Mucilaginous preparations

Aloe vera gel is a mucilaginous preparation obtained from the leaves of Aloe vera (syn. Aloe barbadensis) once the sap has been drained away. It is widely used in cosmetic products for its purported emollient and moisturizing effects. It is claimed to have antibacterial, antifungal, and anti-inflammatory properties and has been proposed as a potentially useful agent for radiation and thermal wounds (see Chapter 12). 

Aloe latex contains anthraquinones and is completely different from aloe gel, a colorless gelatin obtained from the central portion of the aloe leaf. The mucilaginous parenchymous tissue is excised from fresh leaves and immediately utilized for pharmaceutical preparations, or lyophilized and kept dry until use. During extraction of the gel, it is practically impossible to prevent contamination by the leaf latex as the leaves are cut. On the other hand, in intact leaves, anthraquinones may diffuse into gel from the bundle sheath cells. To reduce such contamination, the starting material must be from varieties of aloe with a reduced anthraquinone content.

Description The CTLC in general is a convenient method to achieve good separations over the short distance of 5-6 cm. Extracts and reference compounds are applied in the inner circle (.start) in an overlapping mode, to make sure that compounds are clearly idenlifted by references. Balla,st sub,stances of the extracts. such as mucilagines are diluted in the circular. separation lines. The disturbance and R, value depression of sennoside A.B are reduced (preparation see 2.4 Circular TLC). 

Flaxseeds— These seeds, when ground, have long been used as the basis of various natural laxative preparations. They contain a mucilaginous material which thickens the porridge that is formed when they are cooked in water with other grains. Their bland taste makes it convenient to add them to various cereal products, where their ample supply of calcium, iron, and magnesium adds to the mineral values.
