Aktivitas Hepatoprotektif Ekstrak Metanol Buah Lakum (Cayratia trifolia (L.) Domin) Terhadap Diameter Vena Sentralis, Lebar Sinusoid dan Berat Hepar Tikus Putih (Rattus novergicus L.) yang Diinduksi Parasetamol
Get PDFSecondary metabolites of lakum (Cayratia trifolia (L.) Domin) fruit have been evaluated in previous researches. The fruit contains flavonoids, terpenoids and phenols which have antioxidant properties. The aim of this research was to determine the hepatoprotective activity of methanolic extract of lakum fruit in Wistar rats’ liver induced by high doses of paracetamol. Ripe lakum fruits were macerated with methanol as the solvent. Thirty-five male Wistar rats (Rattus novergicus L.) were used in this research and devided into 7 groups (normal, negative, positive, solvent, 115 mg kg-1, 230 mg kg-1, and 345 mg kg-1 of lakum fruit methanolic extract). Results showed that the effect of 230 mg kg-1 of lakum fruit methanolic extract (central vein diameter: 40,20 ± 6,97 µm; sinusoid wide: 5,60 ± 0,94 µm; and liver weight: 6,33 ± 0,98 g) were similar to the effect of silymarin (central vein diameter: 42,99 ± 6,60 µm; sinusoid wide: 4,49 ± 0,44 µm; and liver weight: 6,58 ± 0,88 g) as the standard drug

Get PDFNepenthes spp. is one of the ornamental plants in Indonesia that has much uniquenesses on its pitcher cup in shape and colour. The purpose of this research is to recognize the variety of morphometric characters and to know the grouping of Kantong Semar species (Nepenthes spp.) in Simpang Kasturi Village, Mandor District. The study was conducted for 3 months from October to December 2017 at Simpang Kasturi Village Forest, Mandor District. Identification, data processing, and the making of herbarium were done in Biology Laboratory of Biology Department, Mathematics and Natural Science Faculty of Tanjungpura University, Pontianak. The research method was done using the survey method following by sampling processes performed by taking samples of leaves, stems, and pitcher cup. Samples then were observed based on morphological characteristics of leaves, tendrils, stems and pitcher cup. Furthermore, collected data were analyzed using cluster analysis (grouping analysis) with SPSS 21 program. The results of this study found 5 individuals from 4 species of Nepenthes which have different morphometric characters among themselves. The most various morphological character among the species is the morphological character of the pitcher cup. Nepenthes rafflesiana has the largest pitcher cup size while Nepenthes gracilis has the smallest one size. Based on the coefficient value, the most significant grouping is Nepenthes rafflesiana with Nepenthes mirabilis, while the closest one is Nepenthes ampullaria 1 with Nepenthes ampullaria 2

Pertumbuhan Stek Batang Nepenthes reinwardtiana Miq. Setelah Direndam Dengan Urin Kambing
Get PDFNepenthes reinwardtiana Miq. is one of the species of Nepenthes found in west Borneo where its population in nature is declining. Ex-situ conservation efforts by cultivating vegetatively through stem cuttings need to be done to overcome the extinction of N.reinwardtiana. One of the factors that determines the growth of cuttings is the content of the external growth regulator namely auxin. One of the sources of organic auxin that can be used is goat urine. This research was conducted to find out the effects of goat urine on the growth of stem cuttings of N.reinwardtiana and to find out the concentration of goat urine that provides the best growth on N.reinwardtiana stem cuttings. The method used is completely randomized design with 4 treatments which is goat urine concentration of 0,15,30 and 40% , each treatment is repeated 3 times so that 12 units of experiment were obtained. The results show that immersion of goat urine has significant effect on the time of shoot, the number of roots and height of the plant but does not provide the number of shoots. Goat urine concentration of 15% produces that fastest shoot growth namely 11.23 days while the concentration of 30% gives the best result on the number of roots as many 2 pieces and the height of the plant namely 4.17 cm
