Identification of Chemical Content and Antihypertensive Activity Test of Ethanol Extract from Tali Bamboo Shoot (Gigantochloa apus (Schult. Schult.F.))

摘要

Tali bamboo shoot is young shoot of bamboo potential to treat several diseases, one of them is hypertension. The aim of this study was to qualitatively identify chemical compounds and to determine antihypertensive activity of Tali bamboo ethanol extract. Extraction method applied in this experiment was maceration using ethanol 70 percent solvent. Qualitative identification toward Tali bamboo shoot powder and extract conducted using chemical reactor. Antihypertensive examination used male white rats Sprague-Dawley divided into 5 groups 5 rats each. Group I negative control (CMC Na 1percent), group II: positive control (Hydrochlorothiazide), Group III: Tali bamboo ethanol extract dose 40 mg/Kg rat body weight, Group IV: dose 80 mg/Kg rat body weight, and group V: dose 160 mg/Kg rat body weight. The results of study indicate that Tali bamboo shoot powder and ethanol extract contain flavonoid, phenolic, saponins and tannins. Tali bamboo shoot ethanol extract indicated decrease of systolic blood pressure activity in male white rats Sprague-Dawley at dose of 40 mg/Kg rat body weight, 80 mg/Kg rat body weight dan rat 160 mg/Kg body weight.
