Rosmarinic acid is an ester of caffeic acid and 3,4-dihydroxyphenyllactic acid. It is commonly found in species of the Boraginaceae and the subfamily Nepetoideae of the Lamiaceae. It is a red-orange powder that is slightly soluble in water, but well soluble is most organic solvents. Rosmarinic acid is one of the polyphenolic substances contained in culinary herbs such as perilla (Perilla frutescens L.), rosemary (Rosmarinus officinalis L.), sage (Salvia officinalis L.), mint (Mentha arvense L.), and basil (Ocimum basilicum L.). These herbs are commonly grown in the garden as kitchen herbs, and while used to add flavor in cooking, are also known to have several potent physiological effects (PMID: 12482446, 15120569). BioTransformer predicts that rosmarinic acid is a product of methylrosmarinic acid metabolism via a hydrolysis-of-carboxylic-acid-ester-pattern1 reaction occurring in humans and human gut microbiota and catalyzed by the liver carboxylesterase 1 (P23141) enzyme (PMID: 30612223). (R)-rosmarinic acid is a stereoisomer of rosmarinic acid having (R)-configuration. It has a role as a plant metabolite and a geroprotector. It is a conjugate acid of a (R)-rosmarinate. It is an enantiomer of a (S)-rosmarinic acid. Rosmarinic acid is a natural product found in Dimetia scandens, Scrophularia scorodonia, and other organisms with data available.

Ursolic acid is a ubiquitous triterpenoid in plant kingdom, medicinal herbs, and is an integral part of the human diet. During the last decade over 700 research articles have been published on triterpenoids research, reflecting tremendous interest and progress in our understanding of these compounds. This included the isolation and purification of these tritepernoids from various plants and herbs, the chemical modifications to make more effective and water soluble derivatives, the pharmacological research on their beneficial effects, the toxicity studies, and the clinical use of these triterpenoids in various diseases including anticancer chemotherapies. Ursolic acid (UA), a pentacyclic triterpene acid, has been isolated from many kinds of medicinal plants, such as Eriobotrya japonica, Rosmarinns officinalis, Melaleuca leucadendron, Ocimum sanctum and Glechoma hederaceae.

C29H50O (414.386145)


beta-Sitosterol, a main dietary phytosterol found in plants, may have the potential for prevention and therapy for human cancer. Phytosterols are plant sterols found in foods such as oils, nuts, and vegetables. Phytosterols, in the same way as cholesterol, contain a double bond and are susceptible to oxidation, and are characterized by anti-carcinogenic and anti-atherogenic properties (PMID:13129445, 11432711). beta-Sitosterol is a phytopharmacological extract containing a mixture of phytosterols, with smaller amounts of other sterols, bonded with glucosides. These phytosterols are commonly derived from the South African star grass, Hypoxis rooperi, or from species of Pinus and Picea. The purported active constituent is termed beta-sitosterol. Additionally, the quantity of beta-sitosterol-beta-D-glucoside is often reported. Although the exact mechanism of action of beta-sitosterols is unknown, it may be related to cholesterol metabolism or anti-inflammatory effects (via interference with prostaglandin metabolism). Compared with placebo, beta-sitosterol improved urinary symptom scores and flow measures (PMID:10368239). A plant food-based diet modifies the serum beta-sitosterol concentration in hyperandrogenic postmenopausal women. This finding indicates that beta-sitosterol can be used as a biomarker of exposure in observational studies or as a compliance indicator in dietary intervention studies of cancer prevention (PMID:14652381). beta-Sitosterol induces apoptosis and activates key caspases in MDA-MB-231 human breast cancer cells (PMID:12579296). Sitosterol is a member of the class of phytosterols that is stigmast-5-ene substituted by a beta-hydroxy group at position 3. It has a role as a sterol methyltransferase inhibitor, an anticholesteremic drug, an antioxidant, a plant metabolite and a mouse metabolite. It is a 3beta-sterol, a stigmastane sterol, a 3beta-hydroxy-Delta(5)-steroid, a C29-steroid and a member of phytosterols. It derives from a hydride of a stigmastane. Active fraction of Solanum trilobatum; reduces side-effects of radiation-induced toxicity. Beta-Sitosterol is a natural product found in Elodea canadensis, Ophiopogon intermedius, and other organisms with data available. beta-Sitosterol is one of several phytosterols (plant sterols) with chemical structures similar to that of cholesterol. Sitosterols are white, waxy powders with a characteristic odor. They are hydrophobic and soluble in alcohols. beta-Sitosterol is found in many foods, some of which are ginseng, globe artichoke, sesbania flower, and common oregano.

It has a role as an EC 5.99.1.3 [DNA topoisomerase (ATP-hydrolysing)] inhibitor, an anti-HIV agent, an antimalarial, an anti-inflammatory agent, an antineoplastic agent and a plant metabolite. It is a pentacyclic triterpenoid and a hydroxy monocarboxylic acid. It derives from a hydride of a lupane. Betulinic Acid has been used in trials studying the treatment of Dysplastic Nevus Syndrome. Betulinic acid is a natural product found in Ficus auriculata, Gladiolus italicus, and other organisms with data available. Betulinic Acid is a pentacyclic lupane-type triterpene derivative of betulin (isolated from the bark of Betula alba, the common white birch) with antiinflammatory, anti-HIV and antineoplastic activities. Betulinic acid induces apoptosis through induction of changes in mitochondrial membrane potential, production of reactive oxygen species, and opening of mitochondrial permeability transition pores, resulting in the release of mitochondrial apogenic factors, activation of caspases, and DNA fragmentation. Although originally thought to exhibit specific cytotoxicity against melanoma cells, this agent has been found to be cytotoxic against non-melanoma tumor cell types including neuroectodermal and brain tumor cells. A lupane-type triterpene derivative of betulin which was originally isolated from BETULA or birch tree. It has anti-inflammatory, anti-HIV and antineoplastic activities. See also: Jujube fruit (part of); Paeonia lactiflora root (part of). Betulinic acid is found in abiyuch. Betulinic acid is a naturally occurring pentacyclic triterpenoid which has anti-retroviral, anti-malarial, and anti-inflammatory properties, as well as a more recently discovered potential as an anticancer agent, by inhibition of topoisomerase. It is found in the bark of several species of plants, principally the white birch (Betula pubescens) from which it gets its name, but also the Ber tree (Ziziphus mauritiana), the tropical carnivorous plants Triphyophyllum peltatum and Ancistrocladus heyneanus, Diospyros leucomelas a member of the persimmon family, Tetracera boiviniana, the jambul (Syzygium formosanum), flowering quince (Chaenomeles sinensis), Rosemary, and Pulsatilla chinensis. Controversial is a role of p53 in betulinic acid-induced apoptosis. Fulda suggested p53-independent mechanism of the apoptosis, basing on fact of no accumulation of wild-type p53 detected upon treatment with the betulinic acid, whereas wild-type p53 protein strongly increased after treatment with doxorubicin. The suggestion is supported by study of Raisova. On the other hand Rieber suggested that betulinic acid exerts its inhibitory effect on human metastatic melanoma partly by increasing p53 A pentacyclic triterpenoid that is lupane having a double bond at position 20(29) as well as 3beta-hydroxy and 28-carboxy substituents.

Oleanolic acid is a pentacyclic triterpene, found in the non-glyceride fraction of olive pomace oil (Olive pomace oil, also known as "orujo" olive oil, is a blend of refined-pomace oil and virgin olive oil, fit for human consumption). Pentacyclic triterpenes are natural compounds which are widely distributed in plants. These natural products have been demonstrated to possess anti-inflammatory properties. Triterpenoids have been reported to possess antioxidant properties, since they prevent lipid peroxidation and suppress superoxide anion generation.
