Pakistan Journal of Nutrition , 2011,
Abstract: The present study aimed to investigate whether or not maternal consumption of aqueous extract of Hibiscus sabdariffa (HS) during lactation has any effect on the body weight and body mass index at onset of puberty in the female offspring. Eighteen in-bred virgin female Sprague-Dawley rats aged between 10-12 weeks and weighing 1255.5g (meanSEM) with two consecutive regular 4-day estrus cycle were used for this study. On the day of delivery, the dams and their pups were randomly assigned to one of three groups of 6 rats/group. One group had tap water (control), another had 0.6g-HSextract/100ml in their drinking water while the third group had 1.8g-HSextract/100ml in their drinking throughout lactation. Results showed that maternal consumption of aqueous extract of HS during lactation at the doses tested, delayed onset of puberty and elevated body weight and body mass index at onset of puberty in female offspring.

Abstract: The present study was designed to investigate whether or not maternal consumption of aqueous extract of Hibiscus sabdariffa (HS) during pregnancy has any effect on the growth and onset of puberty in the female offspring. Eighteen in-bred virgin female Sprague-Dawley rats aged between 10-12 weeks and weighing 125±5.5g (mean±SEM) with two consecutive regular 4-day estrus cycle were randomly assigned to one of three groups of 6 rats/group. One group had tap water (control); another had 1.5g-extract/kg while the third group had 3.0g-extract/kg in their drinking water throughout pregnancy. Results showed that HS consumption during pregnancy significantly decreased maternal fluid and food intake, increased postnatal weight gain and delays the onset of puberty in the female offspring.

Abstract: The present study was designed to investigate whether maternal consumption of aqueous extract of Hibiscus sabdariffa (HS) during lactation will affect the postnatal growth and onset of puberty in the female offspring. Eighteen in-bred virgin female Sprague-Dawley rats aged between 10-12 weeks and weighing 125 ± 5.5g (mean ± SEM) with two consecutive regular 4-day estrus cycles were randomly assigned to one of three groups of 6rats/group. One group had tap water (Control); another had 0.6g/100ml while the third group had 1.8g/100ml in their drinking water throughout lactation (21 days). Results showed that HS consumption during lactation significantly (P<0.05) decreased maternal fluid and food intake, increased postnatal weight gain and delays the onset of puberty in the female offspring.

Nigerian Journal of Physiological Sciences , 2008,
Abstract: Consumption of extracts of Hibiscus sabdariffa (family: malvaceae) during pregnancy has been shown to cause maternal malnutrition which has been linked to various adverse conditions like increased postnatal weight gain, delayed puberty onset and elevated body weight and body mass index at onset of puberty in the female offspring. The present study was designed to investigate the possible mechanism underlying this. Eighteen in-bred pregnant Sprague-Dawley rats were on day 1 of pregnancy, randomly divided into three groups of six animals each. Group A (control) was given tap water to drink. Group B was given 0.6g extract/100ml while Group C was given 1.8g extract/100ml as their drinking solution. All groups received normal rat chow and their drinking solution ad libitum. Fluid and food intake and dam weights were measured daily throughout pregnancy. On gestational day 18, blood sample was withdrawn from each rat for estimation of plasma Na ion and corticosterone levels. On the day of delivery, the solutions of the extracts of Hibiscus sabdariffa were withdrawn and replaced with tap water. After 21 days, the pups were weaned to tap water and food ad libitum. Pups weight and age and body mass index at onset of puberty were measured. The results of the present study showed that the increased postnatal weight gain, delayed puberty onset and elevated body mass index at onset of puberty in the offspring of rats that consumed HS during pregnancy was associated with elevated maternal plasma Na ion and corticosterone levels during pregnancy.

Pakistan Journal of Nutrition , 2011,
Abstract: The present study was designed to investigate the effect of consumption of aqueous extract of Hibiscus sabdariffa (HS) during pregnancy on fluid and food intake, weight gain during pregnancy, length of gestation, litter size and birth weight. Eighteen in-bred virgin female Sprague-Dawley rats aged between 10-12 weeks and weighing 125 5.5g (mean SEM) with two consecutive regular 4-day estrus cycle were used for this study. These rats were randomly assigned to one of three groups on gestational day one. Group A (control) were given tap water to drink throughout pregnancy, while groups B and C were given 0.6g-extract/100ml and 1.8g-extract/100ml respectively to drink throughout pregnancy. All groups had normal rat chow and their respective drinking solution ad libitum. Mean fluid and food intake and total pregnancy weight gain were significantly reduced in the HS group. There was no significant difference in length of gestation among the various groups but there was a significant reduction in litter size and a significant increase in litter birth weight in HS groups (B and C) compared with control group (A). There were no apparent malformations at birth.

African Journal of Biomedical Research , 2007,
Abstract: The effect of maternal consumption of aqueous extract of Hibiscus Sabdariffa during pregnancy on pregnancy weight gain and postpartum weight loss was investigated in Sprague-Dawley rats. Fifteen in-bred pregnant female Spague-Dawley rats were randomly assigned to groups A, B and C on day one of pregnancy. Group C rats had tap water while groups A and B rats had 0.6g HS extract and 1.8g HS extract respectively in 100ml tap water to drink throughout pregnancy and through 34 days postpartum. All the rats in all the groups were fed normal rat chow ad libitum. Dam weights were measured daily throughout pregnancy and at delivery, 10, 14, 20 and 34 days postpartum. Results of the present study show a significant concentration dependent decrease in both pregnancy weight gain and postpartum weight loss at the doses tested. (Afr. J. Biomed. Res. 10: 257 – 261)

Abstract: The present study was designed to investigate whether or not maternal consumption of aqueous extract of Hibiscus sabdariffa (HS) during pregnancy has any effect on body weight, body mass index (BMI) and weights of some selected visceral organs at onset of puberty in the female offspring. Eighteen in-bred virgin female Sprague-Dawley rats aged between 10-12 weeks and weighing 125 ± 5.5g (mean ± SEM) with two consecutive regular 4-day estrus cycle were randomly assigned to one of three groups of 6rats/group. One group had tap water (control); another had 1.5g-extract/kg while the third group had 3.0g-extract/kg in their drinking water throughout pregnancy. Maternal fluid and food intake were recorded throughout pregnancy and offspring weights were recorded at birth, weaning and weekly thereafter until onset of puberty. Results showed that HS consumption during pregnancy significantly decreased maternal fluid and food intake; increased body weight, BMI and the weights of the kidney, liver, heart and spleen; and delays the onset of puberty in the female offspring.

Journal of Applied Phytotechnology in Environmental Sanitation , 2012,
Abstract: The purpose of this work is to determine the basic antiseptic activity of two Hibiscus species in comparison with the already established antibacterial activity of Moringa oleifera seeds. Crude extracts were obtained from Moringa oleifera, Hibiscus esculentus and Hibiscus sabdariffa seeds using water but essential oils were extracted only from Moringa oleifera using hexane. All the extracts showed varying degrees of inhibition on the tested organisms. On analysing for any significant difference between the treatments, no statistically significant differences could be established between treatments of Hibiscus sabdariffa and Hibiscus esculentus as well as Moringa oleifera and Hibiscus esculentus extracts. The study shows that the antimicrobial properties of Hibiscus esculentus seeds compare favourably with those of already popular Moringa oleifera seeds. The use of the Hibiscus esculentus and Hibiscus sabdariffa seeds in drinking water treatment should be explored.

Abstract: dietary fiber and antioxidants are food constituents and functional ingredients that are generally addressed separately. nowadays there is scientific evidence that primary characteristics of df assigned to non starch polysaccharides and lignin (resistance to digestion and absorption in the small intestine and fermentation in the large intestine) can be extended to other indigestible food constituents that are resistant to digestion and absorption in the human small intestine with complete or partial fermentation in the large intestine. the antioxidant dietary fiber concept was defined as a dietary fiber concentrate containing significant amounts of natural antioxidants associated with non digestible compounds. hibiscus sabdariffa l flower shows in its composition an important percentage of dietary fiber and high antioxidant capacity. the infusion obtained by decoction of flowers, had been extensibility studied due to the healthy properties. in this work the principal nutritional aspects from hibiscus sabdariffa l and its use as a possible antioxidant dietary fiber source had been considered.

Abstract: Transgenic Hibiscus sabdariffa plants have been produced by a tissue culture independent method using Agrobacterium tumefasciens transformation procedure. Embryo axes of mature seeds with one cotyledon excised were infected by immersion in a suspension of Agrobacterium LBA 4404 strain culture that carries pBal plasmid with β-glucuronidase p35SGUSINT and plant selectable marker Neomycin Phospho-Transferase gene (nptII). Following a 24 h co-cultivation with Agrobacterium strain and decontamination with cefotaxime, embryos were grown on soil rite containing MS medium added with a killer concentration of kanamycin (100 μg/ml) during 4 weeks at room conditions and thereafter transferred to greenhouse. 54.3% of the seedlings grew well on the selective medium; 68% of the explants excised from putative transformed plants were found to be GUS positive. After 60 days evaluation point, the assessment of the transformation by PCR revealed that H. sabdariffa line tested, carried the nptII gene. Key Words: Hibiscus sabdariffa; genetic transformation.
