The price of dried Aloes in India ranges from Rs to Rs per kg depending upon the `aloin'content and colour of the dried leaves. Aloe gels are expensive. Owing to the increased preference to herbal cosmetics, the demand for Aloe vera is on the rise every year. Aloin, is present in varying amounts according to source, a neutral principle, chiefly from Curacao and Socrotine aloes, barbaloin (in Barbados aloes), resin ( percent), emodin (the purgative principle of aloes)(8 percent), a volatile oil (very slight), and ash (1 to 4 percent).
(13) Aloin is widely used in chronic constipation. Because ofthe absence of resin, the cathartic action of aloin is relatively milder than aloe. It is often used in combination with belladonna to overcome the tendency to griping although action of belladonna is rapid and brief compared to aloe. Aloin may produce renal irritation (U.S.D., , 50). Aloe has been used medicinally for more than years. Egyptian texts, dating to about BCE, describe its healing properties. Alexander the Great used it to treat wounds. Greece, Rome, China, India, West Indies all used it as a wound healer, laxative, and purgative. Cleopatra is said to .
Physicochemical properties of a blend of 10% Aloe vera gel with 5% pitaya juice subjected to UV-C doses of , , and 40 mJ/cm2 were evaluated at pH and Unprocessed treatments were used as the control. The a* color parameter decreased and luminosity increased at pH The decrease in the reddish color was consistent with the decrease in total betalains content and stabilized at. Aloin, also known as barbaloin, is a bitter, yellow-brown colored compound noted in the exudate of at least 68 Aloe species at levels from to % of leaf dry weight (making between 3% and 35% of the total exudate) (Groom & Reynolds, ), and in another 17 species at indeterminate levels [Reynolds, b]. It is used as a stimulant-laxative, treating constipation by inducing bowel movements.

Use the juice of the leaves. The activity of aloe is due to the presence of emodin (trioxi-metilantraquinona) and the principle called Aloin, but also contains resins, a small quantity of volatile oil, and from 1 to 4% mineral salts.
The proportion of aloin varies between and 10% in Socotorine Aloe and between 18 and 25% in that of Barbados. Aloes are a large genus of plants, about species, from sub-Saharan Africa, Madagascar, and parts of Arabia. Many species are widespread in warm or tropical semi-arid regions, yet the distribution of others is limited to a few living in desert or wet mountainous regions.
While some species have been adopted as medicinal plants since ancient time/5(3). Curacao-aloin, C17H20O7, identical with barb-aloin, ugand-aloin, cap-aloin, when boiled with nitric acid - chrysammic acid, crimson color; soc-aloin, C15H16O7, with nitric acid - no color change; nat-aloin dissolved in sulphuric acid in proximity to glass rod dipped into nitric acid - solution green, blue, violet, orange-red - but no effect on.
Aloin gives no apparent change with tartar emetic nor with ferrous salts, but with ferric salts it strikes an olive coloration, which is destroyed by reducing agents.
III. The substance termed resin, which abounds in all kinds of aloes, is not very happily so-called, for it is soluble in considerable quantity in hot water. The principal resin present in the aloes is known as aloesin.
Socotrine and Zanzibar aloes: Colour comparatively lesser change in colour. Though, both aloes and aloin are official drugs, the former is mostly used as a purgative by exerting its action mainly on colon, whereas the latter is generally prepared over the former now-a-days.
Clear gel (in the leaves), yellow sap from the base (bitter aloes) The anthraquinone glycosides (aloin and aloe-emodin) are strongly laxative and can cause uterine contractions. This is the reason that aloes are contraindicated internally during pregnancy.

aloesin. UP The crystalline aloin is accompanied by an amorphous aloin, β-barbaloin, which may be produced by heating barbaloin for about three hours to °°; it is isomeric with barbaloin, and constitutes part at least of the water-soluble substances other than barbaloin and isobarbaloin.
β-barbaloin is particularly abundant in Cape and Uganda aloes. Other constituents are amorphous Aloin, resin and Aloe-emodin. The proportion in which the Aloins are present in the respective Aloes is not accurately known. The manner in which the evaporation is conducted has a marked effect on the appearance of the Aloes, slow and moderate concentration tending to induce crystallization of the Aloin, thus.
By A. Brown aloin is considered not more active than an equal dose of aloes, and the resin inert, while Proctor’s personal experience is that aloes, aloin, uncrystallizable extract and insoluble portion all acted equally well.
That the solubility of aloin in water should be variously stated as 1 in 60, 1 in 90, and 1 inand as. The method of preparation of aloe is different in West Indies and in South Africa. (1) Curacao of Barbados Aloe: In West Indies the cut the leaves are arranged with their cut surface on the inner side, on the slides of V-shaped vessel of about 1 to meter long and the flowing juice collected in a tin vessel placed below the V-shape vessel.
Aloe vera supports a substantial global trade yet its wild origins, and explanations for its popularity over related Aloe species in one of the world’s largest succulent groups, have remained uncertain.
