“…[14] In addition to this, 'decanal' and 'myrcene' rich oils have also been identified from China. [17] Further, the leaf essential oil of H. cordata from Vietnam was rich in myrcene, 2-undecanone, and (Z)-b-ocimene. [18] However, in South Korea myrcene, cis-ocimene and decanal were the dominant constituents of leaf and aerial-stem oils, while the underground-stem oil was enriched prominently with monoterpenes (myrcene, cis-ocimene, camphene, sabinene, b-pinene, limonene, and terpinolene).…”

Fish-mint (Houttuynia cordataThunb.), belonging to family Saururaceae, has long been used as food and traditional herbal medicine. The present study was framed to assess the changes occurring in the essential-oil composition of H. cordata during annual growth and to evaluate allelopathic, antibacterial, antifungal, and antiacetylcholinesterase activities. The essential-oil content ranged from 0.06 - 0.14% and 0.08 - 0.16% in aerial parts and underground stem, respectively. The essential oils were analysed by GC-FID, GC/MS, and NMR ( H and C). Major constituents of aerial-parts oil was 2-undecanone (19.4 - 56.3%), myrcene (2.6 - 44.3%), ethyl decanoate (0.0 - 10.6%), ethyl dodecanoate (1.1 - 8.6%), 2-tridecanone (0.5 - 8.3%), and decanal (1.1 - 6.9%). However, major constituents of underground-stem oil were 2-undecanone (29.5 - 42.3%), myrcene (14.4 - 20.8%), sabinene (6.0 - 11.1%), 2-tridecanone (1.8 - 10.5%), β-pinene (5.3 - 10.0%), and ethyl dodecanoate (0.8 - 7.3%). Cluster analysis revealed that essential-oil composition varied substantially due to the plant parts and season of collection. The oils exhibited significant allelopathic (inhibition: 77.8 - 88.8%; LD : 2.45 - 3.05 μl/plate), antibacterial (MIC: 0.52 - 2.08 μl/ml; MBC: bacteriostatic) and antifungal (MIC: 2.08 - 33.33 μl/ml; MFC: 4.16 - 33.33 μl/ml) activities. The results indicate that the essential oil from H. cordata has a significant potential to allow future exploration and exploitation as a natural antimicrobial and allelopathic agent.

“…cordata new line w01-100 with desirable traits like disease resistance, high-quality and yield, was selected out from a collection of more than one hundred H. cordata accessions present in China. The line belongs to chemotype myrcene (Chen et al, 2008) and has chromosome number 90 (Wu et al, 2003). It has been planted for commercial purposes for years in Good Agricultural Practices (GAP) base of 999 Pharmaceutical Group (China).…”

a b s t r a c tHouttuynia cordata Thunb. is an edible herb with a variety of pharmacological activities, but only limited information is available about its response towards potassium supplementation. Sterile plantlets were cultured in media with different potassium levels, and parameters related to growth, foliar potassium, water and chlorophyll contents, photosynthesis, transpiration, H 2 O 2 contents and antioxidative enzyme activities were determined after a month. Results showed that 1.28 mM potassium was the optimum for H. cordata as highest values of dry weight, shoot height, root length and number were obtained at this concentration. The optimum potassium concentration resulted in the maximum net photosynthetic rate which could be associated with the highest chlorophyll content rather than limited stomatal conductance. The supply of surplus potassium resulted in higher content of foliar potassium, but negatively correlated with the biomass. Both potassium starvation (0 mM) and high potassium (>1.28 mM) could lead to water loss through high transpiration rate and low water absorption, respectively, and resulted in H 2 O 2 accumulation and increased activities of catalase and peroxidase, which suggested induction of oxidative stress. Moreover, H. cordata showed the minimum of H 2 O 2 content and the maximum of superoxide dismutase activity on 1.28 mM potassium, implying its role in inducing tolerance against oxidative stress.

“…H. cordata populations exhibit high variations in chromosome number and at the nuclear genome level (Wu et al, 2003(Wu et al, , 2005a. Therefore, the composition of the essential oil shows variations among H. cordata accessions (Chen et al, 2008).…”

Houttuynia cordata Thunb. is a medicinal herb under the family Saururaceae, distributed in South-East Asia, mainly in China, Japan, Thailand and North-East India. In the present study, percentage of total chlorophyll, carotene and extractable essential oil were estimated in active growing season (April to July in 2008) in five different populations i.e. Nalbari (NL), Guwahati (GH), Nagaon (NG), Jorhat (JR) and Dhemaji (DH) in the Brahmaputra valley of Assam. Average percentage of total chlorophyll, carotene and extractable essential oil were found to be 1.77%, 3.0% and 0.065% respectively. The simple linear curve fit of EO (%) with chlorophyll (%) and carotene (%) had shown that the EO (%) could be significantly related to the lowest chlorophyll (%) and the highest carotenoid (%) in the samples. A total of 28 components were identified by GC-MS analysis and the percentage of methyl nonyl ketone was the highest in all the five populations (33.722±1.261). Isoenzymes of enzyme peroxidase, present in H. cordata were studied to know the molecular identity of the herb in the valley. The total numbers of isoenzymes were found to be six, which was comparable with that of Sichuan, China. There is no geographical variance, at least regarding the number of peroxidase isozymes present, in the H. cordata plants collected from Jorhat district of Assam, North East India and that of Sichuan, China.
