Organic and Inorganic Analysis of Rhaphidophora pinnata (l.f.) Schott Water Extract

Abstract

BACKGROUND: Rhaphidophora pinnata (L.f.) Schott is one of the Indonesian plants, has known as a medicinal plant. This plant is a vine; round stems have sticky roots and hanging roots. The leaves have been used as traditional anticancer in Singapore. Indonesian people have also used R. pinnata plants as a diuretic agent, anticancer and antibacterial. R. pinnata plants contain active substances from alkaloid compounds, flavonoids, saponins, tannins and triterpenoids/steroids.

AIM: The purpose of this study was to determine the organic and inorganic content of Rhaphidophora pinnata (L.f.) Schott water extract in the form of fresh leaves, micro simplicia and nano simplicia.

METHOD: The collected R. pinnata leaves are drained and grinded to make micro, and nano Simplicia powder of R. pinnata leaves. The size characterisation of R. pinnata leaves was analysing using Particles Size Analyzer. The water extract of R. pinnata leaves, micro simplicia, and nano simplicia R. pinnata leaves was made 10% (w / v) in water. Phytochemical screening of nano simplicia and nano simplicia water extract included an examination of alkaloid compounds, flavonoids, saponins, tannins, glycosides, and steroids/triterpenoids. Thin-layer chromatography analysis of water extract was analysed using TLC scanner. The element that contains in the water extract was analysed using atomic absorption spectrophotometry methods.

RESULT: The results of phytochemical screening of nano simplicia powder and nano simplicia water extract showed the presence of flavonoids, alkaloids, saponins, tannins, and glycosides. Eluent, which shows good elution is n-butanol: acetic acid: water (6: 2: 2). This eluent is used to elute polar and semipolar compounds and is very good for separating flavonoids. R. pinnata water extract contains the minerals potassium, sodium, magnesium and calcium.

CONCLUSION: R. pinnata water extract contains organic compounds in the form of flavonoids, alkaloids, saponins, tannins, and glycosides. The nano simplicia water extract showed more chemical content than other water extracts on the TLC plate by detection at a wavelength of 250 nm and 300 nm. The most element content in R. pinnata water extract is potassium, followed by magnesium, sodium, and calcium.
