Brief Description of Method for Preparation of XueBiJing Injection

XueBiJing injection is prepared from an herb combination of Carthamus tinctorius flowers (Honghua in Chinese), Paeonia lactiflora roots (Chishao), Ligusticum chuanxiong rhizomes (Chuanxiong), Angelica sinensis roots (Danggui), and Salvia miltiorrhiza roots (Danshen). Honghua was first extracted with 30% ethanol and then the extract was diluted with ethanol and centrifuged. The supernatant was reduced followed by dilution with water. After centrifugation, the supernatant was reduced and precipitated with ethanol; after centrifugation again, the supernatant was reduced to yield “H-extract”. Chishao was first extracted with water. The aqueous extract was concentrated under reduced pressure, precipitated with ethanol, and filtered. The filtrate was then reduced and extracted with water-saturated n-butanol. After the n-butanol extract was reduced to dryness, the residual was dissolved in water to yield “C-extract”. Chuanxiong, Danggui, and Danshen were combined and extracted with water. The aqueous extract was treated, in the same way as the preparation of “C-extract”, to yield “CDD-extract”. The preceding H-extract, C-extract, and CDD-extract were combined, diluted with isotonic glucose solution, and fortified with Tween 80. The solution was adjusted to pH 5.8–6.2, ultrafiltered, and sterilized. The finished product of XueBiJing injection was standardized to contain 1.0–1.7 mg/mL concentration of paeoniflorin, 0.2–0.5 mg/mL concentration of hydroxysafflor yellow A, and 0.01–0.20 mg/mL concentration of benzoic acid.
