[Effect of different processing conditions on content of myrisiticin, volatile oil and fatty lipid in semen Myristicae].

The effect of different processing conditions on contents of myrisiticin, volatile oil and fatty lipid in Semen Myristicae was studied by orthogonal design. The result shows that these processing conditions could not influence the contents of myrisiticin, volatile oil and fatty lipid in the processed products of Semen Myristicae, suggesting that processing does not necessarily lower toxicity.

In this paper, the contents of total flavonoids, essential oil, tannin, trace elements along with bacteriostatic action in Sophora Powder have been measured. These studies present a scientific evaluation on the quality of Sophora Powder.

[Pharmacognostic studies on Sanguis lignum Dracaenae cochinchinensis].

The resin of Dracaena cochinchinensis has been used as the substitute for Chinese drug Xuejie (Sanguis Draconis) for 20 years in China. The pharmacological, toxicological and clinical studies have shown that the former is similar to the latter in effects, and can be used as a substitute for the latter. This paper deals with the resources, morphological and histological characters, chemical and physical analysis of Sanguis Lignum Dracaenae Cochinchinensis.

[Quality standards of huanglian jiedu pills].

TLC and microscopy have been used in the qualitative study of Huanglian Jiedu Pills. The contents of berberine hydrochloride and baicalin in these Pills have been determined. The proposed method can be used to control the quality of Huanglian Jiedu Pills.

[Effect of artesunate transdermal preparation on Plasmodium cynomolgi].

Artensunate transdermal preparation at 5, 10, or 15 mg/kg, bid, for 3 days applied locally on the shaved skin of the back of monkeys showed reliable therapeutic effects on Plasmodium cynomolgi, but recrudescence of the parasites was not controlled. If some azone was added in the artesunate transdermal preparation at the dosage of 5 mg/kg, bid, for 3 days, the parasitemia of Plasmodium cynomolgi could be cleared and recrudescence prevented, thus, the antimalarial effects was enhanced.
