闰年霉素A4晶体及其制备方法
摘要：
本发明公开了一种闰年霉素A4晶体、其制备方法及其药用组合物。所述晶体在X-射线衍射图谱中下述2θ角具有特征峰：7.6°、8.2°、10.2°、14.6°、15.2°、18.9°、20.0°、20.4°±0.2。本发明得到的闰年霉素A4晶体颗粒均匀、稳定性好，便于分装和保存。本发明所提供的闰年霉素A4晶体的制备方法简单，可操作性强，适合工业化生产。
摘要（英）：

The invention discloses a lipiarmycin A4 crystal and a preparation method and a medicinal composition thereof. The crystal has the characteristic peaks at 2-theta angles in an X-ray diffraction pattern: 7.6 DEG, 8.2 DEG, 10.2 DEG, 14.6 DEG, 15.2 DEG, 18.9 DEG, 20.0 DEG, and 20.4 DEG+/-0.2. The obtained lipiarmycin A4 crystal is uniform in particles, good in stability, and easy to subpackage and preserve. The lipiarmycin A4 crystal preparation method provided by the invention is simple, high in maneuverability, and suitable for industrialized production.
