Benefits of technology

The present invention provides a process for preparing a water-soluble Labisia pumila extract from dried Labisia pumila plant material. The process involves extracting the plant material with water to form a water-soluble extract, and optionally drying it. The resulting extract is then analyzed using various techniques such as nuclear magnetic resonance spectrometry, liquid chromatography mass spectrometry, and ultraviolet spectrophotometry to determine its structure. The invention also provides a method for isolating a marker compound from the extract. The use of water as the solvent in the process ensures safety for the potential use of Labisia pumila in various applications.

Problems solved by technology

Labisia pothoina) in the food industries, the reproducibility of extraction processes is still in doubt due to the lack of reliable chemical profiling methods.

example 1

[0038]In one embodiment, 100 kg of Labisia pumila dried and ground plant material is subjected to extraction by heating in 600 L of water at 80° C. over a period of 3 hours and with continuous stirring. The solvent is replaced with an equal volume of fresh solvent at the end of the extracting period and the plant material re-extracted. The mixtures are pooled together, then filtered and filtrate subjected to spray drying. The spray tower conditions are as follows; tower inlet and outlet temperatures are set at 185° C. and 107° C., respectively. The yield of water-soluble extract powder is 4-5%.

example 2

[0039]In another embodiment, 150 kg of Labisia pumila dried and ground plant material is subjected to extraction by heating in 900 L of water at 80° C. over a period of 6 hours and with continuous stirring. The solvent is replaced with an equal volume of fresh solvent at the end of the extracting period and the plant material re-extracted. The mixtures are pooled together, then filtered and filtrate subjected to spray drying. The spray tower conditions are as follows; tower inlet and outlet temperatures are set at 185° C. and 107° C., respectively. The yield of water-soluble extract powder is 4-5%.

Chemical Profiling

[0040]A conventional method is used to profile the extract which is water-soluble, chemically.

[0041]In the present invention, reverse-phase high performance liquid chromatography (HPLC) is typically used, and a conventional detector, for example, an ultraviolet, diode array or photodiode array detector (wavelength set at 254 nm) can be used for detection.

Abstract

A process for the preparation of Labisia pumila extract from Labisia pumila plant material and to obtain an optimized and reproducible chemical profile by high performance liquid chromatography.

Description

RELATED APPLICATION[0001]This application is a divisional of U.S. patent application Ser. No. 11 / 330,701, filed Jan. 12, 2006, which is incorporated by reference herein in its entirety.TECHNICAL FIELD OF THE INVENTION[0002]The present invention relates generally to a process for preparation of plant extract and more particularly to the process for preparation of water-soluble Labisia pumila extract, and to obtain a reproducible chemical profile by reverse-phase high performance liquid chromatography (HPLC).BACKGROUND OF THE INVENTION[0003]Traditional Malay medicine dictates that “kacip fatimah” (or Selusoh fatimah, Rumput siti fatimah, Akar fatimah, Kachit fatimah, Kachip Fatima, Kachip patima, Kunchi fatimah, Pokok pinggang, Rumput palis, Tadah mata hari, Mata pelandok rimba, Bunga belangkas hutan), as disclosed in Burkhill (1993) is used much in childbirth. A decoction of the plant is given not only after childbirth as a protective medicine, but before to expedite labour. Addition...
