I. Effect of different parts and influence of the solvent on hypoglycaemic activity. SOURCE J Ethnopharmacol; VOL 40, ISS 3, 1993, P163-6 ABSTRACT Artemisia herba alba is widely used in Iraqi folk medicine for the treatment of diabetes mellitus. Oral administration of 0.39 g/kg body weight of the aqueous extract of the leaves or barks produced a significant reduction in blood glucose level, while the aqueous extract of roots and the methanolic extract of the aerial parts of the plant produce almost no reduction in blood glucose level. The extract of the aerial parts of the plant seem to have minimal adverse effect and high LD50 value. 6 AUTHOR Winkelman M TITLE Ethnobotanical treatments of diabetes in Baja California Norte. SOURCE Med Anthropol; VOL 11, ISS 3, 1989, P255-68 (REF: 41) ABSTRACT This paper provides a brief review of the current biomedical knowledge on some of the medicinal plants used in the treatment of diabetes in Baja California Norte. In general there is very little biochemical knowledge of the specific modes of action in the treatment of diabetes, but most of the plants have been found to contain substances (e.g., glucosides, alkaloids) frequently implicated as having anti-diabetic effects. Furthermore, clinical studies with animals indicate that most of these plants do have hypoglycemic properties. This paper calls attention to the need for further biochemical investigations into the plant constituents and invites collaboration in the development of clinical field studies to assess the efficacy of herbalists' use of medicinal plants in the treatment of diabetes in Baja California Norte or other U.S.-Mexico border areas. Such research can make an important contribution to the World Health Organization's plan of "Health for All by the Year 2000" through establishing a scientific basis for traditional medicine. 7 AUTHOR Twaij HA AUTHOR Al-Badr AA TITLE Hypoglycemic activity of Artemisia herba alba. SOURCE J Ethnopharmacol; VOL 24, ISS 2-3, 1988, P123-6 ABSTRACT Artemisia herba alba has been widely used in Iraqi folk medicine for the treatment of diabetes mellitus. Oral administration of an aqueous extract (0.39 g/kg) of the aerial parts of this plant to normoglycemic and to alloxan-diabetic rabbits produced significant hypoglycemic activity, which was consistent and time-dependent. 2 AUTHOR Mosihuzzaman M AUTHOR Nahar N AUTHOR Ali L AUTHOR Rokeya B AUTHOR Khan AK AUTHOR Nur-E-Alam M AUTHOR Nandi RP TITLE Hypoglycemic effects of three plants from eastern Himalayan belt. SOURCE Diabetes Res; VOL 26, ISS 3, 1994, P127-38 ABSTRACT Rhizome of Costus speciosus, tuber of Nephrolepsis tuberosa, and bulb of Stephania hernandifolia, used by the local people and traditional healers in the Eastern Himalayan belt, were studied for their effects on serum glucose levels in nondiabetic and diabetic rat models at different prandial states. The results showed that in nondiabetic rat C speciosus and N tuberosa had no significant effect in the fasting or postprandial state when freeze-dried juices were fed simultaneously with glucose. However, when fed 30 min before the glucose load both C speciosus (p < 0.05) and N tuberosa (p < 0.003) showed hypoglycemic effect. To the contrary, S hernandifolia increased the serum glucose levels of nondiabetic rats in all the series of experiments (p < 0.05 or p < 0.01). In NIDDM model rats N tuberosa opposed the rise in serum glucose level when it was fed 30 min before the glucose load (p < 0.02), whereas S hernandifolia had a tendency to raise the serum glucose level. In IDDM model rats, none of these three freeze-dried juice showed any effect in the fasting state. However, C speciosus showed significant hypoglycemic effect (p < 0.002) when the juice was fed with simultaneous glucose load. In marked contrast to the findings with nondiabetic and NIDDM model rats S hernandifolia showed significant hypoglycemic effect (p < 0.05-0.006) in both the stages (fed simultaneously with, and 30 min before the glucose load) of prandial states of the IDDM model rats. The results indicated that these three plants have interesting possibilities as a source of oral hypoglycemic agents. 3 AUTHOR Jahodar L TITLE [Plants with hypoglycemic effects] SOURCE Cesk Farm; VOL 42, ISS 6, 1993, P251-9 ABSTRACT Diabetes mellitus is a metabolic disorder which has affected several millions of population all over the world. It is characterized by an excess of sugar in the blood and urine, hunger, thirst and gradual loss of weight. Insulin is a hormone which regulates the carbohydrate and triacylglyceride metabolism through its action at several sites and facilitates the entry of glucose accumulation in the blood. Insulin also stimulates the synthesis of glucokinase and moderates the degree of gluconeogenesis. In the diabetic patient, there is an aberration in the functioning of insulin. Prior to the 1950s, control of diabetes was based entirely on insulin therapy. Unfortunately, some patients developed complications and thus need for some other therapy was realized. Presently control of NIDDM relies on compounds from two classes--sulphonylureas and biguanides. Although these drugs are widely accepted as being efficacious in treating some diabetics, they are ineffective in many others. Consequently, testing of many chemicals and plant extracts has continued. The object of the present paper is to bring up-to-date information on the hypoglycemic activity of plants, above all the plants occurring in our country, and those who se hypoglycemic activity has been scientifically documented in a more detailed way. Recent theories on the mechanism of action of these plants are also discussed. 4 AUTHOR Ali L AUTHOR Khan AK AUTHOR Mamun MI AUTHOR Mosihuzzaman M AUTHOR Nahar N AUTHOR Nur-e-Alam M AUTHOR Rokeya B TITLE Studies on hypoglycemic effects of fruit pulp, seed, and whole plant of Momordica charantia on normal and diabetic model rats. SOURCE Planta Med; VOL 59, ISS 5, 1993, P408-12 ABSTRACT Extracts of Momordica charantia fruit pulp, seed, and whole plant were tested for their hypoglycemic effects on normal and diabetic rat models. The results show that during the oral glucose tolerance test the peak blood glucose values in rats are obtained much earlier (15-45 min) than in human subjects (around 60 min). Pulp juice of M. charantia lowered fasting blood glucose levels in normal rats (p < 0.05 at 120 min); the effect was more pronounced with the saponin-free methanol extract of the pulp juice (p < 0.05 at 60 min and p < 0.01 at 120 min). The pulp juice also had a significant hypoglycemic effect in the glucose-fed normal rats when the extract was fed 45 minutes before the oral glucose load [percentage increments over basal value (M +/- SE): 85 +/- 10 in the control group vs. 54 +/- 7 in the pulp juice group, p < 0.01]. In the IDDM model rats the pulp juice had no significant effect on blood glucose levels either in fasting or postprandial states. In the NIDDM model rats the saponin-free methanol extract of juice produced a significant hypoglycemic effect both in fasting (p < 0.05 at 120 min) and in postprandial states (sum of percentage increments over basal value: 140 +/- 26 in the control vs. 71 +/- 7 in the pulp juice group, p < 0.05). Methanol extracts of seed and of whole plant, and saponin-free methanol extract of whole plant produced no hypoglycemic effects in normal or IDDM model rats either in fasting or in postprandial states.(ABSTRACT TRUNCATED AT 250 WORDS) 6 AUTHOR Roman Ramos R AUTHOR Lara Lemus A AUTHOR Alarcon Aguilar F AUTHOR Flores Saenz JL TITLE Hypoglycemic activity of some antidiabetic plants. SOURCE Arch Med Res; VOL 23, ISS 3, 1992, P105-9 ABSTRACT To assess the hypoglycemic activity mechanism of some plants used empirically by the Mexican population as antidiabetics, traditional preparations of Cucurbita ficifolia, Guaiacum coulteri, Lepechinia caulescens, and Psacalium peltatum, water, tolbutamide, and Regular Insulin were administered to three groups of rabbits each: 1. Healthy rabbits with temporary hyperglycemia induced by the subcutaneous administration of glucose. 2. Rabbits with moderate diabetes (fasting glycemia 150-300 mg/dl), induced with alloxan. 3. Rabbits with severe diabetes (fasting glycemia higher than 400 mg/dl), induced with alloxan. The plant preparations had a hypoglycemic effect similar to tolbutamide in healthy and mild diabetic rabbits and had no effect in severely diabetic rabbits. These results suggest that some pancreatic function or the presence of insulin is required for the hypoglycemic activity of these plants. 7 AUTHOR Roman Ramos R AUTHOR Alarcon-Aguilar F AUTHOR Lara-Lemus A AUTHOR Flores-Saenz JL TITLE Hypoglycemic effect of plants used in Mexico as antidiabetics. SOURCE Arch Med Res; VOL 23, ISS 1, 1992, P59-64 ABSTRACT The objective of this work is to investigate the hypoglycemic effect of 12 "antidiabetic" plants used in Mexico. The studies were performed using 27 healthy rabbits with the gastric administration of water, tolbutamide or decoction of the "antidiabetic" plant before the induction of temporary hyperglycemia by subcutaneous injection of 50% dextrose solution (4 ml/kg of weight) at the beginning of the experiment and after 60 min. Blood glucose was determined every 60 min for a period of 5 h. Tolbutamide and eight of the studied plants decreased significantly the hyperglycemia as compared with control test (water) (p < 0.05). The strongest effect was yielded by Guaiacum coulteri, followed by Marrubium vulgare, Crataegus pubescens, Cynodon dactylon, Calea zacatechichi, Buddleia americana, Bauhinia divaricata and Coix lachryma. The decrease of hyperglycemia caused by Physalis phyladelphyca, Pavonia schiedeana and Eucaliptus globulus was not significant (p > 0.05). Urtica dioica increased glycemia slightly. 9 AUTHOR Atta-Ur-Rahman AUTHOR Zaman K TITLE Medicinal plants with hypoglycemic activity.

SOURCE J Nat Prod; VOL 44, ISS 6, 1981, P648-55 ABSTRACT A hypoglycemic peptide, Polypeptide-p, has been isolated from fruit, seeds, and tissue of Momordica charantia Linn (bitter gourd). Amino acid analysis indicates a minimum molecular weight of approximately 11,000 (166 residues). Polypeptide-p is a very effective hypoglycemic agent when administered subcutaneously to gerbils, langurs, and humans.
