| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

Reproductive activities of female albino rats treated with quassin, a bioactive triterpenoid from stem bark extract of Quassia amara.[Pubmed:22314945]
Niger J Physiol Sci. 2010 Nov 24;25(2):95-102.
To evaluate the effect of Quassin on female reproductive functions, 42 albino rats (35 females and 7 males) were used. The female albino rats were divided into seven groups of five rats each. Group I served as the control group and received distilled water while Groups II, III and IV rats were treatedorally with 0.1mg/kg, 1.0 mg/kg and 2.0 mg/kg body weight of Quassin for 60 days respectively. Groups V, VI and VII rats were also treated orally with 0.1 mg/kg, 1.0mg/kg and 2.0 mg/kg body weight of Quassin for 60 days but were left untreated for another 30 days, to serve as the recovery groups. At the end of each experimental period, blood samples were collected from each rat. Fertility study was done by cohabiting one untreated male with the five female rats in each group for 10 days. Quassin did not adversely affect the weight of the kidney, heart, liver and the body of the rats. However there was a significant decrease in the weight of the ovary and uterus in all the groups relative to the control. There was also a significant decrease in serum estrogen levels in Quassin treated rats. The Quassin treated rats had a significantly decreased mean litter number and weight. Histological studies show a disorganization and degeneration in the ovary while the uterus showed signs of vacuolation and disorganization. However, these effects were ameliorated after Quassin was withdrawn from the rats. The results suggest that Quassin has female anti-fertility properties, possibly acting via inhibition of estrogen secretion.
Effects of bioactive principles from stem bark extract of Quassia amara, Quassin and 2-methoxycanthine-6-one, on haematological parameters in albino rats.[Pubmed:22314946]
Niger J Physiol Sci. 2010 Nov 28;25(2):103-6.
The effect of Quassia amara extract and two isolated compounds from the extract, Quassin and 2-methoxycathine-6-one on haematological parameters was studied in rats. All doses of the extract and those of the Quassin significantly increased red blood cell count, packed cell volume and haemoglobin concentration.However, there was no significant increase in the total white blood cell count.There was also no significant change in all parameters studied with 2-methoxycanthine-6-one. The results suggest that quassia extract possesses antianaemic property.
Plasmodium falciparum: in vitro interaction of quassin and neo-quassin with artesunate, a hemisuccinate derivative of artemisinin.[Pubmed:20036657]
Exp Parasitol. 2010 Apr;124(4):421-7.
Quassia amara L. (Family Simaroubaceae) is known to have several medicinal properties including the activity against malaria. An HPLC method was employed for purification of the biologically active Quassinoids; Quassin (Q) and neo-Quassin (NQ), further characterized by MALDI-TOF analyses. Purified Q, NQ and the crude bark extract (S1) along with artesunate (AS) were studied for their in vitro anti-plasmodial activity. The in vivo toxicity studies at intraperitoneal doses with higher concentrations of the crude bark extract (S1) in Balb/C mice ruled out the apprehension of toxicity. Interaction studies between the test compounds among themselves (Q+NQ) and individually with artesunate (AS+Q, AS+NQ), were carried out in vitro at four ratios (1:5, 1:2, 2:1 and 5:1) on chloroquine sensitive (MRC-pf-20) and resistant (MRC-pf-303) strains of Plasmodium falciparum. The crude bark extracts of Q. amara exhibited higher P. falciparum inhibitory activity (IC(50)=0.0025 microg/ml) as compared to that of the isolated compounds, Quassin (IC(50)=0.06 microg/ml, 0.15 microM), neo-Quassin (IC(50)=0.04 microg/ml, 0.1 microM) and also to the positive control, artesunate (IC(50)=0.02 microg/ml, 0.05 microM). The in vitro drug interaction study revealed the compounds, Quassin and neo-Quassin to be additive to each other. At lower ratios, artesunate was found to be a potential combination partner with both the compounds. It was interesting to note that none of the combinations exhibited antagonistic interactions. This phenomenon offers the opportunity for further exploration of novel therapeutic concentrations and combinations.
