生物堿
荷葉堿是從睡蓮科植物蓮的干燥葉中提取的一種阿樸啡型生物堿,為荷葉中的主要降脂活性成分,以曬干粉碎的荷葉為原料,采用纖維素酶預處理、稀鹽酸浸提、超聲波輔助提取、氯仿萃取一系列方法提取而成。
中醫(yī)學認為,荷葉性味苦澀,平,歸肝、脾、胃、心經。有清暑利濕、升發(fā)清陽、涼血止血等功效。荷葉的主要化學成分有荷葉堿、檸檬酸、草酸等,起主要減肥作用的是荷葉堿,藥理研究表明,荷葉具有利尿通便、通腸毒、降脂除油、清暑解熱等作用,能明顯降低血清中甘油三醇和膽固醇含量,具有調節(jié)血脂的保健作用。采用荷葉減肥不需要刻意節(jié)食,對人體無任何副作用。

體外研究

Nuciferine is a partial agonist at DD 2 receptor with an activity (E max =67% of dopamine) similar to aripiprazole (E max =50% of dopamine). In line with its partial agonist activity, Nuciferine inhibited dopamine-induced activation of G i with a potency similar to clozapine (Nuciferine K B =62 nM; Clozapine K B =20 nM) as determined via Schild regression analysis. The natural product Nuciferine acts as an effective inhibitor of adult worm motility. Nuciferine is effective at inhibiting both basal and 5-HT evoked motility of adult schistosomes. Nuciferine inhibits Sm.5HTR L and schistosomule with 0.24±0.04 and 0.62±0.22 μM, respectively.

體內研究

In rodent models relevant to antipsychotic drug action, Nuciferine blocks head-twitch responses and discriminative stimulus effects of a 5-HT 2A agonist, substituted for clozapine discriminative stimulus, enhanced amphetamine induced locomotor activity, inhibited phencyclidine (PCP)-induced locomotor activity, and rescued PCP-induced disruption of prepulse inhibition without induction of catalepsy. In the presence of 1 or 3 mg/kg Nuciferine, cumulative PCP doses produce similar substitution to PCP alone. In the clozapine-trained animals, a dose-dependent substitution for 1.25 mg/kg clozapine is seen at 10 mg/kg Nuciferine (80.63% drug lever responding), with an ED 50 value of 5.42 mg/kg (95% CI 3.09-9.48 mg/kg) while the lower doses tested (0.1 mg/kg-3 mg/kg) fails to produce substitution for clozapine’s discriminative cue. In addition to a high percentage of responding on the clozapine-appropriate lever, 10 mg/kg Nuciferine also produces significant rate suppression as compared to vehicle control points (p<0.001).
