Morphological variables restrict flower choice of Lycaenid butterfly species: implication for pollination and conservation

Background Butterflies make an important part for plant-pollinator guild. These are nectar feeder or occasionally pollen feeder and thus proboscis of the butterfly species are considered as one of the most important variable in relation to the collection of food from plants. In butterfly-plant association, nectar source is principally determined by quality of nectar, corolla length, and nectar quantity. For the butterfly, nectar uptake is determined by proboscis length because flowers with long corolla restrict butterfly species containing shorter proboscis. Empirical studies proved that butterfly species with high wing loading visit clustered flowers and species with low wing loading confined their visit to solitary or less nectar rich flowers. The present study tries to investigate the flower preference of butterfly species from Lycaenidae family having very short proboscis, lower body length, lower body weight and wing span than the most species belonging from Nymphalidae, Pieridae, Papilionidae, and Hesperiidae. Results Butterflies with shorter proboscis cannot access nectar from deeper flower. Although they mainly visit on less deeper flower to sucking nectar, butterflies with high wing loading visits clustered flowers to fulfill their energy requirements. In this study, we demonstrated flower choice of seven butterfly species belonging to Lycanidiae family. The proboscis length maintains a positive relationship with body length and body weight. Body length maintains a positive relationship with body weight and wing span. Wing span indicate a strong positive relationship with body weight. This study proved that these seven butterfly species namely Castalius rosimon (CRN), Taracus nara (TNA), Zizinia otis (ZOT), Zizula hylax (ZHY), Jamides celeno (JCE), Chilades laius (CLA), and Psuedozizeeria maha (PMA) visit frequently in Tridax procumbens (TPR), Ocimum americanum (OAM) and Syndrella nodiflora (SNO). The species do not visit Lantana camara (LCA) and Catharanthus roseus (CRO) plants. Conclusion The present study proved that butterfly species visits frequently in Tridax procumbens (TPR), Ocimum americanum (OAM) but less frequently in Syndrella nodiflora (SNO). So, that study determined the butterfly species helps in pollination of these herbs that in turn helps the conservation of these butterfly species.

A DESCRIPTIVE STUDY AND IN-VITRO ANTIOXIDANT ACTIVITY OF LEAVES EXTRACTS OF TRIDAX PROCUMBENS LINN

Tridax Procumbens Linn is a member of the Asteraceae family. Tridax Procumbens has to be utilized because native medication intended for a number of complaints and problems in humans and animals for thousands of years. It is used widely in Indian conventional remedies for healing of wounds, like anticoagulants, in fungal infection, in diarrhea and dysentery, as an antioxidant, antimicrobial, anti-inflammatory, and immunomodulators. In folk medicine, certain communicable skin diseases are treated by using leaves extract. It's also known as 'Bhringraj,' an ayurvedic drug used to treat liver problems. At least 12,000 people have been separated from their families. These compounds protect plants from pathogens, insects, and herbivores by acting as defensive mechanisms. The aim of the test is to establish the antioxidant potential of the leaves of Tridax Procumbens. The current research is aimed at identifying novel plant directions, and antioxidant activity has been chosen for that reason. Using the maceration procedure, the power of the plant's shade dried leaves was extracted with chloroform water and ethanol. The antioxidant activities of the resulting extracts were evaluated using 2 techniques: nitric oxide scavenging activity and ferric chloride reductive ability. The alcoholic extract in 600 mg/ml and 800 mg/ml and 1000 mg/ml concentration has demonstrated antioxidant activity higher than ascorbic acid (20 mg) by nitric oxide scavenging method. By using a ferric chloride scavenging model, the aqueous and alcoholic extracts at 400 g/ml and 600 g/ml concentrations revealed antioxidant activity near to that of ascorbic acid (20 g).

A Comprehensive Exploration of Pharmacological Properties, Bioactivities And Inhibitory Potentiality of Luteolin From Tridax Procumbens As Anticancer Drug By In-Silico Approach

Tridax procumbens is a flowering plant of the Asteraceae family with a wide range of medicinal uses like anti-inflammatory, anti-diabetic, anti-microbial, immunomodulatory, etc. This study aimed to investigate the anti-cancerous activity of human lung cancer for targeting Luteolin, a phytochemical of Tridax procumbens. The computational study has been done for studying the structural properties of Luteolin. The drug-likeness of the molecule has been predicted by virtual screening of ADMET properties. The molecular docking technique of the in-silico method is performed to check the complex formation between protein and ligand. The reactivity and stability of the molecule are investigated with the help of molecular dynamics (MD) simulations. In the present work, we have tried to establish a strong candidature of any of the phytochemical of Feverfew as an inhibitor against human lung cancer.

Green Synthesized Silver Nanoparticles Using Tridax Procumbens for Topical Application: Excision Wound Model and Histopathological Studies

The objective of this study was to synthesize silver nanoparticles from the leaves of Tridax procumbens and develop its topical gels using chitosan to investigate the wound healing efficacy concomitant with the histopathological study. Green synthesized silver nanoparticles (AgNPs) were prepared by reacting silver nitrate (0.3 M) with leaf extract and characterized by particle analysis, FTIR, XRD, SEM, BET, and TGA. The results revealed formed AgNPs were nano-sized (138 ± 2.1 nm), monodispersed (PDI: 0.460 ± 0.3), inter-particle repulsion (zeta: −20.4 ± 5.20 mV), stabilized, crystalline and, spherical with size ranging from 80–100 nm as per SEM micro photos. The BET analysis of AgNPs presents the surface area (12.861 m2/g), pore volume (0.037 cc/g), and pore radius (24.50 nm).TGA results show a loss of 13.39% up to 300 °C. The topical formulation was developed by loading AgNPs in chitosan-based gels, evaluated by pH, thermal cycling, centrifugal, and spreadability tests. AgNPs chitosan gels results showed skin compatibility, higher stability, and spreading ability. The maximum antibacterial zone of inhibition was found to be 25 ± 0.98 mm for bacillus subtitles and 30 ± 1.99 mm for Klebsiella pneumoniae, respectively. Nanosilver-containing gel also showed excellent compatibility with erythrocytes. Excision wound model was used to assess the wound healing property of the developed AgNP gels, the results of which indicated a significantly progressive healing process in test-group of animals treated with chitosan-based gels containing AgNPs. A histopathological study further confirmed the almost normal skin structure of treated animal tissue compared to standard and negative control. Thus, green synthesized AgNPs loaded chitosan-based topical gel can potentially be used for wound healing application.
