The chloroform extract demonstrated significant antinociceptive activity with inhibition rates of 44.7 % at 5.9 mg/kg and 50.4 % at 17.7 mg/kg. In the hot plate test, latency times increased from 15.6 ± 4.1 s to 47.3 ± 6.4 s at 5.9 mg/kg and from 16.3 ± 3.8 s to 49.8 ± 7.6 s at 17.7 mg/kg. This same chloroform extract also showed anti-inflammarotory activity by reducing xylene-induced ear oedema with inhibition rates of 45.48 % at 5.9 mg/kg and 51.46 % at 17.7 mg/kg. While active, the chloroform extract exhibited toxicity with an LD50 of 89.65 mg/kg.

What are the pharmacological activities of Aconitum sinomontanum?

This plant has significant pharmacological activities including analgesic, anti-inflammatory, and antinociceptive properties. These biological actions allow the species to effectively mitigate various types of pain and physiological distress. Scientific studies indicate that its chemical constituents interact with specific neural pathways to reduce the sensation of discomfort. Furthermore, the plant's ability to decrease swelling and redness demonstrates its potent anti-inflammatory potential. By modulating pain perception through antinociceptive mechanisms, it serves as a subject of interest for medicinal research.

According to a study published by "Planta medica", the C19 diterpenoid alkaloid lappaconitine (LA) from Aconiutum sinomontanum nakai acts as an inhibitor of tetrodotoxin-sensitive, voltage-dependent sodium channels. At a stimulation frequency of 2.5 Hz, the time constant for the onset of LA effects was tau = 56 +/- 29 min, whereas for its metabolite DLA it was tau = 14 +/- 8 min. These compounds exerted a significant negative inotropic action at 0.06 microM for LA and 0.2 microM for DLA. Asystolia of right atria occurred at 4.5 microM for LA and 10 microM for DLA. Furthermore, preincubation with 0.3 microM LA prevented arrhythmia induced by aconitine or ouabain. Lappaconitine is concluded to be a naturally occurring compound with class-I antiarrhythmic action.

The primary pharmacological activities of this plant are shown in the list below.

  • analgesic

What side effects this plant can have?

This plant can cause severe cardiovascular complications including asystolia, negative inotropic action, and various life-threatening toxic effects due to its high concentration of aconitine alkaloids. The presence of these alkaloids interferes with sodium channels in the heart, leading to dangerous rhythm disturbances. As the toxins circulate, they exert a negative inotropic action that significantly weakens the force of the heart's contractions. This reduction in cardiac output can quickly progress to asystolia, which is the complete cessation of electrical and mechanical heart activity. Such profound toxic effects make any ingestion of the plant a critical medical emergency.
