Aim:
To study the chemical constituents of Glechoma longituba (Nakai) Kupr.
Methods:
Manifold chromatography methods were used to separated the chemical constituents, and the chemical structures were determined by spectral analyses.
Results:
Nine compounds were isolated from Glechoma longituba and identified, as: glecholone (1), 6R,9R-3-oxo-alpha-ionol (2), S(+)-dehydrovomifoliol (3), vomifoliol (4), corosolic acid (5), quercetin (6), stigmastenol (7), myristic acid (8) and triacontanol (9).
Conclusion:
Compound 1 is a new compound. Compounds 2 - 9 were isolated from this plant for the first time.

Exocrine Glands: Methods of Secretion
Merocrine Secretion
Merocrine secretion is the most common type of exocrine secretion. The secretions are enclosed in vesicles and moved to the cell's apical surface, where the contents are released by exocytosis. For example, mucous, a watery secretion rich in the glycoprotein mucin, is a merocrine secretion. The eccrine glands...

Exocrine Glands: Types of Secretions
Serous glands produce watery secretions rich in digestive enzymes and proteins. The constituent cells of the serous gland have centrally located nuclei and eosinophilic secretory granules in the cytoplasm. The parotid gland is an example of a serous gland. It secretes saliva, which contains enzymes, such as lipases and...
