Description	Safflower yellow is extracted from the flowers of the plant safflower (Carthamus tinctorius) and as the traditional Chinese medicine it has been extensively used for the treatment of cardio cerebrovascular diseases.
In Vivo	Safflower yellow (SY) is the safflower extract and is the one of traditional Chinese medicine. Safflower yellow can promote blood circulation, remove blood stasis, and thereby improve capillary circulation at the site of tissue injury. Safflower yellow is mixtures of a water-soluble chalcone component, in which both hydroxyl safflower yellow A (HSYA) and safflower yellow B (SYB) are the main components. Safflower injection excellently protects the heart by way of improving functions of cardiac contraction and dilation, increasing coronary blood flow, and strengthening the bcl-2 (anti apoptosis gene) protein expression. Safflower yellow alleviates the injured tendon adhesion and inflammatory reaction and promoted the repair of injured tendon^[1].

Solvent & Solubility	In Vitro: DMSO : 20 mg/mL (Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO) Molarity Calculator Dilution Calculator Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol) Mass = Concentration × Volume × Molecular Weight * Concentration _(start) × Volume _(start) = Concentration _(final) × Volume _(final) This equation is commonly abbreviated as: C₁V₁ = C₂V₂ Concentration _(start) C1 × Volume _(start) V1 = Concentration _(final) C2 × Volume _(final) V2 In Vivo: Select the appropriate dissolution method based on your experimental animal and administration route. For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents: To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day. The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution. Protocol 1 Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline Solubility: ≥ 2 mg/mL; Clear solution This protocol yields a clear solution of ≥ 2 mg/mL (saturation unknown). Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL. Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution. Protocol 2 Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline) Solubility: ≥ 2 mg/mL; Clear solution This protocol yields a clear solution of ≥ 2 mg/mL (saturation unknown). Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear. In Vivo Dissolution Calculator Please enter the basic information of animal experiments: Dosage mg/kg Animal weight (per animal) g Dosing volume (per animal) μL Number of animals Recommended: Prepare an additional quantity of animals to account for potential losses during experiments. Please enter your animal formula composition: % DMSO + % + % Tween-80 + % Saline Recommended: Keep the proportion of DMSO in working solution below 2% if your animal is weak. The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE). Calculation results: Working solution concentration: mg/mL Method for preparing stock solution: mg drug dissolved in μL DMSO (Stock solution concentration: mg/mL). In solvent : -80°C, 6 months; -20°C, 1 month (protect from light) The concentration of the stock solution you require exceeds the measured solubility. The following solution is for reference only.

Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution If the continuous dosing period exceeds half a month, please choose this protocol carefully. Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.

Animal Administration
^[1]

Rabbits^[1]
The adult male New Zealand rabbits (body weight 2.0-2.5 kg) are used. Twenty-four rabbits are randomly divided into three groups (per group): sham-operated control (Cont), spinal cord ischemia reperfusion, and treated with safflower yellow. The control group only execute anesthesia and surgical procedures, except for occluding the abdominal aorta. The group is intravenously injected with 2 mL/kg of a solution of 16% (wt/vol) Safflower yellow (1 mL, containing 1.6 mg Safflower yellow), followed by continuous infusion of a total of 5 mL/kg through the right femoral vein at the moment of reperfusion beginning after 40 minutes of the abdominal aorta occlusion. The same volumes of 0.9% saline solution are administrated in control and groups. Blood samples are obtained at the end of 0 hour, 4 hours, 12 hours, 24 hours, and 48 hours after reperfusion, and the plasma is separated and stored at -80°C for further analysis. All animals are sacrificed 48 hours after reperfusion and are rapidly perfused with 0.9% sodium chloride, and the L2-5 segments of the spinal cord are quickly removed. The L2-3 segment in each animal is used for western blot, and the other segment (L4-5) is immersed into 10% neutral formaldehyde for 2-3 days and is used for morphology analysis^[1].
