Background: Neuropathic pain is one of the contributors to the global burdens of illness. At present many patients do not achieve satisfactory pain relief even with synthetic pain-killers. Taking this into consideration, it is necessary to search for natural product-derived alternative treatment with confirmed safety and efficacy. Ageratum conyzoides L is a plant often used as analgesic in Indonesia, however, anti-neuropathic pain activity of this plant is still unknown. Objective: To determine the anti-neuropathic pain activity of the essential oil and non-essential oil component (distillation residue) of A. conyzoides L. Methods: We conducted separation of the essential oil component from other secondary metabolites through steam distillation. Both components were tested for anti-neuropathic pain activity using chronic constriction injury animal models with thermal hyperalgesia and allodynia tests. The animals were divided into 7 test groups namely normal, sham, negative, positive (pregabalin at 0.195 mg/20 g BW of mice), essential oil component (100 mg/kg BW), and non-essential oil component (100 mg/kg BW). Naloxone was tested against the most potent anti-neuropathic pain component (essential oil or nonessential oil) to investigate the involvement of opioid receptor. Results: The GC-MS of the essential oil component indicated the presence of 60 compounds. Meanwhile, non-essential oil components contained alkaloid, flavonoid, polyphenol, quinone, steroid, and triterpenoid. This non-essential oil component contained a total flavonoid equivalent to 248.89 ppm quercetin. The anti-neuropathic pain activity test showed significantly higher activity of the essential oil component compared to the non-essential oil component and negative groups (p<0.05). Furthermore, the essential oil component showed equal activity to pregabalin (p>0.05). However, this activity was abolished by naloxone, indicating the involvement of opioid receptor in the action of the essential oil component. Conclusion: The essential oil component of A. conyzoides L is a potential novel substance for use as anti-neuropathic pain.

Natural product-based herbicides could be the effective alternatives to synthetic chemical herbicides for eco-friendly weed management. This research, therefore, was conducted to identify the phytotoxic properties of Parthenium hysterophorus L., Cleome rutidosperma DC. and Borreria alata (Aubl.) DC. with a view to introducing them as a tool for natural herbicide development. The methanol extracts of these plants were examined on the germination and growth of Zea mays L., Oryza sativa L., Abelmoschus esculentus (L.) Moench and Amaranthus gangeticus L., Oryza sativa f. Spontanea Roshev. (Weedy rice), Echinochloa colona (L.) Link., Euphorbia hirta L., and Ageratum conyzoides L. under laboratory and glasshouse conditions. A complete randomized design (CRD) with five replications and randomized complete block design (RCBD) with four replications were laid out for laboratory and glasshouse experiments, respectively. In the laboratory experiment, three plant extracts of 0, 6.25, 12.5, 50, and 100 g L−1 were tested on survival rate, hypocotyl, and radicle length of eight test plant species. No seed germination of A. conzyoides, E. hirta, and A. gangeticus were recorded when P. hysterophorus extract was applied at 50 g L−1. C. rutidosperma had the same effect on those plants at 100 g L−1. In the glasshouse, similar extracts and concentrations used in the laboratory experiments were sprayed on at the 2–3 leaf stage for grasses and 4–6 for the broadleaf species. Tested plants were less sensitive to C. rutidosperma and B. alata compared to P. hysterophorus extract. Among the weeds and crops, A. conyzoides, E. hirta, A. esculentus and A. gangeticus were mostly inhibited by P. hysterophorus extract at 100 g L−1. Based on these results, P. hysterophorus was the most phytotoxic among the tested plant extracts and could be used for developing a new natural herbicide for green agriculture.

The current study was designed to investigate the effect of Parthenium hysterophorus L. methanol extract on Ageratum conyzoides L., Oryza sativa f. spontanea (weedy rice) and Cyperus iria L. in glasshouse condition. Here, Parthenium hysterophorus methanol extract at 20, 40, and 60 g L−1 concentrations was applied on the test species to examine their physiological and biochemical responses at 6, 24, 48 and 72 h after spraying (HAS). The phytotoxicity of P. hysterophorus was strong on A. conyzoides compared to weedy rice and Cyperus iria at different concentrations and exposure times. There was a reduction in photosynthesis rate, stomatal conductance, transpiration, chlorophyll content and carotenoid content when plants were treated with P. hysterophorus extract concentrations. Exposure to P. hysterophorus (60 g L−1) at 24 HAS increased malondialdehyde (MDA) and proline content by 152% and 130%, respectively, in A. conyzoides compared with control. The activities of antioxidant enzymes (superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD)) were also increased in the presence of P. hysterophorus extract. Present findings confirm that the methanol extract of P. hysterophorus can disrupt the physiological and biochemical mechanism of target weeds and could be used as an alternative to chemical herbicides.

Background: Yellow mosaic disease (YMD) caused by begomoviruses transmitted through the insect vector Bemisia tabaci poses a serious threat to the production of legume crops. Methods: Season-long surveys were carried out for YMD occurrence in six different legume crops and associated natural weeds both symptomatic and asymptomatic across the districts of southern Karnataka, India. The samples were analyzed through RCA PCR using specific primer pairs. Result: Up to 94.1 per cent YMD incidence was recorded and nine weed species were commonly found associated with legume crops. The weeds viz., Ageratum conyzoides, Alternanthera sessilis, Commelina benghalensis and Euphorbia geniculata were abundantly found in the surveyed regions. The weeds were both symptomatic and asymptomatic. Rolling circle amplification coupled polymerase chain reaction method was employed to detect yellow mosaic virus in asymptomatic weeds. Phylogenetic analysis based on the sequences of PCR amplified products of weeds and symptomatic legumes revealed a close clustering of the weed samples with horsegram yellow mosaic virus, legume yellow mosaic virus and mungbean yellow mosaic virus. Overall, our data suggests the role of weed species associated with legume crops as alternative/collateral hosts of begomoviruses and their role in the epidemiology of yellow mosaic disease.

ABSTRACTObjective: Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation in joints. Ageratum conyzoides L. (Babandotan)leaves are proven to be used in inflammation therapy, yet there is a little data regarding the effects of the leaves on RA. The aim of this study is toinvestigate anti-RA activity of the ethanolic extract of A. conyzoides L. leaves (EEAL) harvested from Bogor, Indonesia, in rats.Methods: The phytochemical screening analysis and thin-layer chromatography were performed to analyze the constituents of the EEAL. This studyused white male Sprague Dawley rats which were divided into 6 groups; normal control and negative control groups, both given 0.5% carboxymethylcellulose; the positive control group, given methotrexate suspension (0.05 mg/200 g bw.); the dose variation extract is 40 mg, 80 mg, and 160 mg/200 gbody weight. All the groups were induced with 0.1 ml Complete Freund’s adjuvant on day 1, except normal control group. Some parameters will bemeasured, such as paw edema, levels of leukocyte and lymphocyte, concentrations of tumor necrosis factor-α (TNF-α), and the number of osteoclastsper mm2.Results: For 21 days the rats have given treated the EEAL in three doses, was showed the decreasing volume of paw edema, levels of blood leukocytesand lymphocytes, concentrations of TNF-α and the number of osteoclasts, compared to the rat model of RA.Conclusion: This study showed that the leaves of A. conyzoides L. harvested from Bogor, Indonesia, have activity as anti-RA in a rat model, in whichflavonoid plays a role in inhibition of chronic inflammatory processes.Keywords: Ageratum conyzoides L. leaves, Anti-rheumatoid arthritis, Complete Freund’s adjuvant, Flavonoids.
