Morinda citrifolia L. has multiple therapeutic properties, particularly as an anti-inflammatory. The species has been widely studied, however, it is necessary to expand studies to document the presence of secondary metabolites and the anti-inflammatory effect of its extracts in animal models. The objective of the present paper was to identify the secondary metabolites present in the ethanol extracts of leaves and fruit of Morinda citrifolia L. collected in the community of San José Rio Manso, municipality of Lalana Choapam, Oaxaca, as well as the evaluation of its anti-inflammatory effect in rabbits. Ethanol extracts were obtained from the green and mature leaves, as well as the juice of the fruit. Green leaf extract gels were prepared and used in a completely randomized experiment in rabbits. The presence of alkaloids, leucoantacionins, amino acids, coumarins, cardiotonics, flavonoids, terpenes and tannins was identified. The 0.5% extract was more efficient at reducing the inflamed area by 55.6% compared to 28.6% of the control, 48 hours after the induction of inflammation. No signs of adverse reactions due to the use of the pharmaceutical forms evaluated were observed.

The inflammatory response is one of natural process in the body to protect itself following tissue injury, but it can cause discomfort. Noni (Morinda citrifolia L.) leaf known as a traditional medicament to help reduce the inflammatory effect. The leaves empirically applied as a wrapping on fever or wound. The purpose of this study was to identify the anti-inflammatory effect of topical noni leaf extract paste in 5% and 10% concentration by examination of Wistar rat paw edema induced by λ-carrageenan. Twenty-four Wistar rats divided into four groups, which were negative control, positive control with diclofenac sodium 1% gel, 5% noni leaf, and 10% noni leaf paste groups. Paw edema was induced by intraplantar injection of 1% λ-carrageenan to every rat. Every treatment subsequently applied in the plantar area before injection, and the changed paw volume measured with plethysmometer at minutes 0, 30, 60, and 90. This study was at the Animal Laboratory, Faculty of Medicine, Universitas Jenderal Achmad Yani, Cimahi city in October–December 2017. The result displayed that the minimum volume after 90 minutes was on 5% and 10% noni leaf paste group, which is 1.00 mL. Kruskal-Wallis test result of inflammatory percentage was significantly different among every group in each examination time (p<0.05). Post-hoc test showed that inflammatory reduction on paw edema with noni leaf paste application on both concentrations were significantly different compared to the negative control. However, it was not different from the positive control group. This study showed that application of noni leaf paste in 5% and 10% concentration could help reduce inflammatory response on skin possibly by the active anti-inflammatory ingredients of noni leaf. EFEK PASTA EKSTRAK DAUN MENGKUDU (MORINDA CITRIFOLIA L.) TOPIKAL TERHADAP EDEMA KAKI TIKUS GALUR WISTAR YANG DIINDUKSI KARAGENANInflamasi adalah proses alami tubuh untuk melindunginya setelah cedera, namun hal tersebut dapat menyebabkan ketidaknyamanan. Daun mengkudu (Morinda citrifolia L.) dikenal sebagai obat tradisional untuk menurunkan efek inflamasi yang secara empiris digunakan untuk mengobati demam dan luka. Tujuan penelitian ini adalah mengetahui efek anti-inflamasi pasta ekstrak daun mengkudu melalui pemeriksaan edema kaki tikus yang diinduksi karagenan-λ. Dua puluh empat tikus galur Wistar dibagi menjadi 4 kelompok, yaitu kontrol negatif dengan akuades, kontrol positif (aplikasi gel Na diklofenak 1%), serta perlakuan pasta daun mengkudu 5% dan 10%. Edema dibuat dengan menginjeksi intraplantar tikus dengan 1% karagenan-λ pada tiap kelompok. Tiap-tiap perlakuan diaplikasikan sebelum tikus diinjeksi dan perubahan volume kaki tikus diukur dengan pletismometer di menit ke-0, 30, 60, dan 90. Penelitian ini dilakukan di Laboratorium Hewan, Fakultas Kedokteran, Universitas Jenderal Achmad Yani, Kota Cimahi pada Oktober–Desember 2017. Hasil pengukuran memperlihatkan penurunan volume edema kaki terkecil setelah 90 menit pada kelompok pasta daun mengkudu 10%, yaitu 1,00 mL. Hasil Uji Kruskal-Wallis terhadap persentase inflamasi berbeda nyata pada tiap kelompok dan tiap waktu pengamatan (p<0,05). Hasil uji beda menunjukkan bahwa penurunan inflamasi kaki tikus pada perlakuan pasta daun mengkudu kedua konsentrasi berbeda nyata dibanding dengan kontrol negatif, tetapi tidak berbeda dengan kontrol positif. Penelitian ini menunjukkan bahwa pasta daun mengkudu 5% dan 10% dapat membantu menurunkan reaksi inflamasi kulit dan efeknya sejalan dengan Na diklofenak karena zat aktif yang bersifat anti-inflamasi dalam daun mengkudu.

Abstract Background Tetracera alnifolia Willd. (Dilleniaceae) is used in traditional African Medicine for the treatment of headache, abdominal pain, and rheumatism. Hence, this study sought to investigate the antinociceptive and anti-inflammatory effects of the hydroethanolic leaf extract of T. alnifolia (HeTA) in rodents. Methods Antinociceptive activity was evaluated using the acetic acid-induced writhing, formalin-/capsaicin-induced paw licking and hot plate tests in mice. The contribution of opioidergic, l-arginine-nitric oxide, and ATP-sensitive potassium channel pathways in HeTA-induced antinociception was also evaluated. The anti-inflammatory effect was assessed using the carrageenan-induced paw edema, xylene ear edema, cotton pellet granuloma, and complete Freund’s adjuvant (CFA)-induced arthritis in rats. Results HeTA (100, 200, and 400 mg/kg, p.o.) produced significant (p<0.05) decrease in mean number of acetic acid-induced writhing, time spent licking paw in formalin, and capsaicin tests as well as time course increase in nociceptive reaction latency in hot plate test. HeTA-induced antinociception was prevented by pretreatment of mice with naloxone (non-selective opioid receptor antagonist), l-arginine (nitric oxide precursor), or glibenclamide (ATP-sensitive potassium channel blocker). HeTA (100 mg/kg, p.o.) produced a significant anti-inflammatory effect against carrageenan-induced rat paw edema (1–5 h), xylene-induced ear edema, cotton pellet-induced granuloma formation, and CFA-induced arthritis in rats. The effects of HeTA in various models were similar to the effect of the standard reference drugs. Conclusions Findings from this study showed that HeTA possesses antinociceptive effect possibly mediated through peripheral opioid receptors with activation of l-arginine-nitric oxide and ATP-sensitive potassium channel pathway as well as anti-inflammatory activity.

Bryophyllum pinnatum (Lam.) Oken (Crassulaceae) is used traditionally to treat many ailments. This study investigated the anti-inflammatory effect of hydro-ethanol leaf extract of Bryophyllum pinnatum on Wistar rats using acute and chronic models and also evaluates the bioactive compounds of the leaf extract. The phytochemical constituents of the plant extract were quantitatively determined by Gas Chromatography-Flame Ionization Detector (GC-FID) and acute anti-inflammatory activity was carried out with the aid of plethysmometer while chronic anti-inflammatory activity was investigated using cotton pellet. Results showed that the leaf extract of B. pinnatum was rich in kaempferol (7.006 ±0.02 μg/g), sapogenin (3.372 ±0.02 μg/g), rutin (1.837 ±0.01 μg/g) and lunamarine (1.359 ±0.01 μg/g). The findings showed that the plant had considerable anti-inflammatory effects in a dose dependent manner, returning edema in carragenean-induced and cotton pellet induced granuloma in Wistar rats to normal within 120 minutes and 7 days respectively. The findings of this work have shown that the leaf of B. pinnatum was rich in bioactive compounds which could be synthesized to produce new plant based product to fight inflammatory disorders with fewer side effects.
