(A.1.) Manufacturing Process: Good quality of Khair Tree (Acacia Catechu) is procured from various parts of India. Each log is manually stripped & made free from Sapwood. The heartwood is mechanically chipped into small pieces and cooked under pressure. The liquor obtained contains Catechu which is concentrated in multistage evaporator. On chilling the concentrated liquor crystals of Catechu are produced. Crystals are carefully filtered in controlled conditions. The filtered mass is mashed and cut into Biscuits and slowly dried at low temperatures.

(A.2.) Specifications: Commercially the Catechu (Katha) is valued on the basis of its texture, paste value (8-10 times) and smell. However, detailed analysis of a typical sample is given below:

a) loss on drying

% by weight,

14 – 16

b) Catechin

c) Matter insoluble in rectified spirit,

% by weight,

(C.1) Manufacturing Process : We offer Epi-catechins (L & DL type) from Acacia Catechu and D-Catechins by solvent Extraction of Gambier. We can also offer Gambier –alkaloids (like Gambir Tannine, Oxo-gambir tannine etc.) Shortly we shall introduce Tea-catechins (Epi-gallo Catechins).

(C.2) Specification : In view of rapid transformation of L-Epi catechin to its isomers, at present we can offer limited quantity of 85% pure Epicatechins (L&DL). High purity (99%+) D-Catechins (Hy-drate), are being used by local manufacturers of mouth-freshener.

(C.3) Uses : Both Epicatechins & D-Catechins have demonstrated uses as Antioxidant. It has also proved efficacy in treatment of Acute viral hepatities, and as Anti-diabetic, Anti – inflamatory, Anti-Dirrhoea, Anti-dysentry, Chemo-preventor etc. It is also traditionally used for treatment of Gums & Tooth and skin ailments.
