In Vivo Effects

The genus Meloidogyne includes species of the most common nematodes to affect crops around the world. The species M. enterolobii is notable for affecting and causing serious losses in the production of guava trees and various other economically important crops in Brazil. The aim of this study was to evaluate the susceptibility of 10 plant species to parasitism by M. enterolobii, and the in vitro and in vivo effects of their leaf extracts on the pathogen. Initially seedlings of Solenostemon scutellarioides, Dieffenbachia amoena, Spigelia anthelmia, Plumbago scandens, Ricinus communis, Chenopodium ambrosioides, Azadirachta indica, Morinda citrifolia, Jatropha curcas and Datura stramonium were inoculated with 5,000 eggs of M. enterolobii to evaluate their susceptibility to nematode infection. For the test in vitro, a 5% concentration of the leaf extracts were added to Petri dishes, and 50 J2 of M. enterolobii were placed in each dish. After 48 hours incubation, the juveniles were evaluated for motility and mortality in the extracts. For the test in vivo, leaf extracts were used at the same concentration, however with only the seven most-promising in vitro species. This assay included the following sequence: inoculation of 5,000 eggs in autoclaved and moist soil contained in 1L pots; application of 30 ml of extract to the soil after 24 hours; transplanting of ‘Santa Clara’ tomato seedlings the following day; and reapplying the extract after 7 and 14 days. The results were evaluated 45 days after nematode inoculation. It was seen that the species D. amoena, R. communis, A. indica, M. citrifolia, J. curcas and D. stramonium displayed highly resistant behaviour; S. anthelmia, P. scandens and C. ambrosioides were very resistant, whereas S. scutelarioides was susceptible to the nematode. With the in vitro test, extracts from seven of the 10 species caused 70.4% to 97.4% J2 mortality. Applying the best leaf extracts to the soil was efficient in reducing M. enterolobii infestation in roots of the tomato.

Glycogen Stores

The effect of a carbohydrate-arginine supplement on postexercise muscle glycogen storage was investigated. Twelve well-trained cyclists rode for 2 hr on two separate occasions to deplete theirmuscle glycogen stores. At 0, l, 2, and 3 hr after each exercise bout, the subjects ingested either a carbohydrate (CHO) supplement (1 g carbohydrate/kg body weight) or a carbohydrate-arginine (CHO/AA) supplement (1 g carbohydrate/kg body mass and 0.08 g arginine-hydrochloride/kg body weight). No difference in rate of glycogen storage was found between the CHO/AA and CHO treatments, although significance was approached. There were also no differences in plasma glucose, insulin, or blood lactate responses between treatments. Postexercise carbohydrate oxidation during the CHO/AA treatment was significantly reduced compared to the CHO treatment. These results suggest that the addition of arginine to a CHO supplement reduces the rate of CHO oxidation postexercise and therefore may increase the availability of glucose for muscle glycogen storage during recovery.

<p><strong>Objective: </strong>To determine the <em>in vitro</em> anti-obesity effects of <em>Morinda citrifolia</em> leaf extract and herbal formulas used for weight loss in Thailand on lipid accumulation in 3T3-L1 adipocytes.</p><p><strong>Methods: </strong>Differentiated 3T3-L1 adipocytes were treated with 0.1, 0.5 and 1 mg/ml <em>M. citrifolia</em> leaf extract, three herbal formulas (JL-RU, JL-TH, CD-H) and 1, 5 and 10 mg/ml rutin, gallic acid and caffeine. Lipid accumulation determined by measuring Oil Red O staining and triglyceride content measured by a colorimetric method in adipocytes were assayed compared to the control. The effect of test samples on the viability of preadipocytes and differentiated adipocytes were investigated.<strong></strong></p><p><strong>Results: </strong>Differentiated adipocytes treated with 1 mg/ml <em>M. citrifolia</em> extract moderately inhibited fat accumulation (45.12%) and highly reduced triglyceride content (85.09%). Among the three herbal formulas, JL-TH considerably inhibited fat accumulation (109.17%, 1 mg/ml) and decreased triglyceride content (95.00%, 1 mg/ml) in adipocytes; this was higher than that for CD-H and JL-RU, respectively. The viability of preadipocytes treated with CD-H at 1 mg/ml was slightly decreased while those treated with JL-TH at 0.05-1 mg/ml showed moderately decreased viability in a dose-response manner. For differentiated adipocytes, CD-H at 0.5-1 mg/ml moderately decreased cell viability while JL-TH at 0.05-1 mg/ml caused moderate to high reduction of cell viability in a dose-response relationship.</p><p><strong>Conclusion: </strong><em>M. citrifolia</em> extract and three herbal formulas had anti-obesity effects in 3T3-L1 adipocytes, as indicated by a significant reduction in lipid accumulation, triglyceride content, and cell viability. These findings suggest a potential therapeutic approach for the prevention and treatment of obesity.</p>

<p>ITS Surabaya campus has a biodiversity potential, especially plants that can be utilized. Different types of plants have been known as a potential insecticide because they contain bioactive compounds, such as essential oils, saponins, tannins, alkaloids, phenolics, flavonoids, alkenes and these terpenoids. This research was a descriptive experimental, which aimed to explore the vegetation potential as plant-based insecticide or bio-insecticide. Tracking method to obtain plant leaves samples in ITS campus was used in this study. Leaf extracts were obtained using methanol solvents after the freeze-drying method that will change leaf into powder form. The extracts were then stored in the refrigerator and ready to be applied. Leaf dipping method was used as biological test. The test conducted on Spodoptera litura larvae that obtained from Balittas Malang. Larvae rearing trials were carried out in the Laboratory of Botany, Department of Biology ITS. The larvae examined were the third instar fed on fodder greens of leaf mustard. Toxicity effects of extract were observed from mortality of Spodoptera litura during 5 days. Ten plants species with bio-insecticide potential in this study were Ageratum conyzoides L., Crynum asiaticum L., Calotropis gigantea R., Eugenia cumini Merr., Eichornia crassipes, Crescentia cujete L., Nothopanax scutellarium Merr., Morinda citrifolia L., Azadirachta indica, and Lantana camara L. <br /><strong></strong></p><p><strong>Keywords</strong> : Bio-insecticide, potential plants, Spodoptera litura</p>

Anthracnose is a plant disease that can infect a variety of plants worldwide. Fungal pathogen groups are the cause of anthracnose, one of which is Colletotrichum acutatum. Morinda citrifolia is famous for having antimicrobial activity. This study aims to determine the antifungal activity of M. citrifolia leaves extract against the growth of the fungus C. acutatum. The extract solvent used was 96% ethanol. The experiment consisted of five treatments (0%, 20%, 40%, 60% and propineb 0.1% as positive control). The method used in this study was the poisoned food technique. In this technique, C. acutatum was grown on PDA media mixed with M. citrifolia leaves extract. Antifungal activity was observed based on reduced mycelium growth compared to control. Observations were made every day by measuring the diameter of the fungus mycelium for eleven days. The analysis showed that 60% M. citrifolia leaves extract effectively inhibited the growth of the mycelium C. acutatum on the eleventh day of observation.

Fusarium oxysporum is an important disease that causes wilt disease in plants. Fungal pathogen control using synthetic fungicides can cause negative impacts on the environment. Morinda citrifolia is one of the herbs that is known for many benefits. M. citrifolia leaf contains anthraquinone which have potential as antifungal agents. In this study, in vitro anti-fungal assay was conducted against F. oxysporum to analyze the antifungal activity of ethanol extract of M. citrifolia leaves. In vitro evaluation was carried out using poisoned food technique at four different concentrations i.e., 20%, 40%, 60% and 80%. The results showed concentration 60% gave the highest inhibitory effect (21,82%) on F. oxysporum mycelium growth.
