Danshensu or salvianic acid A is an alpha hydroxy carboxylic acid. It is found in the plants Salvia miltiorrhiza , and Melissa officinalis . It is a component of some traditional Chinese medicine. [2]
It was discovered in the water soluble extract of roots of Salvia miltiorrhiza . [3] [4] The substance can dissolve in water, methanol, ethanol, ethyl acetate and acetone. In practice the roots are extracted with boiling water. Then ethanol is added to bring the concentration up to %70 ethanal. This causes precipitation of protein, starch and polysaccharides. Chloroform then extracts coloured chemicals from the alcoholic solution. [4]
Danshensu as a racemic form has been made from protocatechuic aldehyde. [4]
Danshensu is sensitive to air or alkaline conditions. It oxidises, polymerises and darkens on exposure. [4]
Danshensu can have its hydroxy groups methylated on treatment with dimethylsulfate. [4] In acid conditions it can convert to salvianolic acid C. [4]
Danshensu dilates cardiac arteries. [5]
It can be sold as a sodium salt.
GABAB receptors (GABABR) are G-protein coupled receptors for gamma-aminobutyric acid (GABA), therefore making them metabotropic receptors, that are linked via G-proteins to potassium channels. The changing potassium concentrations hyperpolarize the cell at the end of an action potential. The reversal potential of the GABAB-mediated IPSP is −100 mV, which is much more hyperpolarized than the GABAA IPSP. GABAB receptors are found in the central nervous system and the autonomic division of the peripheral nervous system.
Kaempferol (3,4′,5,7-tetrahydroxyflavone) is a natural flavonol, a type of flavonoid, found in a variety of plants and plant-derived foods including kale, beans, tea, spinach, and broccoli. Kaempferol is a yellow crystalline solid with a melting point of 276–278 °C (529–532 °F). It is slightly soluble in water and highly soluble in hot ethanol, ethers, and DMSO. Kaempferol is named for 17th-century German naturalist Engelbert Kaempfer.
Salvia miltiorrhiza, also known as red sage, redroot sage, Chinese sage, or danshen, is a perennial plant in the genus Salvia, highly valued for its roots in traditional Chinese medicine. Native to China and Japan, it grows at 90 to 1,200 m elevation, preferring grassy places in forests, hillsides, and along stream banks. The specific epithet miltiorrhiza means "red ochre root".
Shō-saiko-tō (小柴胡湯), also known as minor bupuleurum formula and xiǎocháihútāng (XCHT), is a herbal supplement, believed to enhance liver health. Sho-Saiko-To is a widely used prescription drug in China and is a listed formula in China and Japan as a Kampo medicine. There are currently ongoing clinical trials for Sho-Saiko-To at University of California, San Diego and Memorial Sloan-Kettering Cancer Center. The active ingredients of sho-saiko-to discovered so far include baicalin, baicalein, glycyrrhizin, saikosaponins, ginsenosides, wogonin, and gingerol.
Shennong Bencaojing is a Chinese book on agriculture and medicinal plants, traditionally attributed to Shennong. Researchers believe the text is a compilation of oral traditions, written between the first and second centuries AD. The original text no longer exists, but is said to have been composed of three volumes containing 365 entries on medicaments and their description.
Salidroside (rhodioloside) is a glucoside of tyrosol found in the plant Rhodiola rosea. It has been studied, along with rosavin, as one of the potential compounds responsible for the putative antidepressant and anxiolytic actions of this plant. Salidroside may be more active than rosavin, even though many commercially marketed Rhodiola rosea extracts are standardized for rosavin content rather than salidroside.
Royal Tramp is a 2008 Chinese television series adapted from Louis Cha's novel The Deer and the Cauldron.

The series was first broadcast on Jiangsu TV in China in 2008 and was subsequently aired on TVB in Hong Kong and other countries.
Therapeutic Target Database (TTD) is a pharmaceutical and medical repository constructed by the Innovative Drug Research and Bioinformatics Group (IDRB) at Zhejiang University, China and the Bioinformatics and Drug Design Group at the National University of Singapore. It provides information about known and explored therapeutic protein and nucleic acid targets, the targeted disease, pathway information and the corresponding drugs directed at each of these targets. Detailed knowledge about target function, sequence, 3D structure, ligand binding properties, enzyme nomenclature and drug structure, therapeutic class, and clinical development status. TTD is freely accessible without any login requirement at https://idrblab.org/ttd/.
Huáng bǎi, huáng bó or huáng bò is one of the fifty fundamental herbs of traditional Chinese medicine. Known also as Cortex Phellodendri, it is the bark of one of two species of Phellodendron tree: Phellodendron amurense or Phellodendron chinense.
The Water Margin is a 1998 Chinese television series adapted from Shi Nai'an's classical 14th-century novel of the same title. It was produced by CCTV with Zhang Jizhong as producer. It was first broadcast in China in January 1998. The series also featured action choreography by Yuen Woo-ping.

Graphene quantum dots (GQDs) are graphene nanoparticles with a size less than 100 nm. Due to their exceptional properties such as low toxicity, stable photoluminescence, chemical stability and pronounced quantum confinement effect, GQDs are considered as a novel material for biological, opto-electronics, energy and environmental applications.

Isaria cicadae is an ascomycete fungus that parasitizes cicada larvae. It forms white and yellow asexual fruiting structures resembling synnema. While mostly being found throughout Asia in warm, humid regions, it has been found on various other continents. It is known in Traditional Chinese Medicine as Chan Hua and commonly called “cicada flower.” Its medicinal uses date back to the fifth century AD in China. It can also be used in various foods and tonics.
