Kaempferol is a polyphenol antioxidant found in fruits and vegetables, has beneficial effects in reducing the risk of chronic diseases, especially cancer, it may help to promote the development of cancer by augmenting the body's antioxidant defence against free radicals,and inhibit cancer cell growth and angiogenesis and induce cancer cell apoptosis.

Alisol B, a novel inhibitor of the sarcoplasmic/endoplasmic reticulum Ca(2+) ATPase pump, induces autophagy, endoplasmic reticulum stress, and apoptosis.Alisol B may be a potential novel therapeutic molecule for bone disorders through targeting the differentiation of osteoclasts as well as their functions. Alisol B also inhibited RANKL-induced expression of NFATc1 and c-Fos, which are key transcription factors for osteoclastogenesis.

Epimedin A,epimendin B, epimendin C, icariin and baohuoside are flavonoids, main active ingredient in Epimedium, have clear anti-osteoporosis effect, the accumulation of epimedins A, B, C, and icariin in a traditional medicinal plant could be suppressed by light stress.

Seneciphylline, one of the hepatotoxic pyrolizidine alkaloids, has mutagenic activity in Drosophila and their transfer into rat milk.Seneciphylline can significantly increased the activities of epoxide hydrase and glutathione-S-transferase but cause reduction of cytochrome P-450 and related monooxygenase activities.

Kaempferol 3-O-gentiobioside (K3G), isolated from C. alata as an abundant flavonoid glycoside, K3G has antiinflammatory activity, shows weak inhibitory effects on Concanavalin A-induced histamine release, 5-lipoxygenase, and COX-1.

Polygalic acid, a triterpenoid saponin, shows expectorant, emetic and stimulant effects.

Tubuloside A has anti-inflammatory, antioxidative and hepatoprotective activities. Tubuloside A shows stronger free radical scavenging activities than alpha-tocopherol on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and xanthine/xanthine oxidase (XOD) generated superoxide anion radical (O2-.).

Dehydrocorydalin has anti-inflammatory,antinociceptive,antiplatelet,and anti-tumor effects and can protect the cardiovascular system. Dehydrocorydaline stimulates p38 MAPK activation, which can enhance heterodimerization of MyoD and E proteins, thus resulting in MyoD activation and myoblast differentiation. Dehydrocorydaline inhibits MCF-7 cell proliferation by inducing apoptosis mediated by regulating Bax/Bcl-2, activating caspases as well as cleaving PARP.

10-Deacetyltaxol and cephalomannine have cytotoxicity in human glial and neuroblastoma cell-lines, the tumors of the central and peripheral nervous system are sensitive to 10-deacetyltaxol and cephalomannine and these drugs are less toxic than taxol but remain within a therapeutic range.

Plantamajoside has antibacterial activity, and has inhibition activity against cAMP phosphodiesterase and 5-lipoxygenase and antioxidant activity.

10-Deacetyl-7-xylosyl paclitaxel has long been used in Chinese clinics to treat cancer, it may target mitochondrial permeability transition pore (mPTP).

Baicalin methyl ester shows inhibitory effects on the Avian Myeloblastosis Virus reverse transcriptase (AMV-RT).

Liensinine is a human ether-a-go-go-related gene (hERG) inhibitor and a novel autophagy/mitophagy inhibitor, which can antagonize the ventricular arrhythmias. It exerts remarkable effect against thrombosis and possesses strong effect against platelet aggregation and coagulation.

Oroxin B can selectively induce tumor-suppressive ER stress and concurrently inhibit tumor-adaptive ER stress in B-lymphoma cells for effective anti-lymphoma therapy.

Kirenol possesses anti-bacteria, immunosuppression, anti-obesity, anti-oxidant, anti-inflammatory, anti-allergic, and anti-arthritic activities. Kirenol has significant potential for its discovery as a new lead compound for management of topical pain and inflammation; it can upregulate nuclear Annexin-1 which interacts with NF-κB to attenuate synovial inflammation of collagen-induced arthritis in rats. Kirenol can attenuate experimental autoimmune encephalomyelitis by inhibiting differentiation of Th1 and th17 cells and inducing apoptosis of effector T cells. Kirenol activates the BMP and Wnt/β-catenin signaling pathways.

Ruscogenin exerts significant anti-inflammatory and anti-thrombotic activities.Ruscogenin significantly attenuates LPS-induced acute lung injury (ALI )via inhibiting expressions of TF and iNOS and NF-κB p65 activation, it inhibits activation of neutrophil through cPLA 2 , PAK, Akt, MAPKs, cAMP, and PKA signaling pathways.

Dehydrocostus lactone(DCL) is exuded from sunflower roots and low DCL concentrations stimulate germination of the root parasite Orobanche cumana.
