Phytochemical study of an ethno medicinal plant Limnophila rugosa Roth. (Merr) (Scrophulariaceae) whole plant

Limnophila rugosa Roth. (Merr) (Scrophulariaceae) is used as a botanical source of Bhringaraja by the traditional practitioners of Balangir and Baragarh district of Odisha. The present study was carried out to screen the preliminary phytochemical constituents of ethanol & aqueous extracts of the whole parts of L. rugosa including High Performance Thin Layer Chromatography. The extracts were subjected to various chemical tests in order to identify the main phytoconstituents of the plant. The study revealed that the ethanol extract contains glycosides, little amount of alkaloids and flavonoids where as the aqueous extract is rich in glycosides.

Journal of Pharmacognosy and Phytochemistry, 2019

Limnophila indica L. (Druce) is being estimated for the essential oil composition, in-vitro antioxidant, anti-inflammatory and insect antifeeding activity of this plant was evaluated. The GC-MS analysis led to identification of thirty-five compounds comprising of 90.9% of total oil composition. The major compound of the oil identified was epi-cyclocolorenone (27.7%). The oil was screened for antioxidant activity using reducing power assay, metal chelating of Fe assay, NO and DPPH radical scavenging assay with IC50 21.19±0.06, 22.77±0.11, 15.74±0.06 and 14.52±0.05 μg/ml respectively. In-vitro antiinflammatory activity assessment of the essential oil results in its activity with IC50 19.28±0.06 μg/ml. And also showed potent insect antifeeding action in a sequentially dose dependent manner against Spilosoma obliqua.

Review on scientific basis for the therapeutic use of Limnophila rugosa (Roth.) Merr.-an extra-Pharmacopoeial drug

Bhringaraj is one of the potent Rasayana drug in the classical texts of Ayurveda. Ayurvedic lexicon (Rajnighantu) considered three varieties of Bhringaraja i.e. Sweta, pitta and Neela. Among, this Neela variety is considered as best one. The botanical identity of Sweta and Pitta is considered as Eclipt aalba and Wedelia chinesis respectively. Till, now botanical identity Neela Bhringaraj is lacking. The traditional practitioners and tribal people of surrounding area of Gandhamardan hill region of Odisha used a plant, Limnophila rugosa (Roth.) Merr. of family Scrophulariaeae, with blue colour flower, in the name of Bhringaraj. The present work offers a review addressing the pharmacognosy, pharmacology, and phytochemistry of Limnophila rugosa (Roth) Merr. (belonging to Scrophulariaceae family) regarded as one of the most significant plant species in traditional system of medicine. The plant is used in the treatment of various ailments like pestilent fever, elephantiasis, diarrhoea, dysentery, dyspepsia etc. and is a diverse kind of chemical constituents such as phenolics, flavonoids, terpenoids, amino acids etc. The isolated phytochemicals as well as different extracts exhibited significant biological activities such as antimicrobial, anti-inflammatory, diuretic, hypotensive and effects on Guinea-pig ileum. Exhaustive research regarding isolation of more phytochemicals and pharmacology study on this medicinal plant is still necessary so as to explore the plant regarding its medicinal importance. Therefore, the aim of this review is to boost up the present day researchers in this direction to undertake further investigation of this plant. The present review covers floras, websites, databases, journals and classical texts for gathering of information on different aspects on Limnophila rugosa (Roth.) Merr.

Chemical composition, total phenolics assay and biological activities of chloroform extract from Limnophila indica (L.) Druce

Journal of entomology and zoology studies, 2019

Present research was undertaken to investigate the chemical composition, total phenolics assay, in vitro antioxidant, anti-inflammatory and insect antifeeding activity in chloroform extract of Limnophila indica (L.) Druce. GC-MS analysis revealed the occurrence of 4,5-Dimethyl-1,2,3,6,7,8,8a,8boctahydrobiphenylene (18.3%) as a major compound. Total phenolic content, flavanoid content and orthodihydric phenol in the extract were 150.55±0.33 mg/g GAE, 40.72±0.69 mg/g CNE and 56.66±0.93 mg/g CLE, respectively.

Evaluation of antimicrobial activity of Limnophila heterophylla (Roxb.) Benth. (Scrophulariaceae) whole plant

International Journal of Ayurvedic Medicine, 2013

Antibacterial and antifungal activity of the Limnophila heterophylla (Roxb.) Benth. whole plant methanol extract against four pathogenic bacterial strains two Gram positive (B. subtilis & S. aureus), two Gram negative (E. coli and K. pneumonia) and two fungal strains (S. flavus & C. albicans) in different concentrations (5μg/ml, 25μg/ml, 50μg/ml, 100μg/ml, 250μg/ml), were evaluated following standard procedure. A zone of inhibition of extract was compared with that of different standards like Streptomycin, Cefpodoxime and Gentamycin for antibacterial activity, Amphotericin B, Fluconazole and Clotrimazole for antifungal activity. The extract showed remarkable inhibition of antibacterial and antifungal activities comparable with that of standard against the organisms tested.

Anti-inflammatory and Analgesic Effects of Limnophila repens (Benth.)

Turkish journal of pharmaceutical sciences, 2020

Amaç: Limnophila repens (MELR) metanol ekstresinin analjezik ve anti-enflamatuvar etkileri 200 ve 400 mg/kg dozda değerlendirildi. Gereç ve Yöntemler: Karagenin ile indüklenen pence ödeminde MELR'nin anti-enflamatuvar etkisi araştırıldı ve analjezik aktivite merkezi ve periferik modellerle değerlendirildi. Bulgular: MELR, farklı dozlarda (200 ve 400 mg/kg) güçlü analjezik ve anti-enflamatuvar etki göstermiştir. Çalışma sonuçları, Limnophila'nın hem analjezik hem de anti-enflamatuvar olarak kullanımını doğrulamıştır. Güçlü anti-enflamatuvar ve analjezik etkilerden anabolik steroidlerin (β-sitosterol ve stigmasterol gibi); flavonoidlerin (kuersetin ve glikozitler gibi) sorumlu olabileceği değerlendirilmiştir. Sonuç: Çalışmaya dayanarak Limnophila repens'in analjezik ve anti-enflamatuvar aktiviteye sahip olduğu sonucuna varabiliriz. Bununla birlikte, organik çalışmalara ek olarak, antinosiseptif ve anti-enflamatuvar etkilerden sorumlu ekstra enerjik kimyasalları değerlendirmek için ek fitokimyasallar gereklidir. Anahtar kelimeler: Limnophila repens, karagenin, fitokimyasal tarama, β-sitosterol Objectives: The analgesic and anti-inflammatory effects of methanolic extract of Limnophila repens (MELR) were assessed at 200 and 400 mg/kg. Materials and Methods: In carrageenan-mediated paw edema, the anti-inflammatory effect of MELR was investigated and analgesic activity was assessed by central and peripheral models Results: MELR had strong analgesic and anti-inflammatory effects at different dosages (200 and 400 mg/kg). The study results confirmed the use of Limnophila as both an analgesic and anti-inflammatory. The strong anti-inflammatory and analgesic effects can be caused by anabolic steroids, i.e. β-sitosterol and stigmasterol; and flavonoids, i.e. quercetin and glycosides, in the extraction of some kind of inflamed arbitrators. Conclusion: Based on the study, we can conclude that Limnophila repens had analgesic and anti-inflammatory activity. In addition to organic studies, however, additional phytochemicals are required to evaluate the extra energetic chemicals responsible for the antinociceptive and antiinflammatory effects.
