It can be classified either as a methyl-pentose or a 6-deoxy-hexose. Rhamnose occurs in nature in its L-form as L-rhamnose (6-deoxy-L-mannose). This is unusual since most of the naturally-occurring sugars are in D-form. Exceptions are the methyl pentoses L-fucose and L-rhamnose and the pentose L-arabinose.L-Rhamnose can be isolated from Buckthorn (Rhamnus) and poison sumac. It is also found as a glycoside in a variety of other plants. Rhamnose is a component of the outer cell membrane of acid-fast bacteria in the Mycobacterium genus, which includes the organsism that causes tuberculosis【CHEMICAL ANALYSIS】    ITEMSRESULTSAssay(HPLC)≥98%Loss on Drying≤10.0%Sulphated ashes≤0.1%Heavy metals≤10ppmMelting Range90-94℃(Monohydrate)Specific Rotation+8.8°-9.15°Related SubstancesConform prescribedAppearance of Solution(10% w/v Apueous Solution)Clear and colouless 【PACKAGE】：Packed in paper-drums and two plastic-bags inside.N.W.:25kgs .【STORAGE】：Keep in cool, dry and dark place, avoid high temperature.【SHELF LIFE】：24 months
