Zanthoxylum nitidum var. tomentosum is used as an adjuvant to promote blood circulation and remove stasis. However, the mechanisms of improving circulation and other biological activities of Z. nitidum var. tomentosum are still unclear. Plasminogen activator inhibitor-1 (PAI-1) regulates the plasminogen activation system through inhibition of tissue-type and urokinase-type plasminogen activators (tPA and uPA). PAI-1 has been linked to fibrin deposition that evolves into organ fibrosis and atherosclerosis. |

Spasmolytic activity of Toddalia asiatica Var. floribunda.[Pubmed:12164278]
Phytother Res. 2002 May;16(3):281-2.
The spasmolytic activity of the aerial parts of Toddalia asiatica var. floribunda (family Rutaceae) was evaluated. The ethanol extract exhibited significant spasmolytic activity and was then partitioned into five fractions. The activity was found to be concentrated only in the hexane and chloroform fractions. This activity was shown not to be due to the coumarins, Toddalolactone and toddanone, as was previously thought.

Yakugaku Zasshi. 1991 Jul;111(7):376-85.
It is well known that Toddalolactone (1) is a main component of Toddalia asiatica (L.) Lam. (T. aculeata Pers.) (Rutaceae). However, supercritical fluid (SCF) extraction of the plant by using CO2 showed that a main component of the extract was not 1, but aculeatin (2), a coumarin having an epoxy ring on the side chain. The same result was obtained from Soxhlet extraction by using aprotic solvents. On the other hand, Soxhlet extraction by using methanol yielded 13, corresponding to a methanol adduct of 2, as an additional component, which was able to be also produced in 50.2% yield only by heating pure 2 in methanol, indicating that the epoxy ring in 2 can be easily attacked by a weak nucleophile like methanol. These facts strongly suggested that 1, corresponding to the hydrate of 2, was an artefact derived from 2 during extraction. SCF extraction under various conditions was examined in detail by quantitative analyses of 1 and 2 by high performance liquid chromatography and the optimum condition extracting the both components was found to be at 40 degrees C and at 300 kg/cm2. The condition was applied to the plant treated with aqueous sodium hydrogen carbonate in order to remove any acidic substances and 1 was still detected in the extract. Thus, it is conclude that 1 should be a genuine natural coumarin but that previous isolation of 1 as a main component resulted in an isolation of an artefact derived from 2. SCF extraction was suggested to be a useful extraction method.
