The utility model discloses an airlift bioreactor for amplification culture of taxus cuspidata stem cells. The airlift bioreactor comprises a tank body, a rotatable spiral guide cylinder and a microbubble generator, the microbubble generator is arranged in the middle of the bottom of the tank body, and the rotatable spiral guide cylinder is arranged in the tank body and fixed above the microbubble generator. According to the utility model, the micro-bubble generator is arranged at the air vent at the bottom of the bioreactor tank body, the rotatable spiral baffle is designed in the guide cylinder, and the spiral baffle in the guide cylinder is driven to rotate by utilizing kinetic energy generated by uniform rising of micro-bubbles through a micro-bubble group generated by the micro-bubble generator, so that fluid forms vortex flow in a spiral channel; and meanwhile, the collision probability of the microbubbles is reduced under the action of centrifugal force. Through a non-mechanically driven dynamic mixing mode, the oxygen transfer and mass transfer bottleneck in a high-viscosity culture system is effectively solved, and efficient reaction equipment is provided for large-scale culture of plant cells.

The invention discloses a taxus chinensis component-containing essential oil capable of dredging pain, and relates to the technical field of essential oil preparation, the taxus chinensis component-containing essential oil comprises water, glycerin, a lavender extract, a ligusticum wallichii root extract, a taxus cuspidata leaf extract, a chamomile extract, sodium hyaluronate and a salvia miltiorrhiza extract, and all the raw materials are uniformly mixed. According to the taxus chinensis essential oil, beneficial components in taxus chinensis and other materials are extracted in a distillation mode, waste of taxus chinensis is reduced, meanwhile, the lavender extract, the ligusticum wallichii root extract, the chamomile extract, the sodium hyaluronate and the salvia miltiorrhiza extract are mixed with the taxus cuspidata leaf extract, the effect of taxus chinensis is amplified, and the effect of the essential oil is better.

The present application relates to the technical field of daily chemical products, and specifically discloses a kind of organic silicon quaternary ammonium salt microemulsion and its preparation method and application.The microemulsion includes, by weight parts: polysiloxane quaternary ammonium salt-16 5-20 parts, tridecanol polyether-12 2-8 parts, northeast taxus chinensis leaf extract 0.5-1 part, surfactant 0.5-5 parts, thickening agent 0.1-2 parts, pH responsive microcapsule and the rest deionized water;The pH responsive microcapsule includes polyquaternary ammonium salt-33, squalane and hydrolyzed keratin, wherein polyquaternary ammonium salt-33 forms shell, squalane constitutes oil core, and hydrolyzed keratin is coated inside.The preparation method includes pre-emulsification, oil phase mixing, initial emulsion formation, high-pressure microjet homogenization.The microemulsion is used for shampoo, and there is no irritation to scalp, with instant conditioning and long-acting repair effect.

The invention discloses a taxus cuspidata TcuJAZ3 gene and application of the taxus cuspidata TcuJAZ3 gene in increasing the yield of paclitaxel, and belongs to the field of gene engineering. The low-temperature response gene TcuJAZ3 is cloned from taxus cuspidata, expression of enzyme genes in almost all paclitaxel biosynthetic pathways is remarkably activated by overexpression of the TcuJAZ3, the TcuJAZ3 is a key regulatory factor of the paclitaxel biosynthetic pathways, and the paclitaxel content in transgenic leaves is remarkably increased. The TcuJAZ3 gene can be used as a key target for regulating and controlling the paclitaxel content, and a new way is provided for culturing a new variety of taxus chinensis with high paclitaxel content and obtaining paclitaxel by utilizing gene engineering and cell engineering.
