Glycerol or glycerin is a colourless, odourless, viscous liquid that is sweet-tasting and mostly non-toxic. It is widely used in the food industry as a sweetener and humectant and in pharmaceutical formulations. Glycerol is an important component of trigl

DL-Syringaresinol ( (±)-Syringaresinol) is a lignan from ginseng berries with anti-inflammatory, antioxidant, analgesic and weak anti-mycobacterial activities.DL-Syringaresinol can delay oxidative stress-induced skin aging through autophagy, alleviate oxaliplatin-induced neuropathic pain and sepsis-induced cardiac dysfunction by inhibiting inflammatory responses. neuropathic pain and sepsis-induced cardiac dysfunction by inhibiting inflammatory responses.

Qingyangshengenin B (Otophylloside B) is a C-21 steroidal glycoside isolated from Qingyangshen. Qingyangshengenin B protects against Aβ toxicity, which decreases Aβ deposition by decreasing the expression of Aβ at the mRNA level. Qingyangshengenin B has antiepileptic and anti-aging effects, it can extend lifespan, increase heat stress-resistance, delay body paralysis, and increase the chemotaxis response in C. elegans models of Alzheimer's disease. Otophylloside B can suppress the seizure-like locomotor activity caused by pentylenetetrazole in zebrafish.

2alpha,19alpha-Dihydroxy-3-oxo-urs-12-en-28-oic acid has anti-HIV activity. It shows an inhibitory effect on the activation of Epstein-Barr virus early antigen (EBV-EA) induced by 12-O-tetradecanoylphorbol-13-acetate (TPA) and causes a significant delay o

Guajadial C acts as a Top1 catalytic inhibitor and can delay Top1 poison-mediated DNA damage. It shows cytotoxicity against five human cancer cell lines.

Guajadial F acts as a Top1 catalytic inhibitor and can delay Top1 poison-mediated DNA damage. Guajadial F shows cytotoxicity against five human cancer cell lines.

2-Methylsuccinic acid (Pyrotartaric Acid) is a normal metabolite found in human fluids. Increased urinary levels of 2-Methylsuccinic acid (Pyrotartaric Acid) (together with ethylmalonic acid) are the main biochemical measurable features in ethylmalonic encephalopathy, a rare metabolic disorder with an autosomal recessive mode of inheritance that is clinically characterized by neuromotor delay, hyperlactic acidemia, recurrent petechiae, orthostatic acrocyanosis, and chronic diarrhea.

Pyrrole-2-carboxylic acid (Minaline) was first identified as a degradation product of sialic acids, then as a derivative of the oxidation of the D-hydroxyproline isomers by mammalian D-amino acid oxidase. The latter relationship results from the lability of the direct oxidation product, A'-pyrroline-4-hydroxy-2-carboxylic acid, which loses water spontaneously to form the pyrrole. A similar reaction is catalyzed by the more specific allohydroxy-D-proline oxidase of Pseudomonas. In whole animal observations, pyrrole-2-carboxylate (PCA) ' was identified in rat or human urine after administration of the D-isomers of hydroxyproline, a finding ascribable to the action of D-amino acid oxidase. Urinary excretion of N-(pyrrole-2-carboxyl) glycine has been reported in a 5-year-old affected with type II hyperprolinemia; The child has mild developmental delay, recurrent seizures of the grand mal type and EEG alterations.

Scutellarin methyl ester has the effect of improving sleep, such as prolonging sleep time, increasing the incidence of sleep, shortening sleep latency, which also helps to delay aging process.
