A composite medicine in the form of solution for treating cardiovascular and cerebrovascular diseases features that it contains high-purity wild-scutelloside and pH regulator proportionally and the content of said high-purity wild-scutelloside can be stabilized for at least 18 months.

The invention discloses a cultivation method for inducing scutellaria baicalensis hairy root based on agrobacterium rhizogenes infection, which uses an agrobacterium rhizogenes bacteria liquid to infect root of a scutellaria baicalensis explant and induces the scutellaria baicalensis explant to form a hairy root, the scutellaria baicalensis hairy root presents yellow hairy on a MS solid medium, so that scutelloside can be stably synthesized, an ITS sequencing is performed and the hairy root can be identified as the scutellaria baicalensis hairy root of a scutellaria. Then seed selection is performed for further in a seed selection medium and a cultivation condition can be optimized to select lines which raise the content of active ingredient scutelloside used for hairy root traditional Chinese medicines. Hairy root can be obtained through scutellaria of a scutellaria introduced by agrobacterium rhizogenes, wherein the inductivity can reach 10 - 40%, the obtained scutellaria baicalensis hairy root presents yellow hairy which is capable of stably synthesizing scutelloside. According to the invention, the scutellaria baicalensis hairy root of a scutellaria is cultivated on the optimized medium, the growth is rapid and the biomass can be increased for 23 -35 times in 30 - 35 days, and the cultivation is performed under the dark conditions. The invention has the characteristics of low energy consumption and low cost, which is suitable for industrialization production.

A quality test method for the Chinese medicine 'Jinsangqingyin pill' features that the paeonol and scutelloside are qualitatively discriminated and the content of paeoniflorin is measured by high-effect liquid-phase chlomatography.

The invention discloses a method for extracting scutelloside and scutellarin from baikal skullcap root. The method comprises the following steps of: (1) performing ultrasonic extraction on a solvent; (2) adsorbing Fe3O4 magnetic nanoparticles; and (3) performing desorption. The method is simple and rapid; separation of an absorption carrier and a feed liquid can be realized by additionally applying a magnetic field; scutelloside and scutellarin can be eluted selectively through different eluents, so that loss of raw materials and energy consumption is avoided, and cost is reduced effectively; and Fe3O4 magnetic nanoparticles can be used circularly, so that cost can be saved effectively.
