BACKGROUND MATERIAL Boric acid (H3BO3, boracic acid, orthoboric acid) is a colorless and odorless compound occurring as crystals, granules or a white powder. It is usually prepared by action of sulfuric acid on borax (sodium borate). Boric acid is used medicinally in ophthalmic solutions, and the powder or solution as an acidifying agent in treating the irritation produced by ammonia from the urine in diapers of infants, and in dermatology in ointments either alone or in combination with other medicinal agents. It has also been employed in gargles, mouth washes and as a preservative. Commercial uses of boric acid are varied, but often include its use in the preparation of face or body powders in which it is added to tale. It is stated that boric acid has a suppressant effect on molds or mildews, or assists in enabling the powder mixtures to flow more freely from the containers. The usual ointment contains 10% boric acid; the standard medicinal solution contains not less than 4.25% boric acid. The United States Food and Drug Administration, on January 30, 1954, issued a statement to the effect that borated talcum powder containing 5% or less of boric acid is safe for use as a dusting powder on babies. The implication here is that powder using more than 5% boric acid would not be safe. Fatalities among adults from the ingestion of boric acid have been reported from as little as 1 teaspoonful of boric acid. Another report indicates that 2 ounces of a 5% solution of boric acid were fatal to an infant.

This research used the lesser known species as much 5 types rattan, consisted of i.e marau (Calamus Mettanensis Becc), toho (Calamus Spp), galang (Daemonorops Verticilaris Griff Mart), hijau (Calamus Spp) and simpurut (Calamus Panajuga Becc) from Central Kalimantan. Preservative used the mixture of boric acid with the borax and copper-8 by  the concentration of 1,0 %, 2,0 % and 3,0 %. Soaked time during 2 day, 4 day and 6 day by immersion chilled. Result of research indicated that the retention value varied, the greater of concentration condensation and soaking period, the greater average the value of retention while penetration result at all of treatment showed the value 100 %.Keywords:  rattan, preservation, retention, penetration, cold soaking.

Arylboronic acids were widely used as efficient catalysts in direct amide formation and other organic transformations. Surprisingly, reports on their use as catalysts in carbohydrates synthesis are very rare even though boron acid-diol complexation was extensively investigated in molecular recognition for saccharides and so on. Here we developed an efficient arylboronic acids catalyzed dimerization of glucosamines forming deoxyfructosazine which is important compound in pharmaceutical and food industries, against a commonly held belief that excess amount of phenyl boronic acid (or boric acid) is a must. A catalytic mechanism was also proposed and arylboronic acids instead of their boronates was identified as catalysts.
