radix Salviae Miltiorrhizae source In labiate Radix Salviae MiltiorrhizaeSalvia miltiorrhizaBunge. dry root has the work(such as promoting blood circulation and removing blood stasis, inducing meastruation to relieve menalgia Effect is the important medicinal material for treating cardiovascular and cerebrovascular disease, belongs to China and commonly uses large Chinese medicine.Wite red-rooted salvia rootS. miltiorrhiza. f. albaIt is the white flower modification of Radix Salviae Miltiorrhizae, treatment vasculitis effect is very good, causes extensive concern in the industry in recent years, and about such as The effective substance content what is improved in Wite red-rooted salvia root body is rarely reported.It is domestic that Wite red-rooted salvia root is distributed mainly on Shandong, belongs to rare Resources of medicinal plant is put into《Shandong Province's Chinese medicine standard》, Wite red-rooted salvia root liposoluble constituent is that one kind is widely present in rat-tail Diterpene quinone in careless platymiscium is the main active of Wite red-rooted salvia root, including tanshinone (tanshinone I), tanshinone IIA (tanshinone IIA), Tanshinone II B (tanshinone IIB) and Cryptotanshinone ( cryptanshinone) .Wite red-rooted salvia root liposoluble constituent be Radix Salviae Miltiorrhizae improve the heart, liver, lung ischemical reperfusion injury, tissue repair Multiple regeneration adjusts immune response and anti-infective and other effects active principle basis.
Currently, market increasingly increases the demand of white flower red rooted salvia, Wite red-rooted salvia root production scale and cultivated area are not It is disconnected to expand.As Wite red-rooted salvia root dosage increases year by year, medicinal herb grower covets yield and lavishment fertilizer and pesticide, leads to medicinal plant body Interior effective substance content reduces and quality of medicinal material drastically declines.Therefore, adopt an effective measure fundamentally improve quality of medicinal material be Ensure the effective way of this characteristic resources Sustainable Development and Utilization.

Embodiment 15
(1) plant culture and processing
Material to be tested is Wite red-rooted salvia rootS. miltiorrhiza. f. albaSeed source is in the planting bases Radix Salviae Miltiorrhizae GAP. In the same size, healthy salvia seeds are chosen, are seeded in gardens soil and the sandy soil of river sand mixing(1:1, v/v), 25 ± 1 DEG C It sprouts.After third piece blade is grown(Seedling age about 50d), choose the consistent Radix Salviae Miltiorrhizae seedling replanting of growing way and enter equipped with above-mentioned sandy soil Square basin(Per basin sand weight 500g, diameter 10cm, per 1 plant of basin)It is interior, it is placed in artificial climate room, condition of culture:28℃/22℃ (Day night), 14 h of daily illumination, 280-300 μm of m of light intensity-2s-1, relative humidity 60%-65%.The consistent seedling of growing way is chosen, Radix Salviae Miltiorrhizae blade is sprayed with the treatment fluid described in table 2 respectively, sprays and is uniformly covered with drop and not lower drop with leave dual sides It is limited, processing in every 30 days is primary, and 150d carries out the fat-soluble detection being divided into biomass and red sage root after processing.
(2) promote plant strain growth to measure
Plant strain growth is promoted to be indicated using under ground portion fresh weight and dry weight and plant height, with distilled water by white flower when harvest The moisture for being attached to Wite red-rooted salvia root root surface is rinsed and blotted with blotting paper to the root surface of Radix Salviae Miltiorrhizae well, weighs fresh weight.It is then low Drying to constant weight weighs the dry weight of root for temperature.Meanwhile measuring the plant height of Wite red-rooted salvia root aerial part plant.
(3) liposoluble constituent measures
Red sage root and rhizome are cleaned into rear, drying to permanent quality, ground into the fine powder that can be sieved by 380 μm, mixing claims matter Amount.The ratio that 1 mL methanol is added according to 0.1g dry mass is added the methanol of corresponding amount, ultrasonic extraction 45min, it is cooling after from The heart takes supernatant to cross 0.45 μm of miillpore filter, spare.The content of tanshinone is analyzed with high performance liquid chromatography (HPLC), HPLC system is by 1525 binary high performance liquid chromatographs of Waters, 2487 detectors of Waters, Waters Sun Fire C18 chromatographic columns (250mm × 4.6mm, 5 μm), Empower2 chromatography softwares composition.With acetonitrile(A liquid)And volume fraction 0.01% phosphate aqueous solution(B liquid)(pH=2.6)For mobile phase, using binary gradient elutes (table 1).Detection wavelength is 270 nm, Flow velocity 1.0m L/min, 30 DEG C of column temperature.Each sample repeats 3 times, and the tanshinone predominantly detected is Cryptotanshinone, tanshinone I and tanshinone IIA detect the tanshinone standard items sample used and are bought from Nat'l Pharmaceutical & Biological Products Control Institute (Beijing).
(4)Test result
The Salvia miltiorrhiza Growth situation and liposoluble constituent content that are handled using different disposal liquid are detected, as a result such as Shown in the following table 2.As can be seen from the table, plant growth inorganic agent of the present invention can promote Wite red-rooted salvia root to grow, and can also improve its fat Soluble components content, the growth and liposoluble constituent content of the variation of plant growth inorganic agent ingredient and content to Wite red-rooted salvia root Have an impact.Wherein, the inorganic agent best results of embodiment 9.In addition, being compared by embodiment 1 and the experimental result of distilled water As can be seen that being applied alone wood vinegar to Wite red-rooted salvia root growth promotion and liposoluble constituent accumulation effect unobvious.
