We investigated the antioxidant and anti-inflammatory effects of a 70% v/v ethanol extract of the stem bark of Antrocaryon micraster on murine models of carrageenan-induced pleurisy and paw oedema. Rat pleural fluid was analysed for volume, protein content, and leucocytes, while lung histology was assessed for damage. Lung tissue homogenates were assayed for glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), and myeloperoxidase (MPO). Phytochemical analysis was carried out on the stem bark. Acute toxicity studies were conducted in rats. In the pleurisy model the extract (30–300 mg/kg) significantly reduced the volume and amount of proteins and leucocytes in the exudate and also protected against lung injury. Tissue level of GSH and SOD and CAT expression were increased while MDA level and MPO activity were reduced. The peak and total oedema responses were significantly suppressed when given both preemptively and curatively in the mice paw oedema test. Saponins, alkaloids, triterpenoids, and tannins were present in the stem bark. A. micraster extract exhibited no apparent acute toxicity. We conclude that the ethanolic stem-bark extract of A. micraster has antioxidant action and exhibits significant anti-inflammatory activity through suppression of pleurisy and paw oedema induced with carrageenan.

Kulit buah Cempedak yang digoreng (Manday) merupakan salah satu makanan yang umum dikonsumsi masyarakat di Kalimantan Selatan. Berdasarkan pengalaman dari beberapa masyarakat, keluhan yang sering terjadi adalah perut terasa perih dan kepala pusing. Evaluasi sifat toksik dari bagian tumbuhan yang dikonsumsi oleh masyarakat sangat penting untuk dilakukan dengan mempertimbangkan perlindungan kesehatan masyarakat karena paparan senyawa kimia dari bagian tumbuhan yang dapat menyebabkan efek yang tidak diinginkan pada masyarakat. Penelitian ini bertujuan untuk mengidentifikasi senyawa kimia dan efek toksisitas akut dari ekstrak etanol kulit buah cempedak. Kulit buah cempedak dikeringkan dengan menggunakan oven. Ekstraksi kulit buah cempedak menggunakan cara maserasi dengan cairan penyari etanol. Tikus uji diberi larutan kontrol Na CMC dan ekstrak dengan dosis 300 mg/kgBB, 1000 mg/kgBB, 2000 mg/kgBB, dan 5000 mg/kgBB. Hasil identifikasi senyawa kimia didapatkan positif mengandung triterpenoid, flavonoid, tanin, dan senyawa fenolik. Tikus uji yang menerima ekstrak dengan dosis 1000 mg/kgBB, 2000 mg/kgBB, dan 5000 mg/kgBB terjadi perubahan pada tikus uji berdasarkan pengamatan fisik yaitu mengalami peningkatan detak jantung atau takikardi, pernapasan cepat, tremor, dan agresif. Kata kunci: Kulit buah cempedak, senyawa kimia, toksisitas akut Rind of Cempedak fruit (Manday) is one of the foods commonly consumed by people in South Kalimantan. Based on the experience of several communities, complaints that often occur are sore stomach and headache. Evaluation of the toxic properties of plant parts consumed by the community is very important to be done by considering public health protection due to exposure to chemical compounds from parts of plants that can cause undesirable effects on the community. This study aims to identify chemical compounds and acute toxicity effects of ethanol extract rind of cempedak fruit. Rind of Cempedak fruit has dried using an oven. Extraction of cempedak fruit skin using maceration method with ethanol. Test rats were given Na CMC as a control and extract with dose 300 mg / kgBB, 1000 mg / kgBB, 2000 mg / kgBB, and 5000 mg / kgBB. The results of the identification of chemical compounds were obtained positively containing triterpenoids, flavonoids, tannins, and phenolic compounds. The test rats that received extracts at a dose of 1000 mg / kgBW, 2000 mg / kgBB, and 5000 mg / kgBW were changed in the test rats based on physical observations that experienced an increase in heart rate or tachycardia, rapid breathing, tremor, and aggressive. Keywords: acute toxicity, chemistry compounds, rind of cempedak fruit

An aphrodisiac is a type of food or drink that has the effect of making those who eat or drink it more aroused in a sexual way. Aphrodisiacs can be categorized according to their mode of action into three groups: substances that increase libido (i.e. sexual arousal), substances that increase sexual potency (i.e. effectiveness of erection) and substances that increase sexual pleasure. Fadogia agrestis (Schweing. Ex. Hiern), Rubiacea (Hausa: Bakin gagai; English name: Black aphrodisiac) is an erect shrub 1-3 feets high. Fadogia agrestis is a medicinal plant widely used for its reported antibacterial and aphrodisiac activities. The aim of this work is to carry out pharmacognostic standardization and safety profile on Fadogia agrestis root. Chemomicroscopic, physicochemical, elemental, phytochemical and acute toxicity studies were carried out using standard methods. The results obtained also provided scientific basis for the use of in folklore medicine. Chemomicroscopic characters present include; cellulosecell wall, lignified cell wall, tannins, starch, calcium oxalate and cutin. The physicochemical parameters evaluated include: moisture content (7.0%), total ash (10.5%), water soluble ash (4.1%), acid insoluble ash (8.33%), ethanol extract (15.0%), and water extractive value (12.0%). The quantitative phytochemical analysis showed that alkaloids (84.0 mg/g) was the highest phytochemical detected in the stem bark while the lowest was saponins (4.0 mg/g).LD50 of both extracts was above 5000 mg/kg and did not cause mortality in all the tested rats. The results of this investigation may be useful for deriving doses that are safe for human consumption of F. agrestis root.
