Rhodamine B is an organic chloride salt having N-[9-(2-carboxyphenyl)-6-(diethylamino)-3H-xanthen-3-ylidene]-N-ethylethanaminium as the counterion. An amphoteric dye commonly used as a fluorochrome. It has a role as a fluorescent probe, a fluorochrome and a histological dye. It is an organic chloride salt and a xanthene dye. It contains a rhodamine B(1+). Rhodamine B is used as a tracer dye in water to determine the rate and direction of flow and transport. It is a staining fluorescent dye used in fluorescence microscopy, flow cytometry, fluorescence correlation spectroscopy and ELISA in biotechnology fields.

Betulinic acid methyl ester showed antiplasmodial activity against chloroquine-resistant Plasmodium falciparum parasites in vitro.It also inhibited B16 2F2 cell proliferation by induction of apoptosis.

Nortrachelogenin is a novel agent for prostate cancer therapy with ability to inhibit Akt membrane localization and activity as well as the activation of growth factor receptors, thereby efficiently synergizing with tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), exposure.Nortrachelogenin has anti-inflammatory properties,it shows moderate inhibiting activities on NF- κB signaling pathway induced by TNF-α , with the IC50 value of 49.4 uM. Nortrachelogenin also shows anti-plasmodium activity of 14.50 dg/ml. (+ )-Nortrachelogenin shows effects on the central nervous system producing depression in rabbits, it is moderately active against HIV-1 in vitro. (-)-Nortrachelogenin exerts its antibacterial effect by disorganizing and perturbing the cytoplasmic membrane, it also can induce membrane disruption and caspase-dependent apoptosis.

Hederagenin shows anti-cancer,anti-inflammatory, antidepressant-like ,anticomplementary, and antimutagenic effects, it can evoke hemolysis on the erythrocytes, and has cytotoxic on various tumor cell lines, P-388, L-1210, U-937, HL-60, SNU-5 and HepG2. Hederagenin can inhibit LPS-stimulated expression of iNOS, COX-2, and NF-κB, regulate monoamine neurotransmitters and 5-HTT mRNA expression. Hederagenin is a sapogenin that is olean-12-en-28-oic acid substituted by hydroxy groups at positions 3 and 23 (the 3beta stereoisomer). It has a role as a plant metabolite. It is a pentacyclic triterpenoid, a sapogenin and a dihydroxy monocarboxylic acid. It is functionally related to an oleanolic acid. It is a conjugate acid of a hederagenin(1-). It derives from a hydride of an oleanane.
