Biological Activity

Description	Crocin (Alpha-Crocin, Gardenia Yellow) is a water-soluble carotenoid pigment of saffron (Crocus sativus L.). It has been used as a spice for flavoring and coloring food preparations, and in Chinese traditional medicine as an anodyne or tranquilizer.

In vitro
In vitro	Crocin can significantly inhibit the proliferation of MCF-7 cells, and induce their apoptosis through mitochondrial signaling pathways including the activation of Caspase-8, upregulation of Bax, the disruption of mitochondrial membrane potential (MMP), and the release of cytochrome c^[1]. Crocin decreases cell viability in DLA (Daltons lymphoma) cells, in a concentration- and time-dependent manner^[2].
Cell Research	Cell lines	MCF-7 cells
	Concentrations	10, 25, 50 µg/ml
	Incubation Time	24 h
	Method	MCF-7 cells were treated with 10, 25, 50 µg/ml Crocin for 24 h and washed with PBS buffer, then fixed in ice-cold 70% ethanol for 15 min. A suspension of 100 µL was taken and incubated with 5 µL propidium iodine (20 µg/ml) and 5 µL annexin V-FITC in the dark for 30 min at room temperature. Finally, 400 µL cold PBS was added to each tube and analyzed by flow cytometry.

In Vivo
In vivo	Crocin exhibits a variety of pharmacological effects in mice including inhibition of skin tumor growth, improvement of learning behavior previously impaired by ethanol, anti-hyperlipidemic effects, therapeutic efficacy for colon adenocarcinomas in rats, anti-atherosclerotic effects and anti-oxidant effects in PC-12 cells by increasing GSH synthesis. For Daltons lymphoma models, The lifespan of ascities tumor bearing mice treated with crocin, are found to be significantly increasing and a significant reduction in solid tumour volume is found in crocin treated animals when compared to that of control animals. Crocin also shows significant impact on hematological parameters, like the hemoglobin count and numbers of lymphocytes^[2]. It has shown that crocin exhibits beneficial effects on many organs including the nervous system, the most studied, gastrointestinal, cardiovascular, genital, endocrine, immune systems, etc. At pharmacological doses it does not harm liver and other organs' function^[3].
Animal Research	Animal Models	Swiss albino mice injected 1 × 10⁶ Daltons lymphoma cells to the peritoneal cavity
	Dosages	10 ml/kg
	Administration	oral

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
