A water soluble organic extract from Tanshen (Radix salviae miltiorrhizae)wasfound to inhibit cyclic AMP phosphodiesterase(cAPD) from all tissues examined.Enzymes from uterus, brain, urinary bladder and lung of rabbit were more sensitiveto the inhibitor. At the concentration of several micrograms per mililitter, theextrac tinhibited the enzyme markedly, and when added to a concentration of 1~2mg/ml, they inhibited the enzyme activity completely. The inhibiting characteristicstudies indicated that its inhibition...

A water soluble organic extract from Tanshen (Radix salviae miltiorrhizae)wasfound to inhibit cyclic AMP phosphodiesterase(cAPD) from all tissues examined.Enzymes from uterus, brain, urinary bladder and lung of rabbit were more sensitiveto the inhibitor. At the concentration of several micrograms per mililitter, theextrac tinhibited the enzyme markedly, and when added to a concentration of 1~2mg/ml, they inhibited the enzyme activity completely. The inhibiting characteristicstudies indicated that its inhibition was of uncompetitive and irreversible pattern.The aqueous extract from Tanshen was chromatographed on silica G thin layerplates giving 16 organic spots which all proved to be effective in inhibiting cAPD.The most potent inhibiting fraction was also separated with organic solvent, anddesignated as fraction 4, of which the predominant component was spot 13, with 50percent inhibition at 8μg/ml. Its inhibition was 32 times more effective thantheophylline when tested with cAPD from rabbit brain.Some physiological effects of the aqueous extract of Tanshen in vivo are discussedin terms of its action as an inhibitor of cAPD.

丹参水溶性提出物发现有抑制体外环腺苷酸磷酸二酯酶(cAPD)的作用。这种抑制对被试动物和组织具有普遍性,但以家兔子宫、大脑、膀胱和肺中的cAPD 最敏感。每个测定含微克量级的丹参水溶性有机物即可产生明显抑制作用,剂量增加到1~2毫克出现完全抑制。兔脑匀浆上清液中的蛋白质对其cAPD 有保护作用。酶作用动力学的研究指出,丹参水溶性成分对兔脑cAPD 表现典型的非竞争性抑制,并且是不可逆性抑制。丹参水溶性提出物用硅胶G 薄板层析可检出16个斑点。用有机溶剂分离的部分4(主要为斑点13)对兔脑cAPD 的抑制力最强,其50%抑制量为8微克/毫升,比茶碱强32倍。丹参水溶性成分可能通过抑制cAPD 而发挥某些生理效应。

Piroxicam involved in plasma was determined by HPLC. The acidified plasma (pH=4) was extracted by using diethyl ether, with l-(2-pyridylazo)-2-naphthol as an internal standard. The organic extract was reduced to dryness, the resultant residue was redissolved in methanol, and an aliquot of this solution was then chromatographed on a cyano-column, using a mobile phase of CH_3OH-0.1mol/LKH_2PO_4 (45:55) pH3.0. The sensitivity of the method was 0.05μg/ml of plasma level. The linearity was demonstrated...
