摘要:
The invention relates to a composition containing total triterpenoid sapogenins extracted from bamboo, the preparation method and use thereof. These total triterpenoid sapogenins are extracted from many parts of bamboo such as bamboo shavings in Gramineae by CO2 Supercritical Fluid Extraction technique. In the extract, the content of total triterpenoid sapogenins is 10-90%, while the contents of friedelin and lupenone are 5-35% and 1-10%, respectively. The extract in the invention has good physiological and pharmacological activities such as anti-free radical, anti-oxidation, anti-tumor and anti-hypertension. It can be used in medicines or functional foods for the treatment or prevention of cardiovascular and cerebrovascular diseases and tumor. It is also useful in cosmetics field.
摘要:
An electrical connector (1) mounted on a circuit board is provided for mating with an electric device. The electrical connector includes a dielectric housing (10) having a terminal passage (16), a pair of conductive contact elements (20) received in the housing, and a fixing pad (30) connecting the circuit board. Each conductive contact element includes a base portion (21) positioned in the terminal passage, a tail portion (22) arranged on one side of the housing for connecting with a circuit board, a contacting portion (24) which serves for contacting the electric device, and a spring portion (23) connecting the contacting portion resiliently to the base portion. The fixing pad is fixed to the other side of the housing for providing balanced force acted on the electrical connector during mating with the electric device.
