Isopimaric acid
Isopimaric acid is a diterpenoid, a carbotricyclic compound and a monocarboxylic acid. It is a conjugate acid of an isopimarate. It derives from a hydride of an isopimara-7,15-diene. Isopimaric acid is a natural product found in Pinus brutia var. eldarica, Halocarpus bidwillii, and other organisms with data available. Isopimaric acid is isolated from Pinus palustris (pitch pine).

Isopimaric acid is a potent opener of large conductance calcium activated K+ (BK) channels.
Oryzalexin E
Oryzalexin E is found in rice. Phytoalexin from rice leaves. Phytoalexin from rice leaves. Oryzalexin E is found in rice.
ent-8(14),15-Pimaradiene
ent-8(14),15-Pimaradiene is found in fruits. ent-8(14),15-Pimaradiene is a constituent of Aralia racemosa (American spikenard). Constituent of Aralia racemosa (American spikenard). ent-8(14),15-Pimaradiene is found in fruits.
Oryzalexin A
Oryzalexin a, also known as 3a,7-oxo-ent-sandaracopimaradiene, is a member of the class of compounds known as diterpenoids. Diterpenoids are terpene compounds formed by four isoprene units. Oryzalexin a is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Oryzalexin a can be found in rice, which makes oryzalexin a a potential biomarker for the consumption of this food product.
(ent-7alpha)-7-Hydroxy-8(14),15-pimaradien-19-oic acid
7alpha-7-Hydroxy-8(14),15-isopimaradien-18-oic acid is found in alcoholic beverages. 7alpha-7-Hydroxy-8(14),15-isopimaradien-18-oic acid is a constituent of Juniperus communis (juniper). Constituent of Juniperus communis (juniper). 7alpha-7-Hydroxy-8(14),15-isopimaradien-18-oic acid is found in alcoholic beverages and fruits.
Momilactone B
Momilactone B is found in cereals and cereal products. Momilactone B is a constituent of Oryza sativa (rice) Momilactone B is an allelopathic agent produced from the roots of rice (Oryza sativa L.) (100 mg from 200 kg dry rice husk). It has been shown to be produced in high concentrations by the roots of rice seedlings. The production of momilactone B has also been induced in response to infection by blast fungus (Pyricularia oryzae) or irradiated with UV light. More recently is has been shown to be a potential chemotherapeutic agent against human colon cancer. The second step is the cyclization of syn-CDP to 9 -pimara-7,15-diene. This step is initiated by the elimination of the diphosphate group, a type A cyclization. The genes encoding for the type A cyclase were found by Otomo et al. in 2004. It is suggested that OsKS4, located on chromosome 4 (14.3cM) is one of the genes responsible for phytoalexin biosynthesis. After UV-radiation, OsKS4 mRNA levels rise drastically in response to the attack. Constituent of Oryza sativa (rice)
ent-Sandaracopimaradiene
Ent-sandaracopimaradiene, also known as (-)-8(14),15-isopimaradiene or (-)-isopimara-8(14),15-diene, is a member of the class of compounds known as diterpenoids. Diterpenoids are terpene compounds formed by four isoprene units. Thus, ent-sandaracopimaradiene is considered to be an isoprenoid lipid molecule. Ent-sandaracopimaradiene can be found in rice, which makes ent-sandaracopimaradiene a potential biomarker for the consumption of this food product.
