Millettia pinnata L. is a leguminous tree with great potential in biodiesel applications and also a typical semi-mangrove. In this review, we presented several aspects about the recent research progress in molecular biology of M. pinnata. We descrived several types of molecular markers used to assess the genetic diversity and phylogeny of this species, genome and transcriptome analyses based on high-throughput sequencing platform accomplished for this species, and several gene and genomic sequences of this species isolated for further research. Finally, based on the current research progress, we proposed some orientations for future molecular biology research on M. pinnata.

To use the single-pass intestine perfusion (SPIP) model and HPLC to determine the concentration of formononetin, the effect of quality concentrations of formononetin, different intestinal segments and P-glycoprotein inhibitor on intestinal absorption of formononetin, in order to observe the intestinal absorption mechanism of formononetin from Millettia nitita var. hirsutissima in rats. The experimental results showed that the qulaity concentration of formononetin in the perfusate had no significant effect on the absorption rate constant (K(a)) and the apparent absorption coefficient (P(app)); K(a) and P(app) of formononetin in duodenum, jejunum and ileum showed no significant difference. However, K(a) was significantly higher than that in colon (P < 0.05), with significant difference between that in intestinum tenue and colon. P-glycoprotein inhibitor verapamil showed significant difference in K(a) and P(app) in intestinal segments (P < 0.05). This indicated that the absorption mechanism of formononein in rat intestinal tracts passive diffusion, without any saturated absorption. Formononein is absorbed well in all intestines. Their absorption windows were mainly concentrated in the intestinum tenue, without specific absorption sites. Formononein may be the substrate of P-glycoprotein.

The current study to separate and identify constituents from Millettia nitida var. hirsutissima. The compounds from Millettia nitida var. hirsutissima were isolated by means of various chromatographic techniques such as column chromatography over ODS and Sephadex LH-20, preparative HPLC, and the structures of these isolated compounds were identified through spectroscopic analyses. Nine isoflavonoids and two flavans were isolated and identified as 5-O-methy genistein (1), 7-hydroxy-3',4'-dimethoxyisoflavone (2), ononin (3), catechin (4), formononetin (5), genistein (6), calycosin (7), (-)-gallocatechin (8), sissotrin (9), wistin (10), daidzin (11). Compounds 1, 2, 9 are obtained from the genus Millettia for the first time,and compounds 4, 8 are isolated from this plant for the first time.

Growing patterns of pediculocidal drug resistance towards head louse laid the foundation for research in exploring novel anti-lice agents from medicinal plants. In the present study, various extracts of Pongamia pinnata leaves were tested against the head louse Pediculus humanus capitis. A filter paper diffusion method was conducted for determining the potential pediculocidal and ovicidal activity of chloroform, petroleum ether, methanol, and water extracts of P. pinnata leaves. The findings revealed that petroleum ether extracts possess excellent anti-lice activity with values ranging between 50.3% and 100% where as chloroform and methanol extracts showed moderate pediculocidal effects. The chloroform and methanol extracts were also successful in inhibiting nymph emergence and the petroleum ether extract was the most effective with a complete inhibition of emergence. Water extract was devoid of both pediculocidal and ovicidal activities. All the results were well comparable with benzoyl benzoate (25% w/v). These results showed the prospect of using P. pinnata leave extracts against P. humanus capitis in difficult situations of emergence of resistance to synthetic anti-lice agents.

The Korean traditional medicinal (KTM) herbs such as Angelicae gigantis, Rehmannia glutinosa, Paeoniae lactiflora, Cnidii officinale, Salviae miltiorrhizae, and Millettia reticulata, and prescribed formula Samultang, and Bohyultang improve the function of the hematopoietic system and nourishing the body to promote health. However, there are limited scientific background on the mode of action of these medicine. To understand the diverse actions following traditional medicine stimulation, we determined the production of hematopoietic cytokine, thrombopoietin, stem cell factor, and interleukin-3 (IL-3) in KlM treated bone marrow cells. When bone marrow cells were treated with KTM, the expression of hematopoietic cytokine were increased in RT-PCR and ELISA analysis. Furthermore, when the bone marrow cells were separated into adherent celis and suspension cells and were treated with KTM, we found the increase of TPO gene expressions in suspension cells. Meanwhile, other hematopoietic cytokine gene expression in bone marrow cells was higher as whole than when adherent cells and suspension cells was separated. Therefore, we could know the interaction of two cells that increases the cytokine expression. These results suggest that KTM has hematopoietic effects through increasing the production of cytokine.

Ultra-fast performance liquid chromatography-mass spectrometry( UFLC-MS/MS) was used to study the anti-inflammatory active ingredient of Millettia pachyloba,6-methoxy-8,8-dimethyl-3-( 2,4,5-trimethoxyphenyl)-4 H,8 H-pyrano[2,3-f]chromen-4-one( HN-1),in liver microsomes of rats,mice,rhesus monkeys,Beagle dogs and humans metabolic stability,and compare the metabolic differences between different species. The metabolic phenotype in human liver microsomes was determined by chemical inhibitor method. Using UPLC-Q-TOF-MS/MS detection method,the in vitro metabolites of various liver microsomes were preliminarily inferred by comparing the samples incubated for 0 min and 60 min in vitro. The metabolites of HN-1 in SD rats were presumed by comparing feces,urine,plasma blanks and samples after administration. The results showed that the metabolism of HN-1 in various liver microsomes was stable,and the metabolic properties of dog and human liver microsomes were the closest. It is mainly catabolized by CYP1 A1,CYP2 D6 and CYP3 A4 isoenzymes in human liver microsomes. The metabolites of HN-1 in vitro and in vivo,including 3 in vitro metabolites and5 in vivo metabolites,were preliminarily estimated. The results laid the foundation for further pharmacological studies of HN-1.
