Abstract

DNA extraction is the first step to study plant systematic and biodiversity analysis usingmolecular markers. This study aimed to conduct DNA extraction from herbarium materialsusing different extraction methods. A total of 0.05 grams of herbarium powders ofCalantheemarginata (Blume) Lindl. and Goodyera procera(Ker-Gawl) Hook. (terrestrialorchid) were used for samples by three different methods. The first method was from Doyleand Doyle with modification of incubation time for 1,5 hours at 65oC and increasing EDTAconcentration to 50 mM. Second method was Dellaporta et al. with modification of incubationtime for 1,5 hours (at 65oC) and increasing EDTA concentration to 100 mM. Third methodwas Rogers and Bendich with modification of incubation time for 1,5 hours (65oC) andadding ethanol twice. The results of electrophoresis revealed that method of Doyle and Doyleobtained DNA from C. emarginata herbarium, while method from Rogers and Bendich,unfortunately it was inconsistent. The method from Dellaporta et al.obtained DNA from G.procera herbarium, while method from Doyle and Doyle revealed inconsistent DNA forG.procera. PCR-RAPD revealed the quality of DNA isolated using Doyle and Doyle methodwas not optimal, showed by unclear patterns of DNA bands. PCR-RAPD using DNA isolatedwith method from Rogers and Bendich revealed clearer DNA bands but only for small sizefragment.Keywords : orchid, DNA extraction, herbarium, PCR

Abstract

Red calliandra (Calliandra calothyrsus Meissn.) leaf have the potential as phytoestrogens. In this study, adult female ovariectomized rats (as a model of menopause women) were given calliandra leaf extract containing estrogenic flavonoids. This study was an experimental design with a Completely Randomized Design (CRD). Forty-five ovariectomized female rats were divided into five groups i.e. untreated control (K), and the treatment group given 80% of C. calothyrsus ethanolic leaves extract doses 25 mg/ kg bw (P1), 50 mg/ kg bw (P2), 75 mg/ kg bw (P3) and 100 mg/ kg bw (P4). The test suspension was given once a day at 24-hour intervals by gavage as much as 0.5 ml/rat/day for two months. At the end of the treatments, blood was collected for blood biochemical tests including hemoglobin levels, hematocrit values, blood glucose and proteins levels. The results showed that C. calothyrsus leaf extract did not negatively affect the health status of the animals through blood biochemical parameters, i.e. hemoglobin levels, hematocrit values, and glucose and protein levels of ovariectomized female rats.
