In this study toxicity of Euphorbia royleana latex and stem bark extract was evaluated in a static bioassay test for the fry and fingerlings of freshwater fish Channa punctatus. For fry the LC50 values for Euphorbia royleana latex were 12.66, 6.27, 4.04 and 3.05 mg/L whereas for stem bark extract the LC50 values were 113.77, 89.16, 71.99 and 56.59 mg/L for 24, 48, 72 and 96 h, respectively. It seems that toxicity of latex was more pronounced as compared to stem bark extract. The LC50 values for latex for fingerlings were 22.58, 18.14, 14.99 and 12.34 mg/L whereas for stem bark extract the LC50 values were 614.35, 585.06, 535.93 and 475.37 mg/L for 24, 48, 72 and 96 h, respectively. The activities of the latex and stem bark extract were time- and dose-dependant. The present study clearly indicates that Euphorbia royleana extracts should be applied with great precautions nearby the aquatic reservoirs as it is toxic to growing stages of the fish.

Diethyl Ether Extract

The piscicidal activity of the diethyl ether extract of Euphorbia royleana stem bark has been well established, but its ultimate mode of action and short, as well as long-term, biochemical effects are not yet known. Exposure of fish for either 24 or 96 hours to sub-lethal doses (40% and 80% of LC50) of the diethyl ether extract of the stem bark, significantly (P<0.05) altered total protein, total free amino acids, nucleic acids, glycogen, pyruvate, and lactate levels, as well as protease, aminotransferase, phosphatases and cytochrome oxidase enzyme activity in liver and muscle tissue of the freshwater fish Channa punctatus. These alterations were significantly (P<0.05) time and dose dependent. Thus, the diethyl ether extract of E. royleana stem bark shifts the aerobic pathway of fish respiration towards the anaerobic segment and also suppresses ATP production. This toxic effect was reversible, and seven days after withdrawal, all biochemical parameters were back to normal. These results support the view that the diethyl ether extract of E. royleana stem bark can be used for controlling unwanted populations of the predatory fish C. punctatus from aquaculture ponds.

This study was designed to determine the effect of Carica papaya L. stem bark extracts on cholesterol concentration in rats induced with glibenclamide. A completely randomized design was used for the experiment which consisted of 6 treatment groups, each group consisted of four rats, as follows:1) KN (negative control, non-diabetic rats); KP, diabetic rats given glibenclamide 10 mg/kg body weight; EP 1, diabetic rats given 0 mg/kg body weight/day extract; EP2, diabetic rats given 100 mg/kg body weight/day extract; and EP3, diabetic rats given 200 mg/kg body weight/day extract, EP4, diabetic rats given 300 mg/kg body weight/day extract for 28 day. The results showed that C. papaya L. stem bark extract decreased (P<0.05) cholesterol levels in diabetic rats. It was concluded that C. papaya L. stem bark extract had potential as anti-hypercholesterolemic in diabetic rats.
