Conclusion The matrine liposomes with high entrapping efficiency can be prepared by ammonium sulphate gradien method. 结论采用硫酸铵梯度法可制得包封率较高的苦参碱脂质体。
The effect of ammonium phosphates was better than super-phosphate on increasing grain yield in lime concretion black soil, but the results were reversed for grain quality. 高氮和硫酸铵处理能提高强筋小麦的品质。
