Roselle (Hibiscus sabdariffa L.) is a valuable medicinal plant widely used in the pharmaceutical, food, and industrial products. In order to investigate the effects of vermicompost and seaweed foliar application on quantitative and qualitative traits of roselle, this research was carried out in Islamic Azad University, Isfahan Branch in spring, summer and autumn of 2016. The experiment was conducted as factorial in the form of a randomized complete block design with three replications. Vermicompost treatments were applied on four levels: zero (control), 5, 10 and 15 ton/ha, and seaweed spraying at three levels: 0 (control), 1 and 1.5g/L at intervals of one month. At the end of experiment, plant height, number of flowers, fresh and dry weights of the plant, fresh and dry weights of calyx, chlorophyll a, b and total, anthocyanin content, vitamin C, flavonoids and titratable acidityof calyx were measured. The results indicated that the use of seaweed and vermicompost improved the quantitative and qualitative characteristics of roselle. The highest plant height, number of flowers per plant, fresh and dry weights of plant and calyx, chlorophyll a, b and total, anthocyanin content, titratable acid, and vitamin C in calyx, were measured in vermicompost 15 ton/ha. Also the highest amount of chlorophyll a, anthocyanin, flavonoids, titratable acid, and vitamin C of calyx, number of flowers per plant and fresh weight of plant were measured in 1.5 g/l seaweed. The highest amount of vitamin C (68.74 mg/100g), titratable acid (4.97%), anthocyanin (1.400mg/g) in calyx, number of flowers per plant (73.33) and plant fresh weight (828.33 g) were observed in vermicompost 15 ton /ha with the foliar application of seaweed 1.5 g/l.

The present study investigates the anti-diabetic properties of dried latex of Calotropis procera (Willd.) R. Br.with vitamin C in diabetic rats. Thirty adult male Wistar rats were randomly and equally divided into six groups as follow: first group) control, second group) diabetes was induced by a single dose of streptozotocin (50 mg/kg b.w by IP) , third group) diabetic rats were treated by 200 mg dried latex per kilogram of body weight, fourth group) the diabetic rats were treated by combined treatments of dried latex (200mg/kg) and vitamin C (100mg/kg) by gavage, fifth group) animals in this group were treated by (200mg/kg) dried latex daily and the sixth group) rats were treated by vitamin C (100mg/kg). After 15 days, the biochemical factors of blood sugar, triglyceride, total cholesterol, and glycated hemoglobin (HbAlc) were evaluated. Results showed that the amount of biochemical factors was increased significantly in the diabetic group.Dried latex and also the combined treatment of dried latex and vitamin C reduced the elevated levels of abovementioned biochemical factors. Moreover, the aqueous extract of dried latex compared to the group four, was more effective. In conclusion, the dried latex of Calotropis procera has anti-diabetic activity.

In order to evaluate the effects of different fertilizer systems and irrigation water on some phytochemical characteristics of Roselle (Hibiscus sabdariffa L.), a field experiment was conducted at the University of Jiroft during 2013 and 2014. The study was conducted as split plot based on a randomized complete blocks design with three replications. Three irrigation levels (100%, 80% and 60% of crop water requirement) were assigned as main plot factor. Four fertilizers including mycorrhiza, vermicompost, cow manure, and chemical fertilizer (NPK) were allocated as sub plot factor. The results indicated that fertilizer treatments and different irrigation water levels had significant effect on total phenol, anthocyanin, acidity of calyx, seed protein and seed oil. The highest and lowest anthocyanin (3.05 and 2.78 ml.gr-1), total phenol (12.52 and 12.90 ml.gr-1) and acidity of calyx (0.81 and 0.87 gr.100 gr dry weight) belonged to vermicompost and cow manure. Also, 60% and 100% crop water requirement produced the highest and lowest anthocyanin (3 and 2.19 ml.gr-1), total phenol (13.04 and 10.81 ml.gr-1) and seed protein (20.90% and 20.01%). Furthermore, the interaction effect of fertilizer systems and irrigation levels had a significant effect on anthocyanin content. The interaction effect of irrigation levels and year had a significant effect on oil seed. Vitamin C was not affected by experimental treatments.

Jujube (Ziziphus jujuba Mill.) is one of the invaluable medicinal plants, widely used in the pharmaceutical industry due to its vitamins, mucilage, antioxidants, alkaloids and phenolic compounds. Calcium, involved in determining the fruit quality, is one of the most important minerals and its role in the improvement of secondary metabolites in plants has been proved. Nevertheless, little information is available regarding the foliar application of this element on jujube plant. Hence, the current research was aimed to investigate the effects of foliar application of calcium nitrate or calcium chloride on antioxidant properties and quality attributes of jujube fruit. The study was carried out in a randomized complete block design. Treatments were included control (distilled water), calcium chloride (0.5 and 1%) and calcium nitrate (0.5 and 1%). The Foliar application was done in two stages; in fruit cell division stage (20 days after full bloom) and in fruit cell growth stage (40 days after full bloom). The results showed that foliar application of calcium nitrate (0.5%) significantly increased the titratable acidity of the fruit. Calcium chloride treatment (0.5%) also increased fruit anthocyanin content compared to the control. The highest antioxidant properties, vitamin C, and calcium content were obtained in calcium chloride (1%) treatment. The maximum values of chlorophyll a, b and total were observed in the leaves treated with calcium nitrate at a concentration of 1%. In general, the results showed that foliar application of calcium salts improved the quality and antioxidant properties of jujube fruits compared to the control.

Rhabdomyolysis is an injury of skeletal muscle and it causes leakage of cellular contents including myoglobine. Myoglobinuria may produce acute renal failure due to the oxidative reactions. In the present study, the effect of silymarin and vitamin C (as natural antioxidant) was compared on myoglobinuric renal toxicity in rats after glycerol injection. This study was carried in 7groups of rats: Group 1: control, group 2: glycerol, group 3: glycerol + silymarin by injection, group 4: glycerol + silymarin and vitamin C by injection, group5: glycerol + vitamin C by injection, group 6: glycerol + silymarin by orally and group7: glycerol + vitamin C by orally. Serum of rats was isolated 24 hours after glycerol injection. Serum concentrations of BUN, creatinine, sodium and potassium were determined as renal function indexes. Also myoglobine, gama glutamyl transferase and alkaline phosphatase levels were measured by kit. According to the results, the glycerol caused muscular injury and significantly elevated myoglobine. This elevation was controlled by injection of vitamin C. The changes of other serum factors were better controlled by injection of vitamin C than that of silymarin. Myoglobinuric renal failure was modulated by oxidative stress as vitamin C showed a protective effect. However, Silymarin did not have any effects on muscular injury and renal toxicity while it was effective when co-administrated with vitamin C.
