Anti-inflammatory and blood stasis activities of essential oil extracted from Artemisia argyi leaf in animals.

Artemisia argyi leaf is a well-known species in traditional Chinese medicine. However, the anti-inflammatory and activating blood stasis activities of its essential oil (AAEO) have not been explored in vivo. The present study measured the contents of three chemical components by gas chromatography (GC).

[Study on moxa sticks burning temperature-time-space curves].

Objective: To study the burning characteristics of moxa stick.

Methods: A self-designed moxa stick burning temperature measuring device, which was assembled with ALTEC intelligence digital setter and SJ-600 thermocouple, was used to conduct next four experiences: 1) embedding a thermocouple inside a moxa stick to measure peak burning temperature; 2) pulling a thermocouple embedded in the moxa stick at the proper rate to detect combustion stability; 3) elucidating temperature distribution of transverse section by measuring the temperature in the center, radius midpoint and lateral; 4) drawing temperature-time-space curves by pulling the thermocouples in the former three observation points.

Results: The experiment indicated that the burning temperature peak of three-year moxa stick (Hubei Herbal Medicine St.

Firstborn microcrystallization method to prepare nanocapsules containing artesunate.

We developed a novel method to prepare nanocapsules. A solute often crystallizes when its solubility alters from one solvent to another, and its firstborn crystals are used as templates to prepare nanocapsules for the first time, which is called firstborn microcrystallization method. By using this method, the maximum diameter of the nanocapsules including artesunate is about 76 nm, and wrapping state is well.

[Observation on scavenging free radical function of Artemisia burning products].

Objective: To study the pharmacologic action of Artemisia burning products.

Methods: The extractions of Artemisia burning products were determined by spectrophotometry. The scavenging ability of Artemisia burning products on DPPH was evaluated.
